Study: Ejaculating More Is Strongly Linked With Reduced Risk of Prostate Cancer

April 1st 2016

Men of the world, rejoice: the more frequently you ejaculate, the lower your risk might be of developing prostate cancer.

According to new data from researchers at the Harvard T.H. Chan School of Public Health, "ejaculation frequency may be inversely related to the risk of prostate cancer, a disease for which few modifiable risk factors have been identified."

"The results are compelling because there are so few known risk factors for prostate cancer that are modifiable," Jennifer Rider, one of the researchers, told ATTN:. "The results show that sexual activity is one way men can actually modify risk factors."

The survey was significant.

Researchers tracked 31,925 men who answered questions about how often they ejaculated between 1992 and 2010 to understand the relationship between frequency of ejaculation and the rate of prostate cancer.

The results were measured at three points: ages 20-29, ages 40-49, and the year before the survey was handed out. In both age ranges, men who said they ejaculated 21 times or more each month were about 20 percent less likely to receive a diagnosis than those who only hit the 4 to 7 times per month mark.

Overall, 3,839 men were diagnosed with prostate cancer over the course of the research. Prostate cancer is one of the leading causes of cancer deaths among men, according to the CDC.

"We found that men reporting higher compared to lower ejaculatory frequency in adulthood were less likely to be subsequently diagnosed with prostate cancer," the researchers wrote.

The data bolsters previous research on the health benefits of regular sexual activity.

"These findings provide additional evidence of a beneficial role of more frequent ejaculation throughout adult life in the etiology of [prostate cancer], particularly for low-risk disease," the authors wrote.
