Dear Dr. Dezube: Recently I have noticed blood in semen when I masturbate I am very concerned and would like to know how worried I should be ? During December I jumped of a high platform on a boat into the ocean and did impact my testicle, could this be the cause?

Blood in the semen can be very upsetting. Most often it's nothing more than a tiny blood vessel that burst during your ejaculation/masturbation. Occasionally, however, it could be the sign of an infection or a problem with your prostate. Hopefully, by the time you get this response, it will have cleared up. If not, I would suggest that you see a urologist (a doctor who specialized in this area). I doubt that this is related to your jump back in December, but who knows -- maybe it's related. Hope this helps. BD.
