dodgeball,
Sorry to hear about your condition bro - didn't know anti depressants could cause testicular atrophy.
Well, here's a *possible* solution - take some Clomid (generic name Clomiphene Citrate) (50mg) and Nolvadex (generic name Tamoxifen Citrate) (20mg) every day for a month. Clomid & Nolva are used successfully to stimulate LH & FSH production which in turn increases testosterone & sperm production, in hypogonadal males.
Then go and get your serum testosterone levels checked via blood test in 2 weeks upon discontinuation. Also, feel and see if your 'boys' are back to their normal size after 1 month.
Your doc might prescibe the same therapy and if he doesn't, do ask him what he thinks about the above therapy.
Notice I said *possible* - some ppl need to be on a dose > than a month to see significant results and/or use additional drugs like HCG. Of course , the last of line treatment would be on testosterone(TRT) for the rest of your life but I don't think you'll have to resort to this as your condition was artifically induced (anti deps).
Good luck and keep us informed of your progress.
