Frequent ejaculations, especially in 20-something men, may reduce the risk of prostate cancer later in life, Australian researchers reported in the British Journal of Urology International. When they followed men diagnosed with prostate cancer and those without, they found no association of prostate cancer with the number of sexual partners as the men reached their 30s, 40s, and 50s.
But they found men who had five or more ejaculations weekly while in their 20s reduced their risk of getting prostate cancer later by a third.
Another study, reported in the Journal of the American Medical Association, found that frequent ejaculations, 21 or more a month, were linked to lower prostate cancer risk in older men, as well, compared with less frequent ejaculations of four to seven monthly.

這是一個在醫學界仍很有爭議的課題,果殼網與科學鬆鼠會曾為此問題吵得不可開交。
