What has been reported to me in addition to what I read are the following impacts on men’s semen: 1- change in consistency, 2- decreased volume, and 3- reduced sperm count.
Men wishing to have a baby should check their sperm count. If they find that they have a problem impregnating their partner they may consider stopping the drug with a risk of losing the hair you gained from it. I have seen some scattered reports that some men have seen such a radical reduction in sperm count that they would be considered sterile; however, stopping the drug supposedly increases the sperm count over time.
