I am 61 years of age and have had blood in my semen - I had a heart catherization on December 11 and I had bruising in my groin area. I had a prostate exam on December 4 where all was normal and PSA reading was 2.26. I first noticed the blood in semen on December 21st and there are still signs of it today. Could the blood be from the bruising of the catherization. Please advise. Thank you. My email address is YYYY@YYYY .
