Thanks Dr. Crisler. Prior to coming under your care one week ago via defy medical, I had been on TRT under my primary since January of 2015. I had a sperm count test done a few months ago and the doctor said my results showed I was 100% sterile. You prescribed 150 of HCG daily, which I began on...
how long does it take for HCG to restore infertility due to TRT? I was very fertile but since being on TRT without HCG I'm completely sterile. I have been on HCG for 1 week and am wondering when I should expect to be fertile again.

Understanding Your Hormones
Estradiol (E2)
A form of estrogen produced from testosterone. Important for bone health, mood, and libido.
Too high can cause side effects; too low can affect well-being.
DHT
Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth,
prostate health, and masculinization effects.
Free Testosterone
The biologically active form of testosterone not bound to proteins.
Directly available for cellular uptake and biological effects.
