As scientists reveal that regular intercourse may significantly reduce the risk of developing prostate cancer, here are five other health benefits associated with an active sex life
Researchers at the University of Montreal have published the results of a study which suggests that men who had slept with more than 20 women lowered their risk of developing prostate cancer by almost a third, and were 19 per cent less likely to develop the most aggressive form of the disease.
The study looked at more than 3,200 men over a four year period and found that men who had more sexual intercourse were less likely to develop prostate cancer.
Men who had more sexual partners were more likely to have more sex than those in monogamous relationships.
This is only the latest in a long line of academic studies which claim to have found a link between an active sex life and better general health.
Here are 5 other surprising health benefits of having more sex.
1. It could make you look younger
In 2013, Dr David Weeks, former head of old age psychology at the Royal Edinburgh Hospital, told a British Psychological Society conference that his research showed that men and women who have an active sex life look between five and seven years younger than their actual age.
“Sexual satisfaction is a major contributor to quality of life, ranking at least as high as spiritual or religious commitment,” Dr Weeks said.
2. It could prevent you having a heart attack
In 2010 scientists at the New England Research Institute in Massachusetts published the results of a 16-year study, the Massachusetts Male Ageing Study, which analysed over 1000 men. The study found that men who had sex at least twice a week were up to 45 per cent less likely to develop life-threatening heart conditions than men who have sex less than once a month. Researchers said the benefits of sex could be due to both the physical and emotional effects on the body.
3. It could boost your immune system
Researchers at Wilkes University in Wilkes-Barre, Pennsylvania, found that people who have sex once or twice a week receive a boost to their immune system which could help ward off colds and flu. In the 1999 study, scientists measured levels of immunoglobulin A (IgA), an antigen found in saliva, and found a 30pc increase in IgA levels in those who had regular sex. However, Clifford Lowell, an immunologist at the University of California, warned that: “Sexually active people may be exposed to many more infectious agents than sexually non-active people.”
4. It could improve your brain function
In March 2013 scientists at the University of Pavia, Italy published the results of research which suggested that people who have regular sex, especially those in new relationships, displayed an increase in cranial nerve growth, crucial to mental alertness. The findings were supported by a separate study of male rats by scientists at Princeton University. Researchers divided the rats into two groups – one of which had its sexual activity severely limited – and found that the rats which mated more often displayed increased nerve growth.
5. It could make you less stressed at work
In 2006 researchers at the University of Paisley, Scotland, found that individuals who had more sex were better at dealing with stress. The study examined 22 men and 24 women over a two week period and found that those who had regular sex exhibited less of an increase in blood pressure when placed in stressful situations such as public speaking.

Sleeping with more than 20 women reduces risk of prostate cancer by nearly one third
The University of Montreal has found that men who had sex with more than 20 women lower their prostate cancer risk
Sleeping with more than 20 women protects men against prostate cancer, a study has suggested.
Men who had slept with more than 20 women lowered their risk of developing cancer by almost one third, and were 19 per cent less likely to develop the most aggressive form.
In contrast, men who slept with 20 men doubled their risk of developing prostate cancer compared with men who have never had sex with another man.
Researchers at the University of Montreal believe that intercourse protects men, and men who are more promiscuous have more sex than those in monogamous relationships.
However, for homosexual men the benefit is lost because of the increased risk of picking up a sexually transmitted disease, and the damage to their bodies from intercourse. However gay men with just one partner are at no greater risk.
“It is possible that having many female sexual partners results in a higher frequency of ejaculations, whose protective effect against prostate cancer has been previously observed in cohort studies,” said lead researcher Dr Marie-Elise Parent.
But when asked whether public health authorities should recommend men to sleep with many women in their lives Dr Parent added: “We’re not there yet.”
The study looked at more than 3,200 men over a four year period between 2005 and 2009.
Overall, men with prostate cancer were twice as likely to have a relative with cancer. However, the researchers were surprised to find that the number of sexual partners also affected the development of their cancer.
Men who said they had never had sexual intercourse were almost twice as likely to be diagnosed with prostate cancer as those who said they had.
When a man has slept with more than 20 women during his lifetime there was a 28 per cent reduction in the risk of having prostate cancer, and a 19 per cent reduction for aggressive types of cancer.
On the other hand, those who have slept with more than 20 men are twice as likely to be diagnosed with prostate cancer of all types compared to those who have never slept with a man.
And their risk of having a less aggressive prostate cancer increases by 500 per cent compared to those who have had only one male partner.
Dr Parent said that she could only formulate “highly speculative” hypotheses to explain the association.
“It could come from greater exposure to STIs, or it could be that anal intercourse produces physical trauma to the prostate,” she said.
Previous studies have found that sexual intercourse may have a protective effect against prostate cancer because it reduces the concentration of carcinogenic crystal-like substances in the fluid of the prostate.
The study, published in the Journal Cancer Epidemiology is the first to find a link between the number of sexual partners and the risk of developing cancer.
“We were fortunate to have participants from Montreal who were comfortable talking about their sexuality, no matter what sexual experiences they have had, and this openness would probably not have been the same 20 or 30 years ago,” said lead researcher Dr Marie-Elise Parent.
“Indeed, thanks to them, we now know that the number and type of partners must be taken into account to better understand the causes of prostate cancer.”
