Having sex or engaging in regular sexual activity may lower the risk of early menopause, scientists say.
Researchers have observed that women taking part in sexual activity on a weekly basis were 28% less likely to have experienced menopause than those who did so less than once a month.
Sexual activity includes sexual intercourse, oral sex, sexual touching and caressing or self-stimulation.
Researchers from University College London (UCL) believe a lack of sexual activity signals the body to invest its resources elsewhere as ovulation is “a costly process”.
Megan Arnot, a PhD candidate at UCL Anthropology and first author on the study, 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.”
