my advice to you would be to get him on fertilaid for men. I had my DH on that for a few months and now he is also on Tribulus Terrestris.
and we have not had another SA done yet but DH swears its working.
oh also hun it takes about 3 months for the supplements to make a difference in count, quality and mobility.
im sorry I know how hard it is TTC and having it not happen for you. we have TTC for 2 years now.
