My latest labs are total test 612 ng/dl and free 17.69 ng/dl. I do not do TRT but do use daily Cialis 5mg . Few weeks ago and on occasion morning wood and really good election quality and high libido. Then I go thru a phase of no morning wood lower libido . I take 50 mg zinc per day and I am wondering if this could be cause of potential low E? Have not ever had E test done before.
 
I never heard zinc affecting your libido or wood. Some use it to keep there estrogen in check. I use Jarrow Formulas, Zinc Balance. 15 mg Zinc (L-Monomethionine)
1 mg Copper, I take it twice a day.

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.
