Having less sex linked to earlier menopause

Women who engage in sexual activity weekly or monthly have a lower risk of entering menopause early relative to those who report having some form of sex less than monthly, according to a new UCL study. The researchers observed that women, who reported engaging in sexual activity weekly, were 28% less likely to have experienced menopause at any given age than women who engaged in sexual activity less than monthly. Sexual activity includes sexual intercourse, oral sex, sexual touching and caressing or self-stimulation. The research, published in Royal Society Open Science , is based on data from the USA's Study of Women's Health Across the Nation (SWAN). It's the largest, most diverse and most representative longitudinal cohort study available to research aspects of the menopause transition. First author on the study, PhD candidate Megan Arnot (UCL Anthropology), said: "The findings of our study suggest that if a woman is not having sex, and there is no chance of pregnancy, then the body 'chooses' not to invest in ovulation, as it would be pointless. There may be a biological energetic trade-off between investing energy into ovulation and investing elsewhere, such as keeping active by looking after grandchildren.
