Can masturbation prevent prostate enlargement?

Little science here: It would be difficult to find a control group. As recently as the mid-20th century, 'pop' / 'cult' claims that 'solitary vice' did terrible spiritual damage resulted in men trying very hard -- usually unsuccessfully -- to avoid the practice. Anecdotally, accelerated prostate hyperplasia seemed to result. Within reasonable limits, correlation between frequency ; BPH risk seems negligible.
