Globally, on average, women experience the menopause at around the age of In recent years, scientists have begun to uncover factors that influence this variation, with increased smoking and an early first period being linked to an earlier age of natural menopause.
We found that women who had sex at least weekly or monthly were less likely to enter into the menopause throughout the duration of the year study, compared to women who had engaged in sexual activity less than monthly. The women were, on average, 45 years-old at the start of the study and were mostly married or in a relationship.
We used 11 years of existing data collected from the US. Data collection began infrom women between the ages of 42 and 52 who had not yet experienced the menopause. The women were grouped based on whether they typically engage in sexual activity weekly, monthly, or less than monthly. This measure of sexual activity included penetrative sex, oral sex, sexual touching and masturbation. Trade-offs are important within biology, as the amount of energy the body has to have to expend on physiological processes is finite.
In other words, energy used for one Ladies looking sex Arnot cannot be used for another, and once it has been used it is gone. In terms of the menopause, it may be that there comes a point in life where energy invested into ovulation may be better off used elsewhere. Ovulation is costly to the body. Not only does it take a lot of energy to maintain eggs and release them every month.
The whole point of ovulation is that the body is making itself ready for pregnancy, but if a woman is not having any sex, then there is no chance of conception. This is why we included different types of sexual activity in the analysis, as all are forms of vaginal stimulation, that could send cues to the body of a possible pregnancy.
In evolutionary terms, this means that age of menopause may be somewhat adaptive in response to the likelihood of becoming pregnant. Once ovulation has stopped, energy can be expended elsewhere — such as into grand-parenting activities.
This ties in with existing research that suggests the menopause originally evolved in our evolutionary history to allow women to engage in grand-mothering activities. : How you experience the menopause may have a lot to do with your family.
There are of course many contributing factors to the age of menopause — levels of sexual activity just being one of them. Though of course there is no behavioural or medical intervention that can delay the menopause completely — it is a biological inevitability at some point for all women. Be Curious — Leeds, Leeds.
