Key results and conclusions:
Men who averaged five or more ejaculations weekly in their 20s had an odds ratio (95% confidence interval) of 0.66 (0.49–0.87) compared with those who ejaculated less often.If this is true, then the odds are definitely in my favor. In my 20's, I'm pretty sure I was averaging seven times or more per week. I'm not in my 20's any more - but I think I'd better keep up the five times per week, just to be safe.
Ejaculatory frequency, especially in early adult life, is negatively associated with the risk of prostate cancer....
I love it when science recommends that I do what I'm already doing. :-)
