Don’t know what to do

Ol

Hello! We found out yesterday that my husband has inadequate sperm count and got a referral to a male specialist I was wondering what the next steps are. Will he take medicine? He dips and I know nicotine affects sperm so he’s stopping but he said he doesn’t want to take medicine but I know he’ll change his mind he always does. But any info helps. Doctor hasn’t called to make an appointment so what are some questions I can ask too
