STUDY QUESTION Do sexual, relational, and psychological functioning of male partners of women with Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome differ from male partners of women without MRKH syndrome? SUMMARY ANSWER Male partners of women with MRKH syndrome did not significantly differ in sexual functioning but reported higher relational satisfaction and less anxiety than the control group. WHAT IS KNOWN ALREADY To date, only a few studies have reported occasionally about sexual, psychological, and relational functioning of partners of women with MRKH syndrome. The results seem to suggest sexual satisfaction in these men, contrary to the more often reported insecurities in women with MRKH syndrome surrounding sexuality and relationships. STUDY DESIGN, SIZE, DURATION In this case–control study, 42 male partners of women with MRKH syndrome and 40 partners of women without the condition were enrolled. PARTICIPANTS/MATERIALS, SETTING, METHODS All participants were recruited through women with MRKH syndrome and age-matched women without the condition who participated in a previous case–control study on sexual, psychological, and relational functioning. Participants live in a heterosexual relationship for at least in the last 6 months and have a basic understanding of the Dutch language. They were administered a set of online questionnaires to assess sexual, relational, and psychological functioning. MAIN RESULTS AND THE ROLE OF CHANCE Partners of women with MRKH syndrome did not differ significantly in overall sexual functioning and had similar percentages of sexual dysfunction and sexual distress as the control group. Partners of women with MRKH syndrome reported significantly less relational dissatisfaction (P = 0.01; Cohen’s d = 0.6) than partners of women without the condition. There was no significant difference in overall psychological functioning or the presence of clinically relevant anxiety and depression, but the men in the MRKH group had a significantly lower anxiety score (P = 0.01; Cohen’s d = 0.6). LIMITATIONS, REASONS FOR CAUTION We were not able to reach a sample size needed for enough power to detect small to medium effect sizes. Confounding factors and selection bias cannot be excluded. WIDER IMPLICATIONS OF THE FINDINGS The study offers new knowledge on a perspective that remains underexposed so far, which makes comparison to previous literature difficult. More research is needed to apply the results in clinical practice. STUDY FUNDING/COMPETING INTEREST(S) This research was supported by the Dutch Scientific Society of Sexology (Nederlandse Wetenschappelijke Vereniging Voor Seksuologie). There was no involvement in the conduct of the research, and the funding was unrestricted. There are no conflicts of interest to declare. TRIAL REGISTRATION NUMBER N/A.

已报道的 Mayer-Rokitansky-Küster-Hauser 综合征女性男性伴侣的性、关系和心理功能——一项病例对照研究


研究问题 患有 Mayer-Rokitansky-Küster-Hauser （MRKH） 综合征的女性的男性伴侣的性、关系和心理功能与没有 MRKH 综合征的女性的男性伴侣是否不同？摘要答案 患有 MRKH 综合征的女性的男性伴侣在性功能上没有显着差异，但报告的关系满意度高于对照组，焦虑较少。已经知道的 迄今为止，只有少数研究偶尔报告了 MRKH 综合征女性伴侣的性、心理和关系功能。结果似乎表明这些男性的性满意度，这与 MRKH 综合征女性在性和人际关系方面更常见的不安全感相反。研究设计、规模、持续时间 在这项病例对照研究中，纳入了 42 名患有 MRKH 综合征的女性的男性伴侣和 40 名没有该疾病的女性的伴侣。参与者/材料、环境、方法 所有参与者都是通过患有 MRKH 综合征的女性和年龄匹配的无病症女性招募的，这些女性参与了先前关于性、心理和关系功能的病例对照研究。参与者至少在过去 6 个月内生活在异性恋关系中，并且对荷兰语有基本的了解。他们接受了一组在线问卷，以评估性、关系和心理功能。主要结果和机会的作用 MRKH 综合征女性的伴侣在整体性功能上没有显著差异，并且与对照组的性功能障碍和性困扰百分比相似。患有 MRKH 综合征的女性的伴侣报告的关系不满显着减少 （P = 0.01;Cohen 的 d = 0。6） 比没有条件的妇女的伴侣。整体心理功能或临床相关焦虑和抑郁的存在没有显著差异，但 MRKH 组男性的焦虑评分显着降低 （P = 0.01;Cohen 的 d = 0.6）。局限性，谨慎原因 我们无法达到检测中小效应量所需的样本量。不能排除混杂因素和选择偏倚。研究结果的更广泛意义 该研究提供了关于迄今为止仍未被充分曝光的观点的新知识，这使得与以前的文献进行比较变得困难。需要更多的研究才能将这些结果应用于临床实践。研究经费/利益争夺 这项研究得到了荷兰性学科学学会 （Nederlandse Wetenschappelijke Vereniging Voor Seksuologie） 的支持。没有参与研究的进行，资金不受限制。没有需要声明的利益冲突。试验注册号 N/A。
