'Someone to welcome you home' : Infertility, medicines and the Sukuma-Nyamwezi

This study Someone to Welcome you home: Infertility, medicines and the Sukuma-Nyamwezi , looks into the change in the cosmological ideology of the Sukuma-Nyamwezi of Tanzania and into the consequences of this change as expressed through cultural practices connected to female infertility. This analysis is based on 15 months of fieldwork in Isaka, in the Shinyanga area. In this area the birth rate is high and at the same time infertility is a problem for individual women. The attitudes connected to fertility and the attempts to control fertility provide a window onto social and cultural changes in the area. Even though the practices connected to fertility seem to be individualized the problem of individual women - the discourse surrounding fertility is concerned with higher cosmological levels. The traditional cosmology emphasized the centrality of the chief as the source of well-being. He was responsible for rain and the fertility of the land and, thus, for the well-being of the whole society. The holistic cosmology was hierarchical and the ritual practices connected to chiefship which dealt with the whole of the society were recursively applied at the lower levels of hierarchy, in the relationships between individuals. As on consequence of changes in the political system, the chiefship was legally abolished in the early years of Independence. However, the holistic ideology, which was the basis of the chiefship, did not disappear and instead acquired new forms. It is argued that in African societies the common efflorence of diviner-healers and witchcraft can be a consequence of the change in the relationship between the social reality and the cosmological ideology. In the Africanist research the increase in the numbers of diviner-healers and witchcraft is usually seen as a consequence of individualism and modernization. In this research, however, it is seen as an altered form of holism, as a consequence of which the hierarchical relations between women and men have changed. Because of this, the present-day practices connected to reproduction pay special attention to the control of women s sexuality.

Long-term outcome and extraintestinal manifestations in congenital chloride diarrhea

The rare autosomal recessive disease congenital chloride diarrhea (CLD) is caused by mutations in the solute carrier family 26 member 3 (SLC26A3) gene on chromosome 7q22.3-31.1. SLC26A3 encodes for an apical epithelial chloride-bicarbonate exchanger, the intestinal loss of which leads to profuse chloride-rich diarrhea, and a tendency to hypochloremic and hypokalemic metabolic alkalosis. Although untreated CLD is usually lethal in early infancy, the development of salt substitution therapy with NaCl and KCl in the late 1960s made the disease treatable. While the salt substitution allows normal childhood growth and development in CLD, data on long-term outcome have remained unclarified. One of the world s highest incidences of CLD 1:30 000 to 1:40 000 occurs in Finland, and CLD is part of the Finnish disease heritage. We utilized a unique sample of Finnish patients to characterize the long-term outcome of CLD. Another purpose of this study was to search for novel manifestations of CLD based on the extraintestinal expression of the SLC26A3 gene. This study on a sample of 36 patients (ages 10-38) shows that the long-term outcome of treated CLD is favorable. In untreated or poorly treated cases, however, chronic contraction and metabolic imbalance may lead to renal injury and even to renal transplantation. Our results demonstrate a low-level expression of SLC26A3 in the human kidney. Although SLC26A3 may play a minor role in homeostasis, post-transplant recurrence of renal changes shows the unlikelihood of direct transporter modulation in the pathogenesis of CLD-related renal injury. Options to resolve the diarrheal symptoms of CLD have been limited. Unfortunately, our pilot trial indicated the inefficacy of oral butyrate as well. This study reveals novel manifestations of CLD. These include an increased risk for hyperuricemia, inguinal hernias, and probably for intestinal inflammation. The most notable finding of this study is CLD-associated male subfertility. This involves a low concentration of poorly motile spermatozoa with abnormal morphology, high seminal plasma chloride with a low pH, and a tendency to form spermatoceles. That SLC26A3 immunoexpression appeared at multiple sites of the male reproductive tract in part together with the main interacting proteins cystic fibrosis transmembrane conductance regulator (CFTR) and sodium-hydrogen exchanger 3 (NHE3) suggests novel sites for the cooperation of these proteins. As evidence of the cooperation, defects occurring in any of these transporters are associated with reduced male fertility. Together with a finding of high sweat chloride in CLD, this study provides novel data on extraintestinal actions of the SLC26A3 gene both in the male reproductive tract and in the sweat gland. These results provide the basis for future studies regarding the role of SLC26A3 in different tissues, especially in the male reproductive tract. Fortunately, normal spermatogenesis in CLD is likely to make artificial reproductive technologies to treat infertility and even make unassisted reproduction possible.

Outcome of singleton pregnancy after assisted reproductive treatment

Singleton pregnancies achieved by means of assisted reproductive treatment (ART) are associated with increased obstetric and neonatal risks in comparison with spontaneously conceived singleton pregnancies. The impact of infertility- and treatment-related factors on these risks is not properly understood. In addition, the psychological effects of infertility and its treatment on the experience of pregnancy have scarcely been studied. Thus, the aim of the present study was to evaluate the importance of infertility- and treatment-related factors on prediction of pregnancy outcome, obstetric and neonatal risks, fear-of-childbirth and pregnancy-related anxiety. The subjects consisted of infertile women who achieved a singleton pregnancy by means of in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI). The control groups comprised spontaneously conceiving women with singleton gestations. Early pregnancy outcome was assessed by means of assay of serum human chorionic gonadoptrophin (hCG) in single samples. Other outcome data were collected from patient records, national Health Registers and via prospective questionnaire surveys. Viable pregnancies were associated with significantly higher serum hCG levels 12 days after embryo transfer than non-viable pregnancies. Among singleton pregnancies, aetiological subgroup, treatment type or the number of transferred embryos did not impair the predictive value of single hCG assessment. According to the register-based data, age-, parity- and socioeconomic status- adjusted risks of gestational hypertension, preterm contractions and placenta praevia were more frequent in the ART pregnancies than in the control pregnancies. Significantly higher rates of induction of delivery and Caesarean section occurred in the ART group than in the control group. The risks of preterm birth and low birth weight (LBW) were increased after ART pregnancy. Duration or aetiology of infertility, treatment type (fresh or frozen IVF or ICSI) or rank of treatment did not contribute to the risks of preterm birth or LBW. In addition, the risks of preterm birth and LBW remained elevated in spite of of the number of transferred embryos. Although mean duration of pregnancy was shorter and mean birth weight lower in the ART pregnancies than in the control pregnancies, these differences were hardly of clinical significance. Fear-of-childbirth and pregnancy-related anxiety were equally common to women conceiving by means of ART, or spontaneously. Partnership of five to ten years appeared to be protective as regards severe fear-of-childbirth, whereas long preceding infertility (≥ seven years) had the opposite effect. In conclusion, an early hCG assessment maintained its good predictive value regardless of infertility- or patient-related factors. Further, we did not recognise any infertility- or patient-related factors that would expose infertile women to increased obstetric or neonatal risks. However, a long period of infertility was associated with severe fear-of-childbirth.

Transition to parenthood after assisted reproductive treatment: Follow-up study of singleton pregnancies

Infertility treatments are relatively easily available in most Western countries today, but the psychological consequences of these high-tech treatments have scarcely been addressed. The purpose of this controlled longitudinal study was to explore the early environment of the infant born by assisted reproductive treatment (ART). We focused on the parents mental well-being, marital relations and experience of parenting. In addition to this, we assessed parent child interaction and parents mental representations of their child after long-standing infertility and several unsuccessful ART attempts. The subjects were infertile couples who achieved a singleton pregnancy by in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). The control group comprised of spontaneously conceiving couples with singleton pregnancies. ART women showed fewer depressive symptoms than controls during pregnancy and after delivery, but the difference vanished by the end of the child s first year. ART men consistently had lower levels of anxiety symptoms, sleeping difficulties, and social dysfunction than control men. Control women experienced a decrease in dyadic consensus during the child s first year, which did not happen among ART women. After the child was born, ART men reported a higher level of sexual affection compared with control men. Psychic symptoms and stressful life events were differently related to marital relations in ART and control groups. The parenting experiences of ART mothers were in general at a higher level, compared with controls, and they changed in a positive direction during the child s first year. Fathering experiences were at the same level in both groups, and they changed positively in both groups by the end of the child s first year. The parenting experiences of ART mothers and fathers were more resilient to certain child-related stressors than those of control group. Both mothers and fathers with long-term infertility showed more sensitive behaviour with their child in toddler-age than in infancy. Correspondingly, children s cooperation increased. Mothers often mentioned a fear of miscarriage and difficulty in creating representations of the child during pregnancy. Descriptions of the infants were mainly rich, vivid and loaded with positive features. In conclusion, ART parents in general seem to adapt well to the transition to parenthood. Former infertility and ART do not seem to constitute a risk for parents mental health, marital relations or experience of parenting. Even longstanding infertility with several unsuccessful treatment attempts did not create a risk as regards parenting behaviour or parents mental representations of their child. In this group, however, women were found to have fear for losing the child and difficulty in creating representations of the child during pregnancy, which in some cases may indicate need for psychosocial support. Even though our results are encouraging, infertility and infertility treatments are generally considered as a stressful experience. It is a challenge for health authorities to recognize those couples who need professional help to overcome the distressing experiences of infertility and ART.

Biovalta, toiseus ja naisten toimijuus hedelmöityshoidoissa

Biopower, Otherness and Women's Agency in Assisted Reproduction. This sociological study analyses how, why and with what kind of consequences assisted reproductive technologies (ART) have become the primary technology for governing infertility in Finland both on the level of individuals and society. The phenomenon is construed as one the strategies of the Focaultian biopower since ART are political techniques of the beginning of life par excellence, as they are used to prepare the bodies of certain types of women to create certain kind of life, i.e. certain kind of children. Moreover, ART are interpreted to be gendered control techniques with which the pure, and at the same time prevailing, social order symbolised by a female body is maintained by naming and excluding otherness, unsuitable mother candidates and children. Finally, it is considered how the agency, subjectivity, of women experiencing infertility and seeking treatment appears in the prevailing context of ART. The introduction of IVF-based reproductive technologies to Finland and the treatment practices of the early 1990s have been studied on the basis of a clinic questionnaire, medical doctor interviews and articles of the Medical Journal Duodecim from 1969 to 2000. Opinions on the method of the treatment providers were studied by conducting a theme interview with fertilisation doctors in 1993. Experiences of women who have received treatment or experienced infertility were studied by means of a survey in 1994 and by analysing the content of messages in an online discussion forum in 2000. On the basis of the medical doctor interviews, significant criterion for choosing mother candidates turned out to be her vitality and her mental and physical health, which are considered prerequisites for a vitality of the child to be born. The hierarchies concerning children became evident. While people normally make their children on their own, this is what people experiencing infertility are trying to do as well. In the era of ART, the primary child is genetically the parents' own child, a secondary option for Finnish parents is a genetically Finnish child conceived by donated Finnish gametes or embryos and the last option is an adopted child of foreign origin. Women's agency mainly appears in their way of using ART as a technology of the self for self-control on one's own nature, which helps them to prepare their bodies in order to become pregnant in co-operation with a fertilisation doctor. Women's creative free agency exceeding governance appeared as a distinctive use of language with which they created shared meaning for their infertility experience, their own individual and group identity and distinctive reality. ART are very political techniques as they have a possibility to change the methods of having children and to shape life. Therefore, further sociological research on them is important and needed. Key words: practises of assisted reproduction, women's agency, biopower, vital politics of the beginning of life, otherness

Impaired spermatogenesis in Finnish boars and bulls

Maintenance of breeding efficiency and high semen quality is essential for reproductive success in farm animals. Early recognition of possible inheritable factors causing infertility requires constant attention. This thesis focuses on describing different manifestations of impaired spermatogenesis, their impact on fertility and partly also their incidence in populations. The reasons for spermatogenic failure are various. An interruption of germ cell differentiation, spermatogenic arrest, can lead to infertility. The incidence of azoospermia was investigated in the 1996 2005 survey of Finnish AI and farm breeding boars. We focused on the diagnosis, testicular morphometry and the possible reasons for the condition. The incidence of azoospermia was significantly higher in Yorkshire boars than in the Landrace breed. The most common diagnosis in Yorkshire boars was germ cell arrest at the primary spermatocyte level. The second most frequent diagnosis in Yorkshire boars was segmental aplasia of the Wolffian ducts with idiopathic epididymal obstruction. Other reasons for azoospermia were infrequent. In the second study we investigated the incidence of two relatively well-defined specific sperm defects in Finnish Yorkshire and Landrace boars during the same survey, the immotile short-tail sperm (ISTS) defect and the knobbed acrosome (KA) defect. In the Finnish Yorkshire boars the inherited ISTS defect, and the probably inherited KA defect, were important causes of infertility during 1996 2005. The ISTS defect was found in 7.6% and the KA defect in 0.8% of the Yorkshire boars. No Landrace boars were diagnosed with either of these two defects. In the third study we described a new sterilizing sperm defect in an oligoasthenoterazoospermic bull. Because of its morphological characteristics this defect was termed the multinuclear-multiflagellar sperm (MNMFS) defect. The number of Sertoli cells in the seminiferous tubuli was highly increased in the MNMFS bull compared with the number in normal bulls. In the following two studies we used a combined approach of fluorescence in situ hybridization (FISH), flow cytometry and morphometric studies to provide information on the cytogenetic background of macrocephalic bull spermatozoa. We described cellular features of diploid spermatozoa and compared the failures in the first and second meiotic divisions. In the last study we describe how the transplantation of testicular cells was used to determine whether spermatogonia derived from donor animals are able to colonize and produce motile spermatozoa in immune-competent unrelated boars suffering the ISTS defect. Transplantation resulted in complete focal spermatogenesis, indicated by the appearance of motile spermatozoa and confirmed by genotyping.
