Sexual functioning, sexual esteem, genital self-image and psychological and relational functioning in women with Mayer-Rokitansky-Küster-Hauser syndrome: a case-control study

STUDY QUESTION

Do sexual functioning, sexual esteem, genital self-image and psychological and relational functioning in women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome differ from a comparison group of women without the condition?

SUMMARY ANSWER

In comparison to controls, women with MRKH with a non-surgically or surgically created neovagina did not differ in psychological and relational functioning but reported lower sexual esteem and more negative genital self-image, intercourse-related pain, clinically relevant sexual distress and sexual dysfunction, with sexual esteem levels strongly associated with sexual distress and sexual dysfunction.

WHAT IS KNOWN ALREADY

Studies on sexual functioning measured with standardized questionnaires in women with MRKH syndrome compared with women without the condition have yielded contradictory results. Factors associated with sexual functioning in this patient population have rarely been investigated.

STUDY DESIGN, SIZE, DURATION

Between November 2015 and May 2017, 54 women with MRKH syndrome with a neovagina and 79 age-matched healthy women without the condition were enrolled in this case-control study.

PARTICIPANTS/MATERIALS, SETTING, METHODS

All participants had to be at least 18-years old and had to live in a steady heterosexual relationship. Women with MRKH syndrome were asked to participate by their (former) gynecologists at three university hospitals and by MRKH peer support group. Controls were recruited via advertisement in local newspapers and social media. Standardized questionnaires were administered to assess sexual functioning, sexual esteem, genital self-image and psychological and relational functioning.

MAIN RESULTS AND THE ROLE OF CHANCE

Women with MRKH syndrome with a surgically or non-surgically created neovagina reported significantly more pain during intercourse (P < 0.05, d = 0.5), but did not differ in overall sexual functioning from control women. More women with MRKH syndrome reported clinically relevant sexuality-related distress (P < 0.05, odds ratio (OR): 2.756, 95% CI 1.219-6.232) and suffered a sexual dysfunction (P < 0.05, OR: 2.654, 95% CI: 1.088-6.471) in comparison with controls. MRKH women scored significantly lower on the sexual esteem scale (SES) (P < 0.01, d = 0.5) and the female genital self-image scale (FGSIS) (P < 0.01, d = 0.6) than controls. No significant differences were found between the two groups regarding psychological distress, anxiety and depression, global self-esteem and relational dissatisfaction. Sexual esteem was significantly associated with the presence of clinically relevant sexual distress (ß = 0.455, P = 0.001) and suffering a sexual dysfunction (ß = 0.554, P = 0.001) and explained, respectively, 40% and 28% of the variance.

LIMITATIONS, REASONS FOR CAUTION

Given the nature of the study focusing on sexual functioning, a potential selection bias cannot be excluded. It is possible that those women with the most severe sexual and/or psychological disturbances did or did not choose to participate in our study.

WIDER IMPLICATIONS OF THE FINDINGS

The study results add new data to the very limited knowledge about psychosexual functioning of women with MRKH syndrome and are of importance for more adequate counseling and treatment of these women.

STUDY FUNDING/COMPETING INTEREST(S)

The research was financially supported by the Dutch Scientific Society of Sexology (Nederlandse wetenschappelijke Vereniging Voor Seksuologie). The funding was unrestricted, and there was no involvement in the conduct of the research. There are no conflicts of interest to declare.

A randomized, placebo-controlled laboratory study of the effects of D-cycloserine on sexual memory consolidation in women

RATIONALE AND OBJECTIVE

The aim of this study was to investigate the possible facilitating effect of the partial NMDA receptor agonist D-cycloserine (DCS) on memory consolidation of conditioned sexual responses and to examine the capability of DCS to reduce context-specificity of learning.

METHODS

In a randomized placebo-controlled double-blind trial, 50 healthy females were exposed to a differential conditioning procedure. Two pictures of a male abdomen were used as conditional stimuli (CSs), of which one (the CS+) was followed by the unconditional stimulus (US), a genital vibrotactile stimulus. After the conditioning session on day 1, participants received either 125 mg of DCS or a placebo. The effects of DCS on affect, sexual arousal and US expectancy in response to the CS+ and CS- were examined 24 h after the conditioning procedure.

RESULTS

A main effect of DCS was found on affect at the first test trials (p = 0.04, η_p² = 0.09), and a similar non-significant but trend level effect was found for sexual arousal (p = 0.06, η_p² = 0.07), which appeared to persist over a longer time (p = 0.07, η_p² = 0.08). Unexpectedly, ratings of positive affect and sexual arousal in response to both the CS+ and the CS- were higher in the DCS condition compared to the control condition, possibly indicating that DCS administration reduced stimulus specificity. Since the results did not show clear evidence for context learning, we were not able to test effects on context-specificity of learning.

CONCLUSION

Although largely inconclusive, the results provide tentative support for a facilitating effect of DCS on affect and sexual arousal in response to stimuli that were presented in a sexual conditioning procedure, however, no conclusions can be drawn about effects of DCS on sexual reward learning, since the design and results do not lend themselves to unambiguous interpretation.
