Serum Estrone (E1) vs Estradiol (E2)

I just had some labs done - my Seum Estrone came back high at 126! The range is 15-65.
Meanwhile, my Estradiol is also high at 44.2 (range is 7-42).

What the heck is the difference between Estrone and Estradiol?

I'm on hCG mono - I had crashed my E by taking Letro, so I've cut back on that to let it recover.

Thanks!

Estrone is e1 and estradiol is e2. There is also a third estrogen. e2 is the one that effects us the most, so it’s really the only one that usually needs to be monitored.
 
Estrone is supposed to be more pro-cancer. E3 is Estriol and is supposed to be more cancer preventative.

To take it further, I was told that it's the metabolites of Estrone which can be pro-cancer. I take DIM which is supposed to alter the mix of these metabolites.

An aromatase inhibitor should drop E1 as well as the other E's.

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.
