TW: mention of living child, pregnancy & pregnancy loss/ stillbirth

Those who have experienced azoospermia due to testosterone replacement therapy:

Are there any supplements and/ or RX medications that men can take to help the side effects of low T?

A little background: we have been pregnant 4x and have one living child who is 4, a stillborn baby in august of 2020 (completely unrelated), and two miscarriages. My last miscarriage was in October of 2021. Fast forward to October of 2022, we got the DX of zero sperm count. My husband has been on TRT the entire time (his last pellets were May of 2022). He's tried Fertilaid, has taken Clomid and done hcg shots. He's feeling the side effects of low T (he is 35 and without TRT his testosterone is in the 200s). Side effects are exhaustion, brain fog, low libido, and depression.

Any pointers on what he can take to help him feel better? He does exercise & eat well. Any success stories or positive words would be amazing. This has been a long journey of 2.5 years.

ETA: I met with our fertility doc today and he ordered labs & another semen analysis.
