Whether men are ‘promiscuous’ may depend on testosterone production

People have always been interested in the role of testosterone in human sexual function and sexual behavior, and many researches on related topics are based on testosterone hormone.

In a new study published in The Journal of Sex Research, W. G. Macdowall and colleagues from the London School of Hygiene and Tropical Medicine found that testosterone hormone levels are closely related to the type of intimacy and sexual behavior in both men and women.

The researchers measured testosterone hormone levels (Sal-T) in saliva samples from nearly 4,000 adults and used questionnaires to analyze the link between testosterone levels and how men and women expressed sexual desire, respectively. Analysis of the data showed that men with higher testosterone levels were more likely to have had multiple sexual partners in the past five years and were more likely to have recently had sexual intercourse with the opposite sex. And among women, those who masturbated recently, or more frequently, had significantly higher levels of testosterone. Testosterone (T) is often thought to be the biological driver of male libido, while its role in relation to female sexuality is less well known. Demographic data on the relationship between testosterone and sexual function and sexual behavior in men and women, respectively, are sparse, and past research has tended to focus only on the hormonal link between reproductive aspects such as menstruation in women. While this study further examines the sexually-related behavioral associations between men and T levels, it also helps fill a cognitive gap in the association of female sexuality with biological drivers. The study analyzed saliva samples from 3,722 participants, including 1,599 men and 2,123 women, all between the ages of 18 and 74, using a gold-standard test system based on mass spectrometry. And in the questionnaire, the participants reflected a series of questions related to sexual function and sexual behavior, including sexual interest, whether there is a sexual disorder, the frequency of masturbation, and the number/type of all partners in the past five years and so far, etc. . Overall, higher testosterone levels were more strongly associated with masturbation in women than in men, but were more strongly associated with sexual activity with a sexual partner in men. The researchers believe this may be related to women’s different meanings and motivations for masturbation and for having sex with a partner. The data showed that the mean Sal-T in men was much higher than that in women (223.5 pmol/L and 37.1 pmol/L, respectively), and gender differences in associations with Sal-T and sexual behavior were observed between the two (Table 1). 1 and Table 2).

In men, saliva-measured testosterone levels (Sal-T) are associated with masturbation, and intercourse with (both single and simultaneous) sexual partners. First, higher levels of Sal-T were associated with recency (recent masturbation) and frequency of masturbation: the average Sal- The T value is low. Higher levels of Sal-T, on the other hand, were associated with more recent sexual activity with a heterosexual partner and multiple simultaneous sexual partners in the past five years, but not with the number of sexual partners. Furthermore, the data also showed that men’s attitudes towards more “casual” sexual relationships were associated with higher levels of Sal-T: there was a significant difference between Sal-T and those with two different attitudes Associated, non-exclusive male populations who can accept or support one-night stands and marriages have higher mean Sal-T than non-supportive male populations. Testosterone levels (T) have also been linked to men having a partner and parenting in previous studies: men with partners tended to have lower T levels than single men. Men with children tended to have lower T-scores than men without children. Based on these data, it has been suggested that men with higher T-scores may be more motivated to seek sexual partners, may switch partners more frequently, and be more interested in sex with the opposite sex. But there is also some evidence that men in long-term partnerships may have similar propensities for additional sex as single men, based on similar T levels for both. In women, saliva-measured testosterone levels (Sal-T) were most strongly associated with masturbation, and the association was stronger than in men. Women who had not masturbate for more than a month had lower mean Sal-T values ​​compared to women who had recently masturbate. The frequency of female masturbation was also associated with Sal-T, with women who masturbate more than twice in the past 7 days having higher mean Sal-T compared to women who masturbate only once. Women who had sex with the same sex also had significantly higher Sal-T compared to women who had not had sex with the same sex. Past studies on the relationship between female hormones and sexual behavior tend to focus on female reproductive aspects, such as menstruation, pregnancy, and menopause, and often exclude testosterone (T) factors, so the role of T in female sexual behavior is even more unknown known. In recent years, however, testosterone (T) research has received more attention, in part because more people are seeking treatments to address women’s sexual response problems. This study is the first to examine the association between testosterone hormone (T) and aspects of sexual function and behavior using salivary measurements in both men and women. This research helps to shed more light on the role of T in female sexuality, as well as differences in the relationship between T and sexual function and behavior in men and women.
