How often should men have sex or ejaculate to help prevent prostate cancer?

ANSWER

In one study, the exact number of times didn’t matter. Basically, the more men ejaculated in a month, the less likely they were to get prostate cancer.

Why might ejaculation help prostate health? Experts aren’t sure. Some believe that it can flush out harmful chemicals that might build up in semen. Still, there’s no proof that ejaculating more actually causes lower chances of prostate cancer. For now, doctors just know they’re connected. It may be that men who do it more tend to have other healthy habits that are lowering their odds.
