Women who have sex weekly have lower risk of entering menopause

Having sex weekly may DELAY your menopause: Scientists say not getting enough action ‘makes the body choose to stop ovulating’

  • Study compared those having sex weekly, monthly and less than monthly 
  • Sexually active women 28% less likely to experience menopause
  • Those who had sex once a month were 19% less likely to experience menopause
  • If woman is not having sex, body ‘chooses’ to stop putting energy into ovulation
  • Body may decide to invest energy elsewhere, like in caring for grandchildren 

Women who have sex every week may have a lower chance of an early menopause, according to researchers. 

University College London experts asked nearly 3,000 women – who were tracked for 10 years – about how often they had sex.

Women who engaged in sexual activity weekly were less likely to have been through the menopause at any given age than women who did so less than once a month.

For example, those who had regular sex were 28 per cent  less likely to have entered the menopause at age 51, compared to their counterparts.   

Sexual activity included full-blown intercourse, oral sex, touching and caressing, or self-stimulation.

Scientists said if a woman is not having sex and there is no chance of pregnancy, the body ‘chooses’ to stop investing energy into ovulation.

Women who have sex regularly could have a lower chance of entering the menopause early, according to researchers

Instead, their bodies may decide to invest energy elsewhere, such as in looking after grandchildren. 

The theory, known as the grandmother hypothesis, says the menopause evolved to help mothers have more children. 

It suggests that grandmothers would aid their offspring to have more of their own children by caring for the existing grandchildren. 

A woman’s immune function is hampered during ovulation, making the body more susceptible to disease. 

And so if a pregnancy is unlikely because of a lack of sexual activity, the body would divert its focus from a costly process to aiding existing relatives. 

The menopause is when a woman stops having periods and is no longer able to get pregnant naturally.   

The process is a natural part of ageing and usually occurs among women between 45 and 55. The NHS says the average age of menopause is 51.

Researchers used data collected from 2,936 women who took part in the Study of Women’s Health Across the Nation (SWAN) in the US.


Menopause is defined as the changes a woman goes through just before and after she stops her periods and is no longer able to get pregnant naturally. 

Some women go through this time with few, if any, symptoms, around 60 percent experience symptoms resulting in behavioral changes and one in four will suffer severely. 

Common symptoms include hot flushes, night sweats, vaginal dryness leading to discomfort during sex, disrupted sleep, decreased sex drive, problems with memory and concentration and mood swings.

Menopause happens when your ovaries stop producing as much of the hormone oestrogen and no longer release an egg each month.

In the UK, the average age for a woman to reach the menopause is 51, according to the NHS.

The women, an average age of 45 at the start of the study in 1996, were asked if and how often they had had sex in the past six months.

They were also asked whether they had oral sex, sexual touching, or engaged in self-stimulation in the last six months. 

The researchers found that the most frequent pattern of sexual activity was weekly (64 per cent).  

None of the women who took part had already entered the menopause, but 46 per cent were starting to experience symptoms (known as peri-menopause).

Fifty-four per cent were pre-menopausal, meaning they had not yet displayed any symptoms and were still having their periods.

Interviews were carried out both when the women first took part and then ten years later.  

Women who had sex weekly were less likely to experience the menopause, compared to those who had sex lass than monthly. 

And women who had sex monthly were less likely to experience menopause at any given age, compared to those who had sex less than monthly. 

Professor Ruth Mace, who co-authored the study, said: ‘The menopause is, of course, an inevitability for women, and there is no behavioural intervention that will prevent reproductive cessation.

‘Nonetheless, these results are an initial indication that menopause timing may be adaptive in response to the likelihood of becoming pregnant.’
