a sperm count would be best to see what is goin on at bare minimum.

if he does go on cycle, make sure to do HCG on cycle, it helps keep sperm count up. 500iu 2x a week would be good. this would help negate the impact on sperm that steroids have.

and x2, yall need to talk. a fertility test now will allow him to cycle faster instead of keep waiting and such.

good luck!
