I'm a new member and I just happened to stumble upon your question. This issue came up for me a couple of months ago. I spoke to both pharmacists and my OB doctor to find out that answer. The pharm says it don't. the doctor says it very well could, not positive, but be safe than be sorry. the last thing you want to do is have your wife get pregnant. winstrol can be very, very dangerous for the baby.
