I'm curious why you're asking. Was your husband's sperm count abnormal due to alcohol? I'm only curious 'cause my husband & I were drinking wine every night (except from ovulation - AF) and we just met with a fertility doctor on Friday for the first time. The most important thing he told us is that neither of us can drink anymore alcohol & that whatever your husband does right now will affect his sperm for two months! I was pretty surprised. He did tell me that the alcohol we did drink won't affect my baby if I happen to get pregnant this cycle, but that it could be the reason why we're not getting pregnant in the first place. Anyway, just thought I'd throw that out there :)
it can not be "reversed". only fix - going forwrad is to limit alcohol consumption and time.
