I had my first born naturally, getting off gear that I would cycle on and off, and doing a PCT.
After my first was born, I decided to jump on TRT dosage at 200mg for three years straight, along with cycles here and there on top of it. My wife and I tired for an other child a few years later, and she wasn't getting pregnant at all. I went to fertility clinic, and it turned out I had azoospermia. Doctor said to get off all gear, and I did.
I got some Chinese HCG, HMG, blasting 4000ius a week, and an entire vial of HMG 3x a week. I also took 50mg of clomid ED; even with this protocol, it took me nearly half a year to recover and get a mere 6 million sperm count, which still isn't enough to do shit.
Because my wife and I didn't want to wait more, as it is harder to get pregnant as we age, it led us to go get IVF (thankfully I didn't have to pay for it), and we have our second child now. Could I have recovered fully again and not needed the IVF? I'll never know, but I wasn't going to wait till 38-39 to find out.
Crazy part is, I had a buddy who go the same script from the same doc of 200mg of Test Cyp; he was on for seven years straight. He was unable to get his fiancé pregnant, so I sent him to the same fertility clinic I went to. Doctor told him the same shit: get off everything. He got off, did what he was told ( think just HCG), and four months later got his wife pregnant.
This goes to show that fertility is also genetic. Hopefully, giving yourself more time, you will recover fully. But definitely drop all exogenous test.
