[|Human|] I am a 76 year old male, status post triple bypass  1998,  more recently had an episode of atrial fib and put on coumadin. The last two times we have engaged in sexuual relations, ive had a fairly large amount of frank blood mixed with the semen. any cause for concern?  Frank in New YORK
[|AI|]  Hi Frank. Thanks for the detailed history. Bleeding is due to the Coumadin most likely. I would advise you to consult your Doctor to get your PT and INR tested and decrease the dose of your Coumadin. They decrease the clotting ability of the blood leading to such bleeding episodes. So it is safer to monitor its effect by testing the PT and INR which tells us the clotting ability of the blood. Take care and let me know if there are any clarifications which I can help with.
