More Women, More Sex, Less Prostate Cancer
Back in the 70s, when free love was everywhere, no one thought much about having multiple partners. Then in the 80s, with the ugly appearance of AIDS, that pretty much went away. In the years since, the 70s never really came back. People were more responsible and chose partners appropriately.
But now a shocking new study has found that the more female sexual partners a man has had, the lower his risk of prostate cancer.
Unfortunately, the same does not hold true for men with many male sexual partners.
According to newswise.com, compared to men who have had only one partner during their lifetime, having sex with more than 20 women is associated with a 28% lower risk of one day being diagnosed with prostate cancer, according to researchers at the University of Montreal and INRS - Institut Armand-Frappier. However, having more than 20 male partners in one's lifetime is associated with a twofold higher risk of getting prostate cancer, compared to those who have never slept with a man.
The study covered 3,208 men who responded to a questionnaire on, among other things, their sex lives. Of these men, 1,590 were diagnosed with prostate cancer between September 2005 and August 2009, while 1,618 men were part of the control group.
Overall, men with prostate cancer were twice as likely as others to have a relative with cancer. However, evidence suggests that the number of sexual partners affects the development of the cancer.
Even more astounding, 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 is a 28% reduction in the risk of having prostate cancer (all types), and a 19% reduction for aggressive types of cancer. "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," study author Marie-Elise Parent, a professors at the university’s School of Public HealthParent explained.
And did it matter the age at which men first had sexual intercourse or the number of sexually transmitted infections they had contracted? Nope.
The data indicate that having only one male partner does not affect the risk of prostate cancer compared to those who have never had sexual intercourse with a man.
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%, compared to those who have had only one male partner.
