While the results have been consistent, researchers aren’t completely sure why ejaculating seems to reduce the risk of prostate cancer.
Ejaculation does seem to be a measure of overall health status in that men who are at the very low end of ejaculation (zero to three times per month) were more likely to have other medical problems and die prematurely from causes other than prostate cancer.
Further research is needed to identify the biological mechanism responsible for reducing the risk.
