Étude des facteurs influençant la susceptibilité à l'infection au VIH chez des femmes africaines

Chez la femme, la majorité des cas d’infection au VIH sont acquis lors de relations hétérosexuelles. Cependant, très peu d’informations sont disponibles concernant l’immunité locale naturelle du tractus génital féminin, les facteurs influençant la susceptibilité à l’infection au VIH dans ce compartiment, ainsi que la réponse immunitaire de la muqueuse enclenchée après l’infection. Le but de notre projet est donc d’étudier certains facteurs pouvant être impliqués dans la susceptibilité à l’infection au VIH, afin de mieux comprendre l’immunité du tractus génital féminin. Nous avons, dans un premier temps, analysé le rôle du polymorphisme des gènes HLA-G et HLA-E sur la susceptibilité au VIH dans une population de femmes zimbabwéennes. La présence de l’allèle HLA-G*0105N, en combinaison avec le génotype HLA-EG/HLA-EG, était associée avec une diminution du risque d’infection. Puis, dans une étude cas-contrôle de travailleuses du sexe (TS) du Bénin, nous avons mesuré l’expression de HLA-G soluble au niveau du plasma. Nous avons observé une différence significative dans l’expression de HLA-G soluble, celle-ci étant plus faible dans le groupe des TS VIH positives comparé aux groupes de TS VIH négatives et de femmes VIH négatives de la population générale. Nous avons aussi analysé l’expression de cytokines et chimiokines dans le sérum et le tractus génital des participantes de l’étude du Bénin. Nous avons constaté que chez les TS VIH positives il y avait une expression plus élevée des chimiokines MPC-3, IP-10 et MIG dans le tractus génital et le sérum comparativement aux deux autres groupes. Les patrons d’expression des cytokines variaient selon les compartiments : le niveau de TNF-α et IFN-γ était plus élevé dans le tractus génital des TS VIH positives, alors que le niveau d’IL-2, d’IL-10 et de TNF-α était plus faible dans le sang des TS VIH positives, comparativement aux deux autres groupes. Ainsi, au niveau du tractus génital des femmes VIH positives, il semble y avoir une activation chronique du système immunitaire dans le but de favoriser la dissémination/perpétuation du virus. Les patrons d’expression différents entre le milieu systémique et génital nous montrent que l’immunité présente dans un compartiment n’est pas nécessairement le reflet de l’autre. Nous avons aussi observé une augmentation significative des niveaux d’IL-4, de MIP-1α, de MIP-1β et de MCP-1 dans le sérum des TS VIH négatives. Ces personnes, hautement exposées mais non infectées, semblent démontrer une plus grande capacité à enclencher une réponse immunitaire précoce pour empêcher la dissémination du virus. Notre étude a donc permis d’acquérir de nouvelles connaissances sur l’immunité du tractus génital féminin en relation avec l’infection au VIH.

Rôle de protéines épididymaires humaines et murines dans les fonctions spermatiques

L’infertilité affecte jusqu’à 15-20% des couples en âge de se reproduire. C’est pourquoi, mieux comprendre les mécanismes à la base de la fécondation est essentiel pour l’identification de nouvelles causes d’infertilité et l’optimisation des techniques de reproduction assistée. La capacitation est une étape de la maturation des spermatozoïdes qui se déroule dans le tractus génital femelle. Elle est requise pour la fécondation d’un ovocyte. Notre laboratoire a démontré que des protéines du plasma séminal bovin, appelées protéines Binder of SPerm (BSP), se lient aux phospholipides portant des groupements choline à la surface de la membrane des spermatozoïdes lors de l’éjaculation et promeuvent la capacitation. Ces protéines exprimées par les vésicules séminales sont ubiquitaires chez les mammifères et ont été étudiées chez plusieurs espèces dont l’étalon, le porc, le bouc et le bélier. Récemment, l’expression de gènes homologues aux BSP a été découverte dans les épididymes d’humains (BSPH1) et de souris (Bsph1 et Bsph2). Notre hypothèse est que les BSP chez ces deux espèces sont ajoutées aux spermatozoïdes lors de la maturation épididymaire et ont des rôles dans les fonctions spermatiques, similaires à ceux des protéines BSP bovines. Les protéines BSP humaines et murines représentent une faible fraction des protéines totales du plasma séminal. Pour cette raison, afin d’étudier leurs caractéristiques biochimiques et fonctionnelles, des protéines recombinantes ont été produites. Les protéines recombinantes ont été exprimées dans des cellules Escherichia coli origami B(DE3)pLysS en utilisant un vecteur d’expression pET32a. Suivant la lyse cellulaire, les protéines ont été dénaturées avec de l’urée et purifiées par chromatographie d’affinité sur ions métalliques immobilisés. Une fois liées à la colonne, les protéines ont été repliées à l’aide d’un gradient d’urée décroissant avant d’être éluées. Cette méthode a mené à la production de trois protéines recombinantes (rec-BSPH1 humaine, rec-BSPH1 murine et rec-BSPH2 murine) pures et fonctionnelles. Des expériences de chromatographie d’affinité et de co-sédimentation nous ont permis de démontrer que les trois protéines peuvent se lier à des ligands connus des protéines BSP comme la gélatine et l’héparine en plus de pouvoir se lier aux spermatozoïdes. Nos études ont également révélées que les deux protéines rec-BSPH1 peuvent se lier aux liposomes de phosphatidylcholine (PC) et sont capable de promouvoir la capacitation des spermatozoïdes. À l’opposé, rec-BSPH2 ne peut ni se lier aux liposomes de PC, ni stimuler la capacitation. Finalement, les protéines recombinantes n’ont aucun effet sur la réaction acrosomique ou sur la motilité des spermatozoïdes. Chez les bovins, les protéines BSP induisent la capacitation grâce des interactions avec les lipoprotéines de haute densité (HDL) et les glycosaminoglycanes. Puisque le HDL est également un joueur important de la capacitation chez la souris, le rôle de la protéine native BSPH1 murine au niveau de la capacitation induite par le HDL a été étudié. Les résultats obtenus suggèrent que, in vivo, la protéine BSPH1 de souris serait impliquée dans la capacitation via une interaction directe avec le HDL. Comme les protéines BSPH1 humaines et murines sont orthologues, ces résultats pourraient aussi s’appliquer à la fertilité humaine. Les résultats présentés dans cette thèse pourraient mener à une meilleure compréhension de la fertilité masculine et aider à améliorer les techniques de reproduction assistée. Ils pourraient également mener au développement de nouveaux tests diagnostiques ou de contraceptifs masculins.

Étude de l’immunité mucosale génitale chez des femmes béninoises hautement exposées au VIH-1 séronégatives (HESN) et séropositives.

Introduction : Aujourd’hui, 35,3 millions de personnes vivent avec le virus de l’immunodéficience humaine (VIH)-1 dans le monde ; l’Afrique subsaharienne concentre 70% des nouvelles infections et les femmes en représentent plus de la moitié. Le mode de transmission du VIH le plus répandu est par voie mucosale génitale suite à des relations sexuelles. Le tractus génital féminin (TGF) possède un milieu immunitaire complexe qui doit contrer l’invasion par des pathogènes tout en maintenant la tolérance/contrôle de la flore normale vaginale étant sous la pression de procréation sous influence des hormones sexuelles. De plus, les mécanismes favorisant ou prévenant l’infection du TGF par le VIH ne sont pas précisément identifiés. Hypothèse : Le contexte inflammatoire mucosal génital et la résultante de dialogues intercellulaires tel qu’entre les cellules épithéliales génitales (CEG) et les cellules dendritiques myéloïdes (mDC), qui sont des premières à rencontrer le virus aux portes d’entrée mucosales, modulent l’activité des lymphocytes qui est déterminante dans le type de réponse immunitaire élaborée par l’hôte. Méthodologie : Des spécimens provenant d’une cohorte de travailleuses du sexe (TS) recrutées à Cotonou au Bénin en Afrique subsaharienne ont été analysés. Nous avons caractérisé le milieu mucosal génital féminin hautement exposé au VIH de TS séronégatives (highly exposed seronegative; HESN) en comparaison avec celui de TS séropositives. Brièvement, les liquides cervicaux-vaginaux ont été déterminés par des techniques de multiplexes/Luminex ou par ELISA et le milieu cellulaire a été décrit suite à des analyses de cytométrie en flux (phénotypage et tri cellulaire). Résultats : Nous avons observé la présence augmentée d’un facteur soluble antiviral, immunomodulateur et antiprolifératif sécrété dans le TGF des TS HESN qui est l’interféron (IFN)-α. La présence augmentée de cette cytokine suggère l’existence possible de connexions intercellulaires clés qui pourraient mener à une régulation homéostatique du compartiment immunitaire génital permettant de contrôler l’infection par le VIH-1. En étudiant l’expression de molécules impliquées dans les voies de signalisation associées à la production d’IFN-α dans les CEG et les cellules myéloïdes du TGF, nous avons pu mettre en évidence l’existence d’un microenvironnement présentant un profil «tolérogénique/régulateur» dans le TGF des TS HESN. Conclusion : Nos observations nous ont permis d’élucider certaines hypothèses sur un potentiel mécanisme d’immunité naturelle protecteur chez les TS HESN. De plus, nous sommes des premiers à décrire une population myéloïde présentant des caractéristiques de DC «tolérogéniques» de par leur expression d’interleukine (IL)-10, de human leukocyte antigen (HLA)-G et de immunoglobulin-like transcript (ILT)-4 dans le TGF de TS HESN. Cette étude aura des implications majeures dans le développement de stratégies d’interventions préventives afin de moduler des conditions inflammatoires préexistantes ainsi établissant une défense mucosale rapide et durable contre le VIH-1.

Are primary and secondary provoked vestibulodynia two different entities? A comparison of pain, psychosocial and sexual characteristics.

Introduction Provoked vestibulodynia (PVD) is suspected to be the most frequent cause of vulvodynia in premenopausal women. Based on the onset of PVD relative to the start of sexual experience, PVD can be divided into primary (PVD1) and secondary PVD (PVD2). Studies comparing these PVD subgroups are inconclusive as to whether differences exist in sexual and psychosocial functioning. Aim The aim of this study was to compare the pain, sexual and psychosocial functioning of a large clinical and community-based sample of premenopausal women with PVD1 and PVD2. Methods A total of 269 women (n = 94 PVD1; n = 175 PVD2) completed measures on sociodemographics, pain, sexual, and psychosocial functioning. Main Outcome Measures Dependent variables were the 0–10 pain numerical rating scale, McGill–Melzack Pain Questionnaire, Female Sexual Function Index, Global Measure of Sexual Satisfaction, Beck Depression Inventory-II, Painful Intercourse Self-Efficacy Scale, Pain Catastrophizing Scale, State-Trait Anxiety Inventory Trait Subscale, Ambivalence over Emotional Expression Questionnaire, Hurlbert Index of Sexual Assertiveness, Experiences in Close Relationships Scale—Revised, and Dyadic Adjustment Scale-Revised. Results At first sexual relationship, women with PVD2 were significantly younger than women with PVD1 (P < 0.01). The average relationship duration was significantly longer in women with PVD2 compared with women with PVD1 (P < 0.01). Although women with PVD1 described a significantly longer duration of pain compared with women with PVD2 (P < 0.01), no significant subtype differences were found in pain intensity during intercourse. When controlling for the sociodemographics mentioned earlier, no significant differences were found in sexual, psychological, and relational functioning between the PVD subgroups. Nevertheless, on average, both groups were in the clinical range of sexual dysfunction and reported impaired psychological functioning. Conclusions The findings show that there are no significant differences in the sexual and psychosocial profiles of women with PVD1 and PVD2. Results suggest that similar psychosocial and sex therapy interventions should be offered to both subgroups of PVD.

To say or not to say : dyadic ambivalence over emotional expression and its associations with pain, sexuality, and distress in couples coping with provoked vestibulodynia.

Introduction Provoked vestibulodynia (PVD) is a highly prevalent and taxing female genital pain condition. Despite the intimate nature of this pain and the fact that affective factors such as anxiety have been shown to modulate its manifestations, no study has yet explored the emotional regulation of couples in which the woman suffers from PVD. Aim Ambivalence over emotional expression (AEE) is an emotional regulation variable that quantifies the extent to which a person is comfortable with the way she or he expresses emotions. We examined whether the dyadic AEE of couples in which the woman suffers from PVD was differentially associated with women's pain and couples' psychological, sexual, and relational functioning. Methods Couples (N = 254), in which the woman suffered from PVD, completed the AEE questionnaire. A couple typology of dyadic AEE was created. Main Outcome Measures Dependent measures for both members of the couple were the global measure of sexual satisfaction scale, the Beck depression inventory II, and the revised dyadic adjustment scale. The female sexual function index and the sexual history form were used to assess the sexual function of women and men, respectively. Women also completed the pain rating index of the McGill pain questionnaire. Results Couples, in which both partners were considered low on AEE, had the highest scores on sexual satisfaction (P = 0.02) and function (P < 0.01), the lowest depression scores (P < 0.01), and the best dyadic adjustment (P = 0.02). No difference in pain intensity was found between couples. Conclusions Findings suggest that, for couples in which the woman suffers from PVD, an emotional regulation that is low in ambivalence in both partners is associated with better psychological, sexual, and relational outcomes. Results indicate that emotional regulation may be important to consider in the assessment and treatment of couples coping with PVD.

Women with provoked vestibulodynia experience clinically significant reductions in pain regardless of treatment : results from a 2-year follow up study.

Introduction Provoked vestibulodynia (PVD) is a prevalent genital pain syndrome that has been assumed to be chronic, with little spontaneous remission. Despite this assumption, there is a dearth of empirical evidence regarding the progression of PVD in a natural setting. Although many treatments are available, there is no single treatment that has demonstrated efficacy above others. Aims The aims of this secondary analysis of a prospective study were to (i) assess changes over a 2-year period in pain, depressive symptoms, and sexual outcomes in women with PVD; and (ii) examine changes based on treatment(s) type. Methods Participants completed questionnaire packages at Time 1 and a follow-up package 2 years later. Main Outcome Measures Visual analog scale of genital pain, Global Measure of Sexual Satisfaction, Female Sexual Function Index, Beck Depression Inventory, Dyadic Adjustment Scale, and sexual intercourse attempts over the past month. Results Two hundred thirty-nine women with PVD completed both time one and two questionnaires. For the sample as a whole, there was significant improvement over 2 years on pain ratings, sexual satisfaction, sexual function, and depressive symptoms. The most commonly received treatments were physical therapy, sex/psychotherapy, and medical treatment, although 41.0% did not undergo any treatment. Women receiving no treatment also improved significantly on pain ratings. No single treatment type predicted better outcome for any variable except depressive symptoms, in which women who underwent surgery were more likely to improve. Discussion These results suggest that PVD may significantly reduce in severity over time. Participants demonstrated clinically significant pain improvement, even when they did not receive treatment. Furthermore, the only single treatment type predicting better outcomes was surgery, and only for depressive symptoms, accounting for only 2.3% of the variance. These data do not demonstrate the superiority of any one treatment and underscore the need to have control groups in PVD treatment trials, otherwise improvements may simply be the result of natural progression.

Untersuchungen zur Eliminierung und Resorption von Zink aus Säugerspermatozoen während der Nebenhodenpassage

Während der Spermatogenese wird das Element Zink an die Sulfhydrylreste der Cysteine in den Mantelfaserproteinen der Spermienflagellen gebunden. So kann in den noch unreifen Mantelfasern die ungerichtete Ausbildung von Disulfidbrücken verhindert werden. Im Zuge der Spermatozoenreifung während der Nebenhodenpassage wird dieses Zink androgenabhängig zu einem hohen Prozentsatz wieder eliminiert. Die nun gerichtete Ausbildung von Disulfidbrücken ermöglicht die Versteifung der Mantelfasern. Diese Rigidität stellt die Voraussetzung zur progressiven Motilität dar, ohne die eine Fertilisierung der Eizelle im weiblichen Genitaltrakt nicht möglich ist. Da eine negative Korrelation zwischen dem Zinkgehalt von Flagellen und ihrer Motilität besteht (Henkel et al., 1999), hat die Zinkeliminierung während der Nebenhodenpassage eine entscheidende Bedeutung in der Entwicklung der Spermatozoen. Die vorliegende Arbeit untersucht die Mechanismen der epididymalen Zinkeliminierung sowie die an diesem Prozess beteiligten Komponenten und den Verbleib des eliminierten Zinks am System des Bullen, der Ratte und des Menschen. Mittels proteinchemischer Verfahren kann im bovinen System ein zinkbindendes 60 kDa-Protein als Albumin identifiziert werden. Ein 80 kDa-Protein mit zinkbindenden Eigenschaften bleibt unidentifiziert. Die Zinkbindungskapazität der fraktionierten Proteine ist dabei im Caput epididymidis am stärksten ausgeprägt. Atomabsorptionsspektralphotometrische Untersuchungen zeigen die höchsten flagellären Zinkwerte in den Spermien des Rete testis und eine Abnahme des Zinkgehalts zwischen Nebenhodenkopf und -körper. Durch Autometallographie kann eine epitheliale Zinkresorption im Nebenhodenschwanz nachgewiesen werden. Dort erfolgt auch die basale Anreicherung des Zinks. Am Zinkstoffwechsel scheint auch der Macrophage Migration Inhibitory Factor (MIF) beteiligt zu sein. Dieser ist ein Zytokin mit Oxidoreduktasecharakter und kommt unter anderem im Nebenhodenepithel sowie in den Vesikeln des Nebenhoden-Fluids der Ratte vor. MIF zeigt in den hier durchgeführten Untersuchungen sowohl in systemhomologer, als auch in rekombinanter Form in vitro eine Zink-eliminierende Wirkung auf Rattenspermatozoen des Caputs und der Cauda epididymidis und hat somit möglicherweise Einfluss auf den Reifungsprozess der Spermien im Nebenhoden.

Supervivencia cáncer específica posterior a nefrectomía radical frente a nefrectomía parcial en carcinoma renal t2: revisión sistemática

Introducción: El tratamiento estándar para los tumores renales localizados es la nefrectomía radical, sin embargo debido a la variación el tamaño del tumor renal en el momento del diagnóstico, se ha reemplazado en algunos casos por la nefrectomía parcial. Objetivo: Este estudio busca comparar el resultado oncológico de la nefrectomía parcial en términos de supervivencia cáncer específica, respecto a la nefrectomía radical, en pacientes mayores de 50 años con carcinoma renal estadio II (T2N0M0) Métodos: Se realizó una revisión sistemática de la literatura, con inclusión de estudios de casos y controles, cohortes y experimentos clínicos aleatorizados incluidos en las bases de datos de MEDLINE , EMBASE y CENTRAL Resultados: La búsqueda inicial emitió un total de 101 resultados, 11 artículos fueron preseleccionados y sólo un artículo cumplió con los criterios de selección; éste se clasificó como nivel de evidencia II. Conclusión: No fue posible concluir su equivalencia oncológica de la nefrectomía radical con la nefrectomía parcial, dado que no hay diseños de estudios que permitan llegar a esta conclusión.

El desempeño de Unamsil en el programa DDR durante el proceso de paz en Sierra Leona. Estudio de caso: los niños soldados. 1998-2005

El interés de este Estudio de Caso es investigar la manera en que la Misión de Paz de la ONU en Sierra Leona (UNAMSIL) redireccionó el programa Desarme, Desmovilización y Reintegración (DDR) hacia los niños soldados durante el post-conflicto en el país. Se analiza cómo a través de la coordinación de diferentes Agencias y Organizaciones Internacionales con UNAMSIL, el Gobierno y la Sociedad Civil hace posible que se refuerce el rol de los Interim Care Centers (ICCs) en donde se enfrentaron las necesidades esenciales de los menores excombatientes para lograr un mejor proceso de su desmovilización y reintegración. Se explica de igual forma, las diferentes herramientas que sirven para llevar a cabo la resolución del conflicto y la reconstrucción de la paz, enfocándose en el peacekeeping, peacemaking y peacebuilding, como mecanismos que ayudaron a crear un espacio seguro para los niños exsoldados. Por último, se exponen los alcances y límites de los ICCs con respecto a la reintegración de los menores excombatientes

Carga viral de seis tipos de Virus del Papiloma Humano de alto riesgo y su asociacion con lesiones cervicales

Introducción: La infección por un tipo de Virus del Papiloma Humano de alto riesgo (VPH-AR), es el factor principal en el desarrollo de Cáncer de Cérvix (CC). La carga viral puede modular esta asociación, por lo que resulta importante su cuantificación y el establecimiento de su relación con lesiones precursoras de CC. Metodología: 60 mujeres con lesiones escamosas intraepiteliales (LEI) y 120 mujeres sin LEI, confirmadas por colposcopia, fueron incluidas en el estudio. Se determinó la carga viral de 6 tipos de VPH-AR, mediante PCR en tiempo real. Se estimaron OR crudos y ajustados para evaluar la asociación entre la carga viral de cada tipo y las lesiones cervicales. Resultados: 93.22% de mujeres con LEI y 91.23% de mujeres negativas, fueron positivas para al menos un tipo de VPH. VPH-18 y VPH-16 fueron los tipos más prevalentes, junto con VPH-31 en mujeres sin LEI. No se encontraron diferencias estadísticamente significativas de las cargas virales entre éstos dos grupos, aunque se observó un mayor carga viral en lesiones para algunos tipos virales. Una mayor frecuencia de lesiones se asoció a infecciones con carga baja de VPH-16 (ORa: 3.53; IC95%: 1.16 – 10.74), en comparación a mujeres con carga alta de VPH-16, (ORa: 2.63; IC95%: 1.09 – 6.36). En infecciones por VPH-31, la presencia de carga viral alta, se asoció con una menor frecuencia de lesiones (ORa: 0.34; IC95%: 0.15 – 0.78). Conclusiones: La prevalencia tipo-específica de VPH se corresponde con las reportadas a nivel mundial. La asociación entre la carga viral del VPH y la frecuencia de LEI es tipo específica y podría depender de la duración de la infección, altas cargas relacionadas con infecciones transitorias, y bajas cargas con persistentes. Este trabajo contribuye al entendimiento del efecto de la carga viral en la historia natural del CC; sin embargo, estudios prospectivos son necesarios para confirmar estos resultados.

Women's work choices in Kenya: the role of social institutions and household gender attitudes

This study considers the factors that influence women’s work behavior in Kenya. In particular, it examines whether gender attitudes and certain types of social institutions influence the probability of employment or type of employment for women. Using data from the Demographic and Health Survey of 2008–9, we find that religion and ethnicity are significant determinants of women’s employment in Kenya. While personal experience of female genital mutilation is insignificant, spousal age and education differences, as well as marital status (which reflect attitudes both in women’s natal and marital families), are significant determinants of women’s employment choices.

Kvinnlig Könsstympning : Litteraturstudie om praktisk handläggning och komplikationsrisker vid förlossning

Today around 28 000 women originally from countries where FGM is practised, are living in Sweden. Many of them are at childbearing age which means that knowledge about FGM and its consequences is of outmost importance during delivery. The aim of this study is to describe current research on how to manage the delivery, regarding deinfibulation and the following stitching as well as the risk of complications when the labouring woman is mutilated. This review of literature is based on 12 scientific articles published between years 1989 – 2005. Five different databases have been searched with use of a large number of keywords.The review found that no scientific research has been carried out that describes how deinfibulation and following stitching should be managed when the woman is mutilated. All available articles within this area are referring to best practice only. The review also found that the conclusions of the studies are contradictory. The majority, however, show an increased frequency for prolonged labour that could be related to FGM. The three largest studies also show an increased rate of caesarean section among mutilated women. In the few studies that examine haemorrhage, the majorities show an increased tendency to bleed, that could be related to FGM. Several articles emphasize the importance of good routines for deinfibulation to reduce the risk for complications.In summary it can be established that due to methodological problems in many studies, no reliable conclusion can be made that the researched complications exists to a greater extent when the woman is mutilated

Reducing harmful traditional practices in Adjibar, Ethiopia : lessons learned from the Adjibar safe motherhood project

This paper assesses the impact of the Adjibar Safe Motherhood Project and derives lessons of value to future interventions. Amongst the participatory qualitative methods used were 15 group discussions, eight semi-structured interviews, a number of opportunistic informal discussions and observation. The information gathering was complemented by a detailed review of project documents. Field visits for data collection took place over a six day period in March 2005. The project was effective in raising awareness about maternal health, and the social, economic and health consequences of various harmful traditional practices (HTPs). It has also mobilised the community to monitor and report HTPs and has strengthened referral systems for counselling, support and treatment. A number of effective strategies were identified as having contributed to project success. These are presented using the framework offered by the Ottawa Charter for Health Promotion which presents five areas of public health action: developing personal skills; strengthening community action; building healthy public policy; re-orienting health services; and, creating supportive environments. This evaluation contributes to and strengthens the expanding body of literature about effective development practices to reduce HTPs. It demonstrates that addressing HTPs takes time and long term investment; both are necessary to enable better understanding of the social and cultural reasons for HTPs before attempting to address them, and to build the community trust necessary to overcome the natural resistance to challenging such deeply entrenched practices. The project also highlighted the importance of developing a multi pronged strategy based on engagement with a broad range of stakeholders and supportive legislation.

Changing bodies, changing discourses : women's experiences of early menopause

Early menopause has been constructed by discourses of biological determinism as an untimely, but natural, failure of the female body. Medical discourses in particular have interpreted early menopause as a congenital irregularity and a rare anomaly of menopause at midlife. In this thesis I challenge the notion that early menopause is an innate imperfection related only to women’s age. I propose that early menopause is dependent upon the cultural interpretations of individual women and is constituted through the mercurial and multiple discourses of women who have this embodied experience. Moreover, I reveal that early menopause is a contemporary condition and that its location in history is inextricably bound to discourses of risk, naturalism and the self. Further I make the assumption that having an early menopause both affects and is an effect of women’s fertility, sexuality and subjectivity. I have drawn upon a broad range of sources to provide a sociological analysis of early menopause. Literature on early menopause is dominated by positivist discourses, yet many alternate discourses negotiate these influential constructions. I suggest here that the perception of early menopause as a natural fault is merely a construction by medical discourses and does not incorporate the dynamic discourses of early-menopausal women. Moreover, the restriction of early menopause to a genetic female failure excludes the majority of women who have an early menopause through iatrogenisis. This omission occurs through the failure of positivist discourses to accommodate diversity in discourses. Recent sociological and feminist studies have vindicated menopausal women. They have reconstructed menopause through notions of embodiment and have removed the veil of negativity used by the medical sciences to contain menopausal women (Komesaroff, Rothfield and Daly 1997). The visibility of menopausal women, however, remains connected to age. Menopause has been created as a predictable consequence of aging and as such has come to be synonymous with middle age. Nowadays, even men are said to experience menopause at midlife (Carruthers 1996). But early menopause is constituted within the discourses of women who have this experience. Medico-scientific discourses, based upon theories of genetic inevitability, disregard this perspective. Consequently early menopause is subsumed by naturalistic discourses that relate menopause to midlife. Such restraint reflects the unease created by menopause that does not coincide with prescribed life stages. Women's experiences of their changing bodies are largely unheard. Thus, women who have an early menopause are faced with a chasm of ‘cultural non-recognition’ (Fraser 1997). Conjointly with this discursive repression early-menopausal women face social imbalances that are transacted as both cause and consequence of early menopause. In particular the contemporary creation of early menopause is bound to the social and historical location of women as a group. Women are exploited by the institution of medicine, ‘exposure to environmental toxicity’ (Fraser 1997: 11) and commercialization as causes of early menopause. Yet the corporeal effects of practices of risk avoidance (Beck 1993), social practices (Shilling 1993) and Western consumerism (Lupton 1994) fail to be recognized. I address these problematics through a poststructural and feminist critique that assumes moments of commonality among women, while at the same time recognizes shifting and multiple differences (Nicholson 1999). I suggest here that early menopause falls into cultural misrecognition in Fraser's (1997) terms and argue that it is united concurrently with the gender injustice of androcentrism (Fraser 1997: 21). Fraser (1997: 16) suggests that it is only by relating these dual problematics that we are able to make sense of current dilemmas. Thus I have critiqued early menopause through a connection between individual embodied experiences of early menopause and early menopause as a modern phenomenon that is specific to women. I have attempted to unravel these arguments that simultaneously call to ‘... abolish gender differentiation and to valorize gender specificity’ (Fraser 1997: 21) while at the same time acknowledging their interconnectedness. An approach of merely combining women’s discourses with overarching social issues would be inadequate as not only do these problematics intersect but they also can be opposed. As Fraser (1997: 25) notes with her theory, redressing one aspect of cultural or social analysis can further imbalance another. For instance making visible the diversity and uniqueness of individual experiences of early menopause could detract from acknowledging the contemporary construction of early menopause through social inequality. Crucial to this understanding is a destabilizing of the binary construction of differences between the sexes that makes way for a reconstruction of early menopause through ‘sexual slippage’ (Matus 1995). In this thesis I look for a subtlety between the particular and the collective that views early menopause as concurrently a singular and changeable experience as well as imbedded in social practice. I suggest that these concepts are entwined as interactive effects of early menopause. Thus I have analyzed the bivalent problematics of the embodiment and social location of early menopause as imbricated, dynamic and unending discourses. From this perspective I reviewed the literature that was available on early menopause. In Chapter One I look to descriptions of early menopause and note that it has disappeared into a conglomeration of disparate, mostly medical, discourses that are contradictory. Nevertheless medical discourses offer ‘conclusive’ definitions of early menopause that are based on naturalistic views of the body (Shilling 1994). The determinants used are inconsistent and do not include women's discourses of early menopause. Thus, dominant medical discourses obscure women’s embodied experiences of early menopause and ignore the contemporary causes of early menopause. In Chapter Two I examine the causes of early menopause as a way of explaining the disparity between medical discourses and my anecdotal observations of early menopause as a fairly common contemporary occurrence. The relatively recent escalation in gynaecological surgery, especially hysterectomy, appears to account almost single-handedly for early menopause as a current phenomenon. Moreover, the extraordinary number of women who have their uterus removed at hysterectomy can be interpreted as a modern implementation of ancient anxieties. Women's sexuality has been constructed throughout history as problematic and this unease has been translated through women's bodies as dangerous and in need of control (Greer 1992). Thus social concerns which have evolved historically have emerged through the representation of a woman's uterus as an unseen, dark and mysterious risk (Beck 1993). Medical discourses define this risk and are able to negate the so-called dangers of women's sexuality through the surgical removal of their organs. Widespread negotiation of medical discourses is apparent, as hysterectomy in the modern Western world is the most common of all surgical operations (Hufnagel 1989). It is overwhelmingly the most common cause of early menopause as well. I examine also the historical condemnation of infertile women and how this anxiety has been transposed to the modern world through the commercialization of reproduction. Transactions of this social unease can cause early menopause. For instance the medical technology of in-vitro fertilization (I.V.F.) has been offered as a panacea for the infertility of early menopause but, paradoxically, can cause early menopause as well. Conception through technology has been normalized as a viable option for women who are unable to conceive and understandings of I.V.F. have moved into everyday discourse. Medical discourses have constructed fertility as a saleable item and infertile women expect that they can purchase this merchandise. Human eggs have become lucrative commodities that now are available in the market place. Egg ‘donation’ for I.V.F. programs can hasten the attrition rate of eggs and can cause early menopause in some pre-menopausal women (Rowland 1992: 24). Even the recycling of a woman’s uterus supposedly has become a possibility through the transferring of this ‘used’ organ at hysterectomy to a recipient woman who can use the other woman’s uterus as a ‘gestational garage’ (Rogers 1998). In this way women have been disembodied as mechanical systems with inter-changeable body parts and the potentially detrimental consequences of these commercial transactions are ignored. In addition I show how early menopause can be caused by the connection between the self and the social structure. Women's subjectivity is constituted through the cultural discourses available to them and these discourses affect social behaviour (Lupton 1995). For instance smoking and dieting have been identified as causes of early menopause. These activities have been related to the creation of women’s bodies as hetero-sexually desirable and are endemic to young women (Evans-Young 1995). This suggests that cultural causes of early menopause are transactions of sexual politics. Yet there is a paucity of literature that acknowledges the relationship between women’s subjectivity and early menopause. Thus the second chapter exposes a link between sexual politics and causes of early menopause through women's relationships with risk, naturalism and the self. In Chapter Three I deconstruct early menopause through theoretical considerations. I rely on an overarching poststructuralism that embraces the concept of fragmented plural discourses and the subjectivity of menopausal women as a continuous process (Komesaroff 1997: 61). I have woven these variables through broad feminist critiques (Leonard 1997). Through this eclectic approach I hoped to find some loose alignment between the corporeal, ontological and embodied dimensions of early menopause. The recurring themes of sexuality, fertility and subjectivity emerge through deconstructing discourses of sexual difference as immutable and non-negotiable; exposing ‘premature ovarian failure’ as a discursive construction that censures early-menopausal women; and acknowledging the discourses of individual women as unique, diverse and dynamic. I looked to a method of exposing some of these individual discourses and in Chapter Four I describe a critical research process aimed at understanding early menopause as a lived experience. In the remaining chapters I align these ontological arguments with an analysis of the discourses of women who had experienced or were experiencing an early menopause. This section partly relieves the ‘cultural non-recognition’ of the discourses of early-menopausal women. I recorded the narratives of fifty early-menopausal women through in-depth interviews and used this empirical data to direct the study. This data provides the opportunity to understand early menopause as an assortment of embodied experiences. For instance women’s experiences of age at commencement of menopause spanned over three and half decades. They did not reflect the age specifications prescribed by medical discourses. Rather women interpreted their experiences within their own discourses and determined their menopause as early based upon the expectations of their cultural context. Many of the women experienced changes attributed to menopause at midlife. It was not these changes that were significant to early-menopausal women it was how each woman translated these changes that provided meanings of early menopause. In Chapter Five I introduce the women through a table that connects the varying experiences of each woman. This profile shows that, in the main, the women’s experiences of early menopause were unexpected. I suggest that this is due to the disparity between early-menopausal women’s experiences and the current age and social norms of menopause. By bracketing the women into cohorts patterns emerged displaying differences between women who had menopause in their teens, twenties, thirties and forties. Adolescent women had intense feelings of abnormality and despair. Women who were in their twenties were less devastated by menopause than the younger women but described their sexuality and self-identity as changing. And although some women in their thirties were shocked or dismayed to have an early menopause others were ambivalent or happy. These women also described their sexuality and self-identity through changing discourses. A number of the women who were in their forties said that they were ‘too young for the menopause’ but were far less despondent than the younger women. It seemed that the greater the distance between age norms and social norms the more negatively women responded. Age norms that determine the social norms of women's lives through a ‘biological clock’ are constructed to reflect social values. But age is a social construction that changes over time. Thus it would appear that women’s changing bodies and changing discourses of early menopause are in the process of recreating age and social norms around menopause. In Chapter Six I draw upon women’s narratives that describe a connection between early menopause and sexuality. Yet the respondents were not unified in their constructions of sexuality. For instance a number of the women rejected the containment of their sexuality as absolute and defined in terms of bi-lateral hetero-sexual opposition. The discourses of these women constructed their sexuality as continuously flexible. Some early-menopausal women described this sexual mobility as an equivocal relationship between their sexuality, reproductive capacity and female organs. Other women articulated their sexuality as vacillating, ambiguous and unrepresentative of the so-called ‘true woman’. Several felt that they were not meant to have female reproductive organs at all. Nearly one third of the women had had their uterus removed at hysterectomy and the reproductive organs of two women were rudimentary. Women’s narratives showed that the social value of fertility influences constructions of early menopause. In Chapter Seven I record the contrast between the poignant responses of women who wished to have a baby of their own and other women who resisted discourses that entwine reproductivity with being a woman. For instance some women negotiated fertility through economic discourses of consumerism with the expectation that they could purchase conception as a commodity. Other women welcomed their early menopause as freedom from contraceptive concerns and others had no interest in reproduction at all. Thus discord arose through discourses that problematize early-menopausal women as non-reproductive and discourses that value variability. In addition many of the women’s accounts constructed their subjectivity as mobile, challenging the notion that discourses of the self are immutable. Chapter Eight presents narratives which suggest that the subjectivity of many women was altered continuously by early menopause. Yet some of the women rejected the construction of their subjectivity as unfluctuating. These contradictions reflect the uncertainties of the contemporary world. Nevertheless most respondents found that the tethering of menopause to constructions of midlife was incongruous with their own experiences. Many women refused to accept the label of social redundancy attached to middle-aged women. They moved their subjectivity beyond the reproductive body to a shifting and tractable identity of the self. This thesis demonstrates that the medical construction of early menopause as a rare and natural female flaw varies from women's experiences which suggest that early menopause is common and discursively constructed. This disparity has occurred through the privilege placed upon the construction of bodies as immutable and sexually static. This privileging has obscured the multi-dimensional causes of early menopause and given preference to a mono-causal theory. By exposing the variety of causes of early menopause the medical construction of women through a universal and unalterable body of reproduction is challenged. Moreover, women's discourses of early menopause demonstrate that the medical reduction of early menopause to a spontaneous bio-chemical malfunction has ignored the volatility of women’s embodied experiences. Women experience early menopause variously and through mercurial discourses. I suggest here that women's discourses of their experiences of early menopause reflect recurring and restructuring philosophical quandaries of fertility, sexuality and subjectivity. While there can be no representative claims made from this thesis it contributes to an understanding of the embodied experiences of early menopause. It provides an understanding of the creation of early menopause through social practices and goes part way to redressing the problematics of what Fraser terms ‘cultural non-recognition’. But, more importantly, it acknowledges early menopause as a variety of experiences where women interpret their changing bodies through changing discourses.
