No Sperm, Raising T

I am crying as I write this...DH had testicular cancer and had one removed before we met. Testosterone was in the 190s for quite a while. Last year we started TTC his doc found a varicocele and he had it removed in Feb. Started on Clomid and fertilaid went for testorone draw it's up in the 250s but no sperm in S.A..The doctor is talking about trying to pull it from his testicle next if there is no sperm after 6 more months. He is agreeing to donor sperm if nothing else works but i think hes doing it just to make me happy. He thinks that if this doesn't work that I am going to leave him. I would not be able to deal if a donor isn't truly what he wants.
