I would expect testosterone to prevent or reverse atrophy of the testes.
AAS (Anabolic/Androgenic) Steroids can cause testes to shrink because artificial testosterone is introduced into the body which causes the testes to stop producing natural testosterone. This is called testicular atrophy, usually after someone stops using the steroid the body will start to produce natural testosterone again after this testes should return to normal size.

Alcohol decreases testosterone levels by affecting hormone regulation between the brain and gonads.
Males- testes Females - ovaries (yes females have testosterone)
Leydig cells produce testosterone in the testes. They are also called interstitial cells.
Male reproductive system produces Testosterone. This hormone is produced by the interstitial cells of the testes.
The primary hormone produced by the testes is testosterone, which plays a crucial role in male reproductive tissues and secondary sexual characteristics.
