Thought I would start by commenting how much I appreciate the wealth of medical advice and direction this forum gives. I started searching for answers when my Primary Care PA stated that she did not know what SHBG was on a routine detailed blood test I had done back in May 2014. It was 101!. My total T was 743 which any normal doctor was say it was in the high range. Testosterone Percentage Free was 1.0, Free T was 7.24. I then went to 3 other MD's, one an Endo and he said there was nothing wrong with high SHBG!. What?

After reading 4 books including Nelson's book, I started looking for a MD who knew how to treat low T. Found a clinic near me but, the MD didn't test Free T or Estradiol Sensitive. After trying pellets from Nov 2014 to Oct. 2015, I am now with Dr. Saya and nurse Jill at Defy and couldn't be happier.

Again, thanks to Nelson and all the experts!

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.
