In the most comprehensive study yet on the topic, men who ejaculate at least 21 times a month are far less likely to develop prostate cancer. In fact, the risk of prostate cancer in men declines over 20% if he ejaculates 21 times a month of more.
The study followed 32,000 men beginning in 1992 and continuing until 2010 – this type of longitudinal study, while expensive and time consuming, is considered the gold standard of epidemiological research. Blah, blah.. it means its a really credible study.
It has been known for some time that more frequent ejaculations can help reduce prostate cancer risk, but this is the largest and most conclusive study. And short of showing the biophysical connection between ejaculation and prostate cancer – which is really, really hard – this is pretty darn good proof that guys everywhere should be ejaculating more.
So, guys, the next time you need a little helping hand (or mouth or other cavity) from your partner… or if you ever feel shame or guilt about your masturbatory habits… keep this in mind. An orgasm a day keeps the doctor away.
