I have been on Propecia for the last 3 years and it’s worked well. It has come to a stage where I would like to have a child with my wife. I have been researching for answers about effects of Propecia whilst conceiving on the internet and although there are many answers stating that it’s safe to carry on taking whilst trying to conceive, I am still unsure and not convinced. In the end I would not want to jeopardize the health of the child. May I ask, if I was to halt taking Propecia, how long should I wait to be sure that it is completely out of my system and that the sperm count and morphology would be completely back to normal?
This is a difficult question to answer. There are millions of men on this drug and I don’t believe that there is any report of the defect that is known if women took the drug. Also the semen levels are very, very low and the drug really impacts the growing fetus in the first trimester. Most of the warnings are medical-legal ones. The drug fixes to tissues in the body and this tissue fixation lasts about 1 week. If there are sperm reductions, it could take up to 6 months for this to reverse, probably less.
