Frequent ejaculation lowers prostate cancer risk
21 April 2016
A side benefit of frequent ejaculation may be a lower risk of prostate cancer, a study of more than 31,000 men shows.
The men were asked to report the average number of times they ejaculated per month during 3 periods: age 20 to 29 years, age 40 to 49 years, and the year before the questionnaire distribution.
The relative risk for prostate cancer was about 20% lower in men who ejaculated at least 21 times a month, compared with those who ejaculated 4 to 7 times a month.
The US authors say their research provides the strongest evidence to date of the role of ejaculation in cancer prevention.The reduction in prostate cancer risk for high-frequency ejaculators was seen across all 3 time periods.
However, there was no association between ejaculation frequency and high-grade, advanced, or lethal disease.
“In a large prospective study with long-term follow-up, men who reported more frequent ejaculation in adulthood had a lower risk of total incidence of prostate cancer”, the Boston-based researchers write in the journal European Urology.
“Ejaculation frequency represents a potentially modifiable risk factor for prostate cancer.”
During the 18-year follow-up, 3839 men were diagnosed with prostate cancer, and 384 of those cases were lethal.

Prostate cancer treatment
There are different options for managing and treating prostate cancer, your treating specialist will let you know your options based on the stage and grade of the prostate cancer, as well as your general health, age and preferences.
Health checks you should have: a checklist
Everyone should have regular examinations and screening tests to help detect diseases early, before symptoms have developed. Talk to your GP about health checks you should have.
Prostate cancer screening - what's best?
Deciding whether or not you should get a PSA test for prostate cancer is a complex decision – a new study shows its limitations.
Health checks men should have
Check out the screening tests, examinations and self-checks that all men should do to stay as healthy as possible and detect conditions as early as possible to improve outcomes.
Prostate specific antigen (PSA) tests
A PSA test measures the amount of prostate specific antigen in the blood. PSA tests can be used as a screening test for prostate cancer. Find out about the risks and benefits of PSA screening.
