Efficacy of psychological interventions for sexual dysfunction: a systematic review and meta-analysis

Sexual dysfunction is highly prevalent in the general population and associated with psychological distress and impaired sexual satisfaction. Psychological interventions are promising treatment options, as sexual dysfunction is frequently caused by and deteriorates because of psychological factors. However, research into the efficacy of psychological interventions is rather scarce and an up-to-date review of outcome studies is currently lacking. Therefore, we conducted a systematic review and meta-analysis of all available studies from 1980 to 2009 to examine the efficacy of psychological interventions for patients with sexual dysfunction. A total of 20 randomized controlled studies comparing a psychological intervention with a wait-list were included in the meta-analysis. The overall post-treatment effect size for symptom severity was d = 0.58 (95% CI: 0.40 to 0.77) and for sexual satisfaction d = 0.47 (95% CI: 0.27 to 0.70). Psychological interventions were shown to especially improve symptom severity for women with Hypoactive Sexual Desire Disorder and orgasmic disorder. Our systematic review of 14 studies comparing at least two active interventions head-to-head revealed that very few comparative studies are available with large variability in effect sizes across studies (d between -0.69 and 2.29 for symptom severity and -0.56 and 14.02 for sexual satisfaction). In conclusion, psychological interventions are effective treatment options for sexual dysfunction. However, evidence varies considerably across single disorders. Good evidence exists to date for female hypoactive sexual desire disorder and female orgasmic disorder. Further research is needed on psychological interventions for other sexual dysfunctions, their long-term and comparative effects.

Male and female sexual function after surgical repair of female organ prolapse

INTRODUCTION: Few data are available referring to male and female sexual function after prolapse repair of symptomatic pelvic organ. AIM: Primary aim of this study is to determine the male and female sexual function before and after surgery for pelvic organ prolapse. MAIN OUTCOME MEASURES: We used the Female Sexual Function Index (FSFI) questionnaire for female patients and for their male partners the Brief Male Sexual Inventory (BMSI) as measurement of sexual function. METHODS: We included sexually active heterosexual couples that were referred to the Department of Urogynaecology because of symptomatic cystocele, rectocele or vault descent. For cystoceles, anterior repair was performed, for rectoceles posterior repair, and for vault descent sacrospinous ligament fixation. FSFI and BMSI questionnaires were distributed before and after pelvic organ surgery and 4 months after. Female clinical examination assessing the degree of prolapse was performed before and 6 weeks after surgery. RESULTS: A full data set of 70 female questionnaires and 64 male questionnaires could be evaluated. Two cases of female de novo dyspareunia occurred. In women, FSFI scores improved significantly in the domains desire, arousal, lubrication, overall satisfaction, and particularly pain. Orgasm remained unchanged. In men, interest, sexual drive, and overall satisfaction improved significantly. Erection, ejaculatory function, and orgasm remained unchanged. Despite remaining unchanged, erection, strength of erection, ejaculation, and orgasm were not considered problems anymore compared to preoperative BMSI scores. CONCLUSION: Surgery for pelvic organ prolapse improves male and female sexual function in some domains but not in all.

Sexual dysfunction in multiple sclerosis

Multiple sclerosis is a chronic disease that commonly affects young adults who may be sexually active. Sexual dysfunction is a significant, but often underestimated, symptom of multiple sclerosis, affecting 50-90% of men and 40-80% of women. The types of sexual dysfunction can be categorized in terms of the normal sexual response cycle: sexual interest/desire dysfunction (reduced libido), sexual arousal dysfunction (including erectile dysfunction) and ejaculatory and orgasmic dysfunction. Sexual dysfunction may not only be due to lesions affecting the neural pathways involved in physiological function (primary dysfunction), but also result from general physical disabilities (secondary dysfunction) or psychological and emotional issues (tertiary dysfunction). Comprehensive management should address all these possible contributing problems. Specific pharmacotherapy is only currently available for erectile dysfunction. This review summarizes the available information about sexual dysfunction in men and women with multiple sclerosis.

Sexual function after sacrospinous fixation for vaginal vault prolapse: bad or mad?

BACKGROUND: The main indication for sacrospinous ligament suspension is to correct either total procidentia, a posthysterectomy vaginal vault prolapse with an associated weak cardinal uterosacral ligament complex, or a posthysterectomy enterocele. This study aimed to evaluate sexual function and anatomic outcome for patients after sacrospinous ligament suspension. METHODS: For this study, 52 patients who had undergone sacrospinous ligament fixation during the preceding 5 years were asked to complete the Female Sexual Function Index (FSFI) questionnaire. The patients were vaginally examined using the ICS POP score, and the results were compared with their preoperative status. For statistical analysis, GraphPad for Windows, version 4.0, was used. RESULTS: The 52 patients were examined during a follow-up period of 38 months. No major intraoperative complications were noted. Recurrence of symptomatic apical descent was noted in 6% of the patients and de novo prolapse in 13.5%. Only one patient was symptomatic. Three patients experienced de novo dyspareunia, which resolved in two cases after stitch removal. Sexual function was good, rating higher than three points for each of the domains including satisfaction, lubrication, desire, orgasm, and pain. CONCLUSION: Sacrospinous ligament fixation still is a valuable option for the treatment of vaginal vault prolapse. Sexual function is satisfactory, with few cases of de novo dyspareunia.

Correction of erosion after suburethral sling insertion for stress incontinence: results and related sexual function

BACKGROUND: Suburethral slings are commonly used for the surgical treatment of female stress incontinence; occasionally they can cause erosion and dyspareunia. OBJECTIVES: The primary aim of this study is to determine the outcome after reclosure of the vaginal epithelium for suburethral sling erosion. Sexual function was assessed before and after intervention using the Female Sexual Function Index (FSFI) questionnaire. DESIGN, SETTING, AND PARTICIPANTS: This was a prospective case-controlled study in which, between December 2005 and December 2007, we included patients who were referred to the Department of Urogynaecology because of vaginal erosion after suburethral sling insertion for urinary stress incontinence. For evaluation of sexual function, all patients filled in an FSFI questionnaire before intervention and at follow-up. All patients underwent gynaecological examination including colposcopy, and the site and size of the defect were noted. INTERVENTION: The edge of the vaginal epithelium was trimmed, mobilized, and closed with interrupted vertical Vicryl mattress sutures in a single layer. MEASUREMENTS: FSFI questionnaire and clinical findings. RESULTS AND LIMITATIONS: Twenty-one patients were included in the study. Eighteen patients with larger defects were operated on, and three defects healed after topical application of estrogen cream. In 16 patients, the defect had healed at follow-up; two patients with persisting defects were brought back to surgery and the procedure was repeated, paying particular attention to tension-free adaptation of vaginal tissue. In one patient, partial sling removal was performed after the second failed intervention. The domains of desire (p<0.0001), arousal (p<0.0003), lubrication (p<0.0001), satisfaction (p<0.0130), and pain (p<0.0001) improved significantly. Orgasm remained unchanged (p=0.4130; all two-tailed t-test). CONCLUSION: Suburethral erosion can be treated effectively by resuturing. Sexual function is improved in regard to desire, arousal, lubrication, satisfaction, and pain, but not orgasm. In septic patients and patients with a history of radiation, grossly infected tissue, or severe pain, excision of the mesh needs to be considered.

Sexual and organ function in patients with symptomatic prolapse: are pessaries helpful?

OBJECTIVE: To evaluate quality of life and pelvic organ and sexual function before and during pessary use in patients with symptomatic pelvic organ prolapse and to determine reasons which lead to cessation of pessary use. DESIGN: Prospective observational study. SETTING: Tertiary referral center. PATIENT(S): Patients with symptomatic stage II or more prolapse of the anterior, posterior, or apical vaginal wall with or without uterus were included in this study. INTERVENTION(S): We used the Female Sexual Function Index questionnaire and the Sheffield prolapse questionnaire. For quality of life we used the King's Health Questionnaire. MAIN OUTCOME MEASURE(S): Main outcome measures were quality of life and sexual and pelvic organ function. RESULT(S): A total of 73 women participated in this study; 31 were sexually active. Desire, lubrication, and sexual satisfaction showed statistically significant improvement, and orgasm remained unchanged. Statistically significant improvement in the feeling of bulge occurred during therapy, stool outlet problems were significantly improved, overactive bladder symptoms were significantly better, and pessaries did not significantly alter incontinence. CONCLUSION(S): Pessaries have been shown to be a viable noninvasive treatment for pelvic organ prolapse improving organ and sexual function as well as general wellbeing.

Sexual function after vaginal and abdominal fistula repair

OBJECTIVE The purpose of this study was to compare clinical outcomes and sexual function between transvaginal and transabdominal repairs of vesicovaginal fistulae (VVF). STUDY DESIGN Participants (99 women with VVF at a tertiary referral center) were treated with urinary catheterization for 12 weeks and, if the procedure was unsuccessful, underwent repair either the transvaginal (Latzko) or transabdominal technique. Objective clinical parameters were analyzed; subjective outcomes were recorded prospectively at the 6-month follow-up examination with the use of the female sexual function index to evaluate sexual function and the visual analogue scale to measure general disturbance by the fistula. RESULTS After bladder drainage for 12 weeks, 8 patients had spontaneous fistula closure. Demographic variables were similar in the transvaginal (n = 60) and transabdominal (n = 31) repair groups. The transvaginal procedure showed significantly shorter operation times, less blood loss, and shorter hospital stay. Continence rates 6 months after surgery were 82% (transvaginal) and 90% (transabdominal). Sexual function in the 64 sexually active patients was significantly improved, and overall disturbance by the fistula was reduced with both operative techniques. Neither surgical intervention was superior to the other regarding any domain of sexual function or visual analog scale. CONCLUSION Fistula repair improves sexual function and quality of life with no difference attributable to surgical route. Given this and that operating time, blood loss and length of stay are less with the transvaginal approach, the transvaginal approach is preferred in VVF repair if fistula and patient characteristics are suitable.

Sexual health in hematopoietic stem cell transplant recipients

Hematopoietic stem cell transplantation (HSCT) plays a central role in patients with malignant and, increasingly, nonmalignant conditions. As the number of transplants increases and the survival rate improves, long-term complications are important to recognize and treat to maintain quality of life. Sexual dysfunction is a commonly described but relatively often underestimated complication after HSCT. Conditioning regimens, generalized or genital graft-versus-host disease, medications, and cardiovascular complications as well as psychosocial problems are known to contribute significantly to physical and psychological sexual dysfunction. Moreover, it is often a difficult topic for patients, their significant others, and health care providers to discuss. Early recognition and management of sexual dysfunction after HSCT can lead to improved quality of life and outcomes for patients and their partners. This review focuses on the risk factors for and treatment of sexual dysfunction after transplantation and provides guidance concerning how to approach and manage a patient with sexual dysfunction after HSCT.

Internal iliac artery embolization before endovascular repair of aortoiliac aneurysms with a nitinol vascular occlusion plug

PURPOSE: To evaluate the acute and midterm effectiveness of a novel vascular occlusion device for embolization of the internal iliac artery (IIA) before endovascular repair of aortoiliac aneurysms. MATERIALS AND METHODS: Between March 2005 and April 2006, nine men (mean age, 75 years +/- 5; range, 66-83 y) with aortoiliac aneurysms underwent bifurcated endovascular stent-graft procedures. All these patients were referred specifically for embolization. Pre- and perioperatively, eight patients underwent unilateral embolization and one underwent bilateral embolization of the IIA to prevent type II endoleak. Via a contralateral femoral approach with a 6-F or 8-F sheath, the embolization procedure was performed with an Amplatzer Vascular Plug, a self-expandable cylindrical device consisting of a nitinol-based wire mesh. Technical success, clinical outcome, and complications were evaluated. Follow-up at 3, 6, and 12 months was performed with clinical and radiologic examinations. RESULTS: IIA embolization was technically successful in all cases and no procedure-related complications occurred. Imaging at discharge and at 3-, 6-, or 12-month follow-up was accomplished in all nine patients. Control computed tomography and magnetic resonance angiography did not reveal retrograde perfusion of the aneurysmal sac, ie, type II endoleak. Three of nine patients (33.3%) reported symptoms of buttock claudication that did not resolve completely. Clinical symptoms such as bowel ischemia or sexual dysfunction were not observed. CONCLUSIONS: The midterm results of this study suggest that preoperative IIA embolization with a nitinol vascular occlusion plug during endovascular treatment of aortoiliac aneurysms is safe and effective.

Impact of environmental estrogens on Yfish considering the diversity of estrogen signaling.

Research on endocrine disruption in fish has been dominated by studies on estrogen-active compounds which act as mimics of the natural estrogen, 17β-estradiol (E2), and generally exert their biological actions by binding to and activation of estrogen receptors (ERs). Estrogens play central roles in reproductive physiology and regulate (female) sexual differentiation. In line with this, most adverse effects reported for fish exposed to environmental estrogens relate to sexual differentiation and reproduction. E2, however, utilizes a variety of signaling mechanisms, has multifaceted functions and targets, and therefore the toxicological and ecological effects of environmental estrogens in fish will extend beyond those associated with the reproduction. This review first describes the diversity of estrogen receptor signaling in fish, including both genomic and non-genomic mechanisms, and receptor crosstalk. It then considers the range of non-reproductive physiological processes in fish that are known to be responsive to estrogens, including sensory systems, the brain, the immune system, growth, specifically through the growth hormone/insulin-like growth factor system, and osmoregulation. The diversity in estrogen responses between fish species is then addressed, framed within evolutionary and ecological contexts, and we make assessments on their relevance for toxicological sensitivity as well as ecological vulnerability. The diversity of estrogen actions raises questions whether current risk assessment strategies, which focus on reproductive endpoints, and a few model fish species only, are protective of the wider potential health effects of estrogens. Available - although limited - evidence nevertheless suggests that quantitative environmental threshold concentrations for environmental protection derived from reproductive tests with model fish species are protective for non-reproductive effects as well. The diversity of actions of estrogens across divergent physiological systems, however, may lead to and underestimation of impacts on fish populations as their effects are generally considered on one functional process only and this may underrepresent the impact on the different physiological processes collectively.

Swiss Feline Cancer Registry: A Retrospective Study of the Occurrence of Tumours in Cats in Switzerland from 1965 to 2008

Cancer is one of the leading causes of death in companion animals. Information on the epidemiology of cancer is instrumental for veterinary practitioners in patient management; however, spontaneously arising tumours in companion animals also resemble those in man and can provide useful data in combating cancer. Veterinary cancer registries for cats are few in number and have often remained short-lived. This paper presents a retrospective study of tumours in cats in Switzerland from 1965 to 2008. Tumour diagnoses were coded according to topographical and morphological keys of the International Classification of Oncology for Humans (ICD-O-3). Correlations between breed, sex and age were then examined using a multiple logistic regression model. A total of 18,375 tumours were diagnosed in 51,322 cats. Of these, 14,759 (80.3%) tumours were malignant. Several breeds had significantly lower odds ratios for developing a tumour compared with European shorthair cats. The odds of a cat developing a tumour increased with age, up to the age of 16 years, and female cats had higher risk of developing a tumour compared with male cats. Skin (4,970; 27.05%) was the most frequent location for tumours, followed by connective tissue (3,498; 19.04%), unknown location (2,532; 13.78%) and female sexual organs (1,564; 8.51%). The most common tumour types were epithelial tumours (7,913; 43.06%), mesenchymal tumours (5,142; 27.98%) and lymphoid tumours (3,911; 21.28%).

No evidence for a genetic association between female mating preference and male secondary sexual trait in a Lake Victoria cichlid fish

Sexual selection by female mating preference for male nuptial coloration has been suggested as a driving force in the rapid speciation of Lake Victoria cichlid fish. This process could have been facilitated or accelerated by genetic associations between female preference loci and male coloration loci. Preferences, as well as coloration, are heritable traits and are probably determined by more than one gene. However, little is known about potential genetic associations between these traits. In turbid water, we found a population that is variable in male nuptial coloration from blue to yellow to red. Males at the extreme ends of the phenotype distribution resemble a reproductively isolated species pair in clear water that has diverged into one species with blue-grey mates and one species with bright red males. Females of the turbid water population vary in mating preference coinciding with the male phenotype distribution. For the current study, these females were mated to blue males. We measured the coloration of the sires and male offspring. Parents-offspring regression showed that the sires did not affect male offspring coloration, which confirms earlier findings that the blue species breeds true. In contrast, male offspring coloration was determined by the identity of the dams, which suggests that there is heritable variation in male color genes between females. However, we found that mating preferences of the dams were not correlated with male offspring coloration. Thus, there is no evidence for strong genetic linkage between mating preference and the preferred trait in this population [Current Zoology 56 (1): 57-64 2010].

Sequential female assessment drives complex sexual selection on bower shape in a cichlid fish

In many animals, sexual selection on male traits results from female mate choice decisions made during a sequence of courtship behaviors. We use a bower-building cichlid fish, Nyassachromis cf. microcephalus, to show how applying standard selection analysis to data on sequential female assessment provides new insights into sexual selection by mate choice. We first show that the cumulative selection differentials confirm previous results suggesting female choice favors males holding large volcano-shaped sand bowers. The sequential assessment analysis reveals these cumulative differentials are the result of selection acting on different bower dimensions during the courtship sequence; females choose to follow males courting from tall bowers, but choose to engage in premating circling with males holding bowers with large diameter platforms. The approach we present extends standard selection analysis by partitioning the variances of increasingly accurate estimates of male reproductive fitness and is applicable to systems in which sequential female assessment drives sexual selection on male traits.

Out of Eastern Africa: defibulation and sexual function in woman with female genital mutilation

Female genital mutilation (FGM) is defined by the World Health Organization (WHO) as all procedures that involve partial or total removal of the female external genitalia and/or injury to the female genital organs for cultural or any other non-therapeutic reasons.
