New data confirm an observation from several years ago that men who ejaculate more often are less likely to develop prostate cancer. The optimal frequency for sex to completion seems to be 21 times a month.

About 10 years ago, all the late night comedians were making jokes about studies that found that the more often men ejaculate semen, the less likely they are to suffer prostate cancer. A new study presented at the May conference of the American Urological Association provides further data that confirm that safe sex seems to prevent, or at least to forestall, the need for treatment of prostate cancer.

It is a lot better to prevent prostate cancer than to treat it, since treatment of this disease almost always involves surgical removal of the gland.

A New Study Of Prostate Cancer Risk

The new data come from the Health Professionals Follow-Up Study, which has been following 32 thousand men, most of them physicians and other health professionals, for 18 years. The men in the study have opened their medical records to ongoing examination, and provide detailed information about their lifestyle choices.

When the participants in the study were recruited in 1992, they were asked:

  • How many times a week they ejaculated at ages 20 to 29, and
  • How many times a week they ejaculated at ages 40 to 49, and
  • How many times a week they ejaculated in previous year,

from which the researchers computed a lifetime average of weekly ejaculations. By the time men reach their forties, most ejaculate (through either sexual intercourse or masturbation) 8 to 12 times a month. Only 8.8 percent ejaculate as often as 21 times a month.

The average age of men in the study currently is 59 years. At this point, of the nearly 32 thousand men in the study, 3384 have already developed prostate cancer, and 384 cases have been fatal.
 
Frequent seminal emission is not a guarantee against prostate cancer, but men who release semen at least 21 times a month are at least 20 percent less likely to develop the disease at any time during their lives. As men get older, sexual activity makes a bigger and bigger difference.

Just How Important Is Sex To Prostate Health?

An earlier study of the same group of men found even starker differences in cancer rates among men according to age. In 2004, researchers studying the same group of men found that:

  • Men who ejaculated at least 21 times a month during their twenties were 11 percent less likely to develop prostate cancer than men who only ejaculated four to seven times a month.
  • Men who ejaculated at least 21 times a month during their forties were 32 percent less likely to develop prostate cancer than men who only ejaculated four to seven times a month.
  • Men who ejaculated at least 21 times a month during their fifties and sixties were 49 percent less likely to develop prostate cancer than men who only ejaculated four to seven times a month.

The older a man gets, the bigger a beneficial difference frequent sexual activity, to climax, seems to make in prostate health. A study in Japan also found that:

  • Men who had more sexual partners before marriage were less likely to develop prostate cancer than men who had fewer sexual partners.
  • Men who had more sex in their thirties and forties were up to 80 percent less likely to develop prostate cancer.
  • Men who enjoyed sex less had prostate cancer more often, and
  • Men who had more sexually transmitted diseases (presumably because they had more sex) were less likely to develop prostate cancer.
