Tricare and infertility

Anyone have troubles with conceiving and used tricare to help you out? We are stationed at a base that has no medical facility so we have to use civilian doctors. I'm not sure how tricare works with infertility. He is getting checked in a couple weeks. I know they pay for any medical problems, but not for ivf and things in that nature right? Idk what else tricare will cover. Do they pay for sperm count and like endometriosis or other infertility problems? Or pay for the pills to help you out?
