Antidepressants

So we have been ttc for over a year. I have had a fertility work up and everything was fine and I'm pretty fertile, so I decided to send my husband to the doctor to check his testosterone levels and everything and he comes home with a prescription for antidepressants. Yes he has depression but never needed treatment for it but I guess his doctor says different. Yes he has started taking them and I am worried it will bring his sperm count down, so I am also having him take a men's multivitamin and an extra zinc supplement. What do you all think?
