这个研究的结果：
During 480 831 person-years, 3839 men were diagnosed with PCa. Ejaculation frequency at age 40–49 yr was positively associated with age-standardized body mass index, physical activity, divorce, history of sexually transmitted infections, and consumption of total calories and alcohol. Prostate-specific antigen (PSA) test utilization by 2008, number of PSA tests, and frequency of prostate biopsy were similar across frequency categories. In multivariable analyses, the hazard ratio for PCa incidence for ≥21 compared to 4–7 ejaculations per month was 0.81 (95% confidence interval [CI] 0.72–0.92; p < 0.0001 for trend) for frequency at age 20–29 yr and 0.78 (95% CI 0.69–0.89; p < 0.0001 for trend) for frequency at age 40–49 yr. Associations were driven by low-risk disease, were similar when restricted to a PSA-screened cohort, and were unlikely to be explained by competing causes of death.

Conclusions
These findings provide additional evidence of a beneficial role of more frequent ejaculation throughout adult life in the etiology of PCa, particularly for low-risk disease.


PCa was less frequently diagnosed among men in the higher ejaculation frequency categories:



EPM = ejaculations per month
PCa = prostate cancer

但也不要被21次误导，文中也提到40岁以上人群超过13次的也只有32%：

Ejaculation frequency declined with age. The proportion of men reporting average frequency of ≥13 EPM was 57% at age 20–29 yr but dropped to 32% at age 40–49 yr.

大爷们不要自卑

看到别人21次，大爷们表示心里慌得很，一定要把这个研究弄弄清楚

结论一看就是缺心眼儿。二十来岁的小伙子得前列腺癌症的本来就少，什么癌症都少。按这种逻辑，5、6岁的小男孩，一个都没得这病的，那是不是就能得到一次都不做的，就不得？
