Women who have less than enough s*x often enter the menopause stage earlier than they normally should.
Women who have s*x at least once a week start the menopause later than those how make love less than once a month, according to a new study.
Scientists at University College London analysed data from the US Study of Women’s Health Across the Nation (SWAN) – the “largest, most diverse and most representative longitudinal cohort study available to research aspects of the menopause transition” according to UCL.
Sexual activity was defined as sexual intercourse, oral sex, sexual touching and caressing or self-stimulation, reports Sky News.
According to the study’s first author, PhD candidate Megan Arnot: “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.
“The idea that women cease fertility in order to invest more time in their family is known as the Grandmother Hypothesis, which predicts that the menopause originally evolved in humans to reduce reproductive conflict between different generations of females, and allow women to increase their inclusive fitness through investing in their grandchildren.”
