I have gone through open heart surgery almost 20 years back and I have been under medication such as Warfarin, lanoxin, calaptin, cordarone etc. since then. Now I got married for 2 yrs and my wife could not get pregnant. I just want to know could my surgery and after medication effect my ability to make my wife pregnant. I had met a doctor and suggest me to take sperm test. I am wondering if there is any treatment for any deficiency if the test comes positive. I would be very grateful if anyone suggest a bright ideas regarding my problem.
