Hey, I have been reading threads thru out the years since I've been on TRT. I appreciate everyone's advice and stories of their own. However, I haven't seen a question like mine.


I have three children and after my youngest was born, 4 years ago, I began to experience low T symptoms. After blood work the doctor decided to start me on TRT.


After being on TRT for three years my testicles shrunk and I am long producing sperm. My wife and I decided to try for another child. In knowing this my doctor placed me on HCG 3 months ago. The dose is 2000 i/u every other day in conjunction with my testorsterone which is 200 mg every other week.


Is it possible to start producing sperm again while on TrT, or do most men get completely off?


Any advice?


I have noticed the size of my testes have doubled since I have taken HCG.

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.
