Study suggests a connection of body's choice of menopause

Study suggests a connection of body's choice of menopause

Study author Megan Arnot, a Ph.D. candidate at the University of College London Department of Anthropology, told Newsweek the team wasn't expecting the link between sex and age of menopause to stretch further than penetrative sex, "suggesting that it is the mechanism of sex that might influence menopause timing".

"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", she added.

The researchers also wanted to look into a theory that exposure to male pheromones (for example, from living with men) delays menopause. And secondly because the issue of menopause and sex is such a complex one.

Over the next decade, 45% of women had natural menopause, at age 52 on average.

"We didn't replicate the findings from old research exhibiting that simply being married is connected to a later ANM (age of natural menopause), seemingly owing to the variable cultural and temporal settings of old research", the authors wrote.

The research is based on data collected from 2,936 women, recruited as the baseline cohort for the SWAN study in 1996/1997.

The most frequent pattern of any sexual activity was weekly, with 64 per cent saying they had engaged in some form.

Menopause timing could be adaptive in response to sexual behavior, the investigators concluded. We teach our students how to think, not what to think, and see them as partners, collaborators and contributors. This included how often they engaged in sexual activity, including sexual touching or caressing, oral sex, sexual intercourse and masturbation.

However, 46% were starting to experience menopause transition when the study began, with symptoms such as changes in their period cycle and hot flashes.

"There may be a biological energetic trade-off between investing energy into ovulation and investing elsewhere - such as keeping active by looking after grandchildren", Arnot said. A majority of the women (78%) were married or in a relationship and 68% of the women lived with their partner.

Osteoporosis is also more likely in menopausal women, which involves having weak and brittle bones.

The reason may be because "ovulation requires a lot of energy, and it has also been shown to impair your immune function".

Rather than weekly sex delaying the menopause, it could be that women who are in the early stages of the menopause start to have less sex.

That's because many factors affect whether someone is having sex, and when the menopause happens. Those who had sex weekly were 28 per cent less likely to have entered menopause, and even those who had sex once a month reduced their chance by 19 per cent.

"The significance and importance of these findings are mainly of scientific interest - the importance of these findings from the health perspective is questionable", he said.

Arnot stressed: "We don't completely understand the mechanism or direction of causation-so we don't want to suggest that any behaviors will completely slow down the arrival of the menopause".
