I was depressed for sometime till I found I've low T, once I supplemented it depression disappeared. I wonder why doctors don't ask you to get your T level checked when they find you depressed instead of prescribing antidepressants.
There are plenty of people who would trade feeling better for a longer shitty life.
If you are doing TRT testicular atrophy usually isn't a concern although it could be a cosmetic concern. Taking human chorionic gonadotropin will preserve testicular function but may not return the look of your saggy nads.
