A study from Harvard and Boston universities found that men who ejaculate 21 times a month were a third less likely to develop prostate cancer.
Published in the journal European Urology, researchers pulled the data from 31,925 men who gave their average monthly number of ejaculations. The data comes from 1992 until 2010.
“We evaluated whether ejaculation frequency throughout adulthood is related to prostate cancer risk in a large US-based study,” the study authors wrote. “We found that men reporting higher compared to lower ejaculatory frequency in adulthood were less likely to be subsequently diagnosed with prostate cancer.
“These findings provide additional evidence of a beneficial role of more frequent ejaculation throughout adult life in the etiology of PC [prostate cancer], particularly for low-risk disease.”
Ejaculating has been proven to help in other ways as well. When done more often, ejaculation can lead to decreased stress, according to Men’s Health. It can also help with sleep.
After skin cancer, prostate cancer is the most common cancer among American men. In 2021, the American Cancer Society estimates there will be 248,530 new cases of prostate cancer. About 34,130 men will die from the disease.
Health experts also estimate that 1 in 8 men will have prostate cancer, and about 1 in 41 will die of it. Most men who are diagnosed with prostate cancer are 65 or older.
While prostate cancer is serious, most of those diagnosed with it don’t die, according to the American Cancer Society. Over 3.1 million people in the U.S. are living today who have had prostate cancer.
