Given that adiposity is related to poorer female sexual function, among many other health problems, the present study aimed at testing the hypothesis that larger waist circumference, an index of subcutaneous and abdominal fat mass, is associated with lack of specifically vaginal orgasm. Study design One hundred and twenty Portuguese women of reproductive age had their waist measured and reported their past month frequency of penile-vaginal intercourse (PVI), vaginal orgasm, orgasm from clitoral masturbation during PVI, non-coital partnered sex (in the absence of same-day PVI), non-coital partnered sex orgasm (regardless of same-day PVI), masturbation, and masturbation orgasm.
In both simple and partial correlations (controlling for age, social desirability responding, relationship status, and cohabitation status), larger waist circumference was associated with lack of any vaginal orgasm and with having masturbated in the past month. In a multiple regression, larger waist circumference was independently predicted by lesser frequency of vaginal orgasm, greater frequency of masturbation, and older age.
Abdominal fat mass appears to be adversely associated with lesser capacity for vaginal orgasm, but not for orgasms from other sexual activities. Results are discussed in the context of vaginal orgasm being relatively more contingent on situations of increased fitness in both partners.
鉴于肥胖与较差的女性性功能以及许多其他健康问题相关,本研究旨在检验以下假设:腰围较大(皮下和腹部脂肪量的一个指标)与缺乏特异性阴道高潮有关。研究设计:对120名葡萄牙育龄妇女测量了腰围,并报告了她们过去一个月阴茎-阴道性交(PVI)的频率、阴道高潮、PVI期间阴蒂自慰高潮、非性交伴侣性行为(在没有当日PVI的情况下)、非性交伴侣性行为高潮(无论当日是否有PVI)、自慰以及自慰高潮的情况。
在简单相关性和偏相关性分析中(控制年龄、社会期望反应、恋爱状况和同居状况),腰围较大与缺乏任何阴道高潮以及过去一个月有自慰行为相关。在多元回归分析中,阴道高潮频率较低、自慰频率较高和年龄较大可独立预测腰围较大。
腹部脂肪量似乎与阴道高潮能力较低存在负相关,但与其他性活动的高潮无关。在阴道高潮相对更取决于双方健康状况改善情况的背景下对结果进行了讨论。
