In a highly intriguing research outcome, a Canada-based study showed that men who had sex with more than 20 women had reduced the risk of prostate cancer by 28% compared to those who are loyal to one wife or one partner, unmindful of risks it may pose to AIDS-related risks or sexually transmitted diseases and above all, the damage to millions of families around the world where men are more promiscuous.
The new finding by researchers at the University of Montreal and Institut Armand-Frappier Research Centre (INRS) in Quebec — Marie-Elise Parent and Marie-Claude Rousseau, professors at University of Montreal’s school of public health, and their colleague Andrea Spence — who had analyzed the Montreal study PROtEuS (Prostate Cancer and Environment Study), made their observations but the media, especially in India and China is going overboard taking different versions and protracting the conclusions.
The study conducted on 3,208 men showed 1,590 were diagnosed with prostate cancer between September 2005 and August 2009 while 1,618 men, who were part of the control group with more sexual partners. “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,” researchers said.
Surprisingly, men who said they had never had sexual intercourse were almost twice as likely to be diagnosed with prostate cancer than those who said they had. Finally, it concluded that when a man had 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 percent 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,” Marie-Elise Parent said.
Some studies in the past have shown that the main reason behind this was the concentration of cancer-causing substances in prostatic fluid or lowering the production of intraluminal crystalloids. The findings were published in the journal Cancer Epidemiology.
