E2 Standard vs E2 Sensitive

Yes! And, for now, I am attempting to do just that. In the past I was trying to compare labs from the VA, LabCorp or Quest...=( Looking forward to hopefully attaining a somewhat stable range so I can actually compare symptoms with labs! Spent a lot of years riding this hormonal roller coaster, so don't expect it to get corrected anytime soon...one day at a time! Sad because I have several senior friends that seem to be lost in this stage of andropause. None of them even know what their lab results are!? If I can get my system stabilized and functioning within reason, then maybe I can convince them to find a knowledgeable Dr/Clinic and get some help! Blessed to have found this site... Roy

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.
