The title says it all.

However, I do not agree with their conclusion that ejaculating often will prevent prostate cancer.

Ejaculation has nothing to do with carcinogenesis.

Men Who Have Had Sex With More Than 20 Women May Have Lower Risk Of Prostate Cancer.

The New York Daily News (10/29, Engel) reports that research published in Cancer Epidemiology suggests that “men who have had sex with more than 20 women have a 28% lower chance of being diagnosed with prostate cancer.” However, “having more than 20 male partners doubles one’s prostate cancer risk...as does never having sex.”

The New York Post (10/29) reports that according to the study’s lead researcher Marie-Elise Parent, “It is possible that having many sexual partners results in a higher frequency of ejaculations, whose protective effect against prostate cancer has been previously observed in [other] cohort studies.”

HealthDay (10/29, Foster) reports that researchers also found that men “who had more than 20 female partners were...19 percent less likely to get a more aggressive type of prostate cancer.”

The Telegraph (UK) (10/29, Knapton) reports that “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.” But, “gay men with just one partner are at no greater risk.”
