Had a good read of bikeforums and cycleforums and it appears that prostrate cancer links are tenuous, though health issues could begin or become exacerbated, especially if cycle set up is poor.

I remember a U.S. study a few years back which put afro american men as higher and asian american men as lower represented. Weight lifters and sportsmen were higher as were meat consumers vs vegetarians.

4. Q: Can the sport of bicycle riding increase the likelihood of BPH, prostate cancer or other prostate problems?
A: Prolonged cycling on a hard seat is thought to affect potency by injuring the pudendal arteries that supply blood to the penis. Cycling can also traumatize the prostate, causing an elevation in the PSA level. No evidence, to my knowledge, shows that cycling can increase the risk for benign prostate enlargement or prostate cancer.

5. Q: Is ejaculation good for prostate health?
A: The short answer is “yes.” The prostate has innumerable tiny glands located in its periphery. Their function is to drain prostatic secretions through the tiny prostatic ducts into the urethra. Approximately 90% of the fluid that comes out with ejaculation is prostatic fluid. With long periods of abstinence from ejaculation, the prostate may become filled with secretions. This condition is called congestion of the prostate.

Symptoms associated with prostatic congestion can include voiding difficulties and discomfort in the region of the prostate. In some instances, accumulation and stagnation of prostatic fluid can contribute to the development of infection in the prostate (prostatitis). Regular ejaculation has the effect of keeping the prostate “flushed out” and healthy
