Hello.
There is no conclusive evidence on the association of a risk to the enlarged prostrate with ejaculation. And the main contractile tissue is separate from the Prostate, thus eliminating any possible harm to urethra the gland during ejaculation. In fact, the prostate gland helps prevent retrograde ejaculation as it presses the urethra prior to the main contractile tissue.Removal of the hypertrophied part can cause retrograde ejaculation. You might need to consult your GP or a Surgeon for more information regarding this issue.
Best Regards
