Sir my one testicle got injured n stopped working when I was around 16.Due to shyness I didn't tell anyone.Initially I was doing fine with one testicle and it was normal but gradually over the years my energy n overall wellness being going down Now I'm 22 but I've features of 18 yr old.I feel like half a man and I'm suffering.Symptoms - Very low energy - feminine body - no chest hair,few pubic hair - very low confidence - no morning wood Iv e attached a picture of my body type I've researched about SERM's n TRT a bit. I'm in need of help. Can increase in testosterone through SERM or TRT increase growth hormones levels. What should I do in terms of finding a doctor and which doctor should I see Thanks a lot sir
