The protective effect of frequent intercourse is strongest for low-risk prostate cancer.
An ejaculation frequency of 21 or more times per month at age 20–29 years and 40–49 years is associated with a significant 19% and 22% decreased risk of a PCa diagnosis, respectively, compared with a frequency of 4–7 times per month in adjusted analyses, Jennifer R. Rider, MD, of the Boston University School of Public Health, and colleagues reported. In addition, results showed that ejaculation frequency at age 20–29 years was significantly associated with intermediate-risk PCa. Men in this age group who had 13 or more ejaculations per month experienced a significant 27% reduction in the risk of a diagnosis of intermediate-risk PCa compared with those who had 4–7 ejaculations per month. Ejaculation frequency was not significantly associated with a diagnosis of high-risk PCa or regional/distant metastases, according to the investigators.
Men often ask me about the effects of sexual activity on prostate cancer. This study shows that more frequent relations help prevent prostate cancer. The amount of activity needed to have this benefit seems high to me. Being active more than 2 of 3 days is much more than most men are currently experiencing.
I will need to add this to the list of things I tell men about how to stay healthy.
