A Harvard study has revealed that men who ejaculate more often may have a lower risk of prostate cancer.
Researchers studied data from 29,342 men aged 46 to 81, collected through the Health Professionals Follow-Up Study between 1986 and 2000. Participants shared their ejaculation habits, including sexual intercourse, masturbation, and nocturnal emissions.
Men who reported 21 or more ejaculations per month had a 31 percent lower risk of prostate cancer compared to those who ejaculated four to seven times a month.
The study looked at ejaculation frequency in young adulthood (ages 20–29), middle age (ages 40–49), and the most recent year. It also considered other lifestyle factors and PSA testing, and the results remained consistent.
Prostate cancer mainly affects men over 50, and one in eight men in the UK will be diagnosed in their lifetime. Early detection often leads to successful treatment, but the disease can be symptom-free in its early stages.
Experts are not entirely sure why frequent ejaculation helps, but it is thought to help flush out harmful substances that could build up in semen.
Other studies also suggest that ejaculating more than four times a month can help reduce prostate cancer risk.
Doctors advise men to discuss any health concerns with a healthcare professional.
