    Ejaculation frequency and prostate cancer

    Contrary to some case study research, a new epidemiological study showed no correlation with ejaculation frequency and increased risk of prostate cancer, in fact quite the opposite is suggested. So for all you orgasmic wunderhands, now you have some justifications.

    CONTEXT: Sexual activity has been hypothesized to play a role in the development of prostate cancer, but epidemiological data are virtually limited to case-control studies, which may be prone to bias because recall among individuals with prostate cancer could be distorted as a consequence of prostate malignancy or ongoing therapy. OBJECTIVE: To examine the association between ejaculation frequency, which includes sexual intercourse, nocturnal emission, and masturbation and risk of prostate cancer. DESIGN, SETTING, AND PARTICIPANTS: Prospective study using follow-up data from the Health Professionals Follow-up Study (February 1, 1992, through January 31, 2000) of 29 342 US men aged 46 to 81 years, who provided information on history of ejaculation frequency on a self-administered questionnaire in 1992 and responded to follow-up questionnaires every 2 years to 2000. Ejaculation frequency was assessed by asking participants to report the average number of ejaculations they had per month during the ages of 20 to 29 years, 40 to 49 years, and during the past year (1991). MAIN OUTCOME MEASURE: Incidence of total prostate cancer. RESULTS: During 222 426 person-years of follow-up, there were 1449 new cases of total prostate cancer, 953 organ-confined cases, and 147 advanced cases of prostate cancer. Most categories of ejaculation frequency were unrelated to risk of prostate cancer. However, high ejaculation frequency was related to decreased risk of total prostate cancer. The multivariate relative risks for men reporting 21 or more ejaculations per month compared with men reporting 4 to 7 ejaculations per month at ages 20 to 29 years were 0.89 (95% confidence interval [CI], 0.73-1.10); ages 40 to 49 years, 0.68 (95% CI, 0.53-0.86); previous year, 0.49 (95% CI, 0.27-0.88); and averaged across a lifetime, 0.67 (95% CI, 0.51-0.89). Similar associations were observed for organ-confined prostate cancer. Ejaculation frequency was not statistically significantly associated with risk of advanced prostate cancer. CONCLUSIONS: Our results suggest that ejaculation frequency is not related to increased risk of prostate cancer.
