Frequent Ejaculation May Protect Men from Low-risk Prostate Cancer
Men who ejaculate at least 21 times a month have a lower risk of prostate cancer compared to men who only ejaculate four to seven times a month, according to a study that followed a large group of men for nearly two decades. The link, however, was strongest for low-risk disease, and the study — published in the journal European Urology — did not find any impact from ejaculation frequency on a diagnosis of high-risk prostate cancer. The 31,925 study participants were part of the Health Professionals Follow-up Study, where they reported how often they ejaculated in a 1992 questionnaire. The report, “Ejaculation Frequency and Risk of Prostate Cancer: Updated Results with an Additional Decade of Follow-up,” was based on follow-up through 2010, where researchers noted prostate cancer diagnoses and outcomes. Researchers at the Harvard T.H. Chan School of Public Health, where the study was performed, assessed the impact of ejaculation in men ages 20-29, or 40-49, at the time of the questionnaire. They also looked at how ejaculation frequency in the year before the questionnaire related to cancer diagnoses. The questionnaire did not ask men to specify whether ejaculation was achieved by sexual intercourse or masturbation. The research team had hypothesized that more frequent ejaculations might protect men from prostate cancer, and this was indeed what they found. The risk was about 20 percent lower for men who ejaculated 21 times or more during an average month, compared to those wh
