Dom Juan, Casanova, womanizers… Often pejorative qualifiers for men who multiply sexual partners. Still, this lowers their risk of prostate cancer.
The “men to women” have an advantage over others. This is not about seduction, but about their health. Compared to those who have had only one partner in their lifetime, the Dom Juan and other Casanovas are less likely to develop prostate cancer. This is the result of a study by the University of Montreal (Canada), published in the journal Cancer Epidemiology.
The Dom Juan would have fewer cancers
A 100% female team, therefore impartial, carried out this study. Quebec researchers interviewed more than 3,200 men, half of whom were diagnosed with prostate cancer between September 2005 and August 2009. Surprisingly, the risk of developing a tumor is reduced by 28% in men who have known, in the biblical sense of the term, more than 20 women in their life. The likelihood of them developing an aggressive form of prostate cancer is also reduced by 19%.
“It is possible that the fact of having had several female sexual partners results in a higher frequency of ejaculation, the protective effect of which against prostate cancer has been observed previously in cohort studies”, analyzes Marie -Elise Parent, co-author of this study. Indeed, studies have suggested that ejaculation decreases the concentration of carcinogens present in prostatic fluid.
Different results in homosexuals
If the results are cheerful, they are quite serious, and they suggest that the number of sexual partners has an impact on the development of cancer. But this is not just any partner. Indeed, men, who have had sex with more than 20 men, are twice as likely to develop a prostate tumor than those who have not attended any. This association “could relate to a greater exposure to STIs, or it could be that anal penetration produces a physical trauma to the prostate,” suggests Dr. Parent, while acknowledging that these are hypotheses. “Highly speculative”.
But here too, the importance of the number of partners matters. The likelihood of this tumor being less aggressive is 500% higher if they have experienced more than 20 than if they have only encountered one. From there to making the multiplication of partners a public health message? “We’re not there yet,” smiles Marie-Elise Parent.
