I've been posting here for awhile now. DH and I have been struggling with mf infertility for 4+ years. Recently, DH stopped taking Arimidex (horrible side effects with really no help) and started injecting HCG subcutaneously instead of IM. Oddly, he is starting to feel much better (more energy, weight loss, elevated sex drive). Not sure which change helped. Next step is to have testosterone checked and have varicocele fixed. Fingers crossed! Anyway, I like to post updates in the case that the info might help someone here dealing with similar issues.
