Statistically, prostate cancer is an old man's killer. They're really saying, ride your bike, live to a ripe old age.
The Telegraph has a slightly more balanced version of the study findings.
The main point of the study was to look at issues around infertility and erectile dysfunction, and suggests that we can still get it up and produce brats, so hurrah for that.
The prostate stuff was a side-finding, and this quote suggests that they would need to be confirmed by a study more focused on these issues:
“We were quite surprised by the size of the finding for prostate cancer so it does warrant further investigation, but we can’t draw any conclusions from the study."
