In mammals, the effects of ovarian steroids influence sexual behavior. In humans, there are a few studies that take into account if ovulation occurs.
The study aims to investigate if a woman's sexuality changes during the week and over the menstrual cycle, and if so, in what way.
This is a prospective cohort study; 1,957 heterosexual women were involved over the period January 2004-December 2011. Two subgroups were taken into consideration, women having a partner and singles.
Sexual interview and the Female Sexual Function Index and Female Sexual Distress Scale questionnaires were used to exclude women with sexual dysfunction. Women with ovulation confirmed by sonography were enrolled. Women were given diary cards on which to report their daily sexual activity. Serum concentrations of estradiol, progesterone, total testosterone, sex hormone binding globulin, and free androgen index were measured during the follicular, periovular, and luteal phase of the menstrual cycle.
One thousand one hundred eighty women (age range 18-40 years) were included in the analyses. Of them, 925 had a heterosexual relationship and 255 were single. Women with a partner had more sexual activity during the weekend, while the singles had a constant sexual activity over the week. The sexual activity of singles was higher during the ovulatory phase and lower during menses than that of the women with a partner. A linear correlation between sexual activity and androgenic hormonal profile during the menstrual cycle in women with and without a partner was observed.
Ovarian steroids modulate a woman's sexual activity. This aspect was more evident in singles than in women having a partner, in which a variety of nonhormonal factors can have a role.
在哺乳动物中，卵巢类固醇的作用会影响性行为。在人类中，有一些研究考虑了排卵是否发生。
本研究旨在调查女性的性行为是否会在一周内和月经周期中发生变化，如果会，变化的方式是什么。
这是一项前瞻性队列研究；共有 1957 名异性恋女性参与了 2004 年 1 月至 2011 年 12 月期间的研究。考虑了两个亚组，有伴侣的女性和单身女性。
使用性访谈和女性性功能指数和女性性困扰量表问卷排除有性功能障碍的女性。招募排卵经超声确认的女性。女性被给予日记卡，记录她们的日常性行为。在卵泡期、排卵前期和黄体期测量血清雌二醇、孕酮、总睾酮、性激素结合球蛋白和游离雄激素指数浓度。
1180 名（年龄范围 18-40 岁）女性被纳入分析。其中 925 名有异性恋关系，255 名单身。有伴侣的女性在周末性行为较多，而单身女性每周性行为较为稳定。单身女性的排卵期性行为较高，月经期较低，而有伴侣的女性则相反。在有伴侣和无伴侣的女性中，性活动与月经周期中雄激素激素谱之间存在线性相关。
卵巢类固醇调节女性的性活动。在单身女性中，这一方面比有伴侣的女性更为明显，其中各种非激素因素可能起作用。
