Aromatization at different body fat %

I'm wondering if anyone has experiences or data on the effect of different levels of body fat on aromatization.

Right now I'm 18-19% body fat, and I'm wondering if I drop to 10-12% how much that will reduce my E2 if I kept my TRT dose constant. For example, if I drop from 19 to 11% body fat, that's a 42% reduction. Would my E2 also drop by 42%? That would bring a 60 pg/mL E2 down to 35 pg/mL. Or is not directly proportional that way?

What do you predict would happen to E2 if it was 60 pg/mL at 19% BF and I dropped to 11% BF, keeping other variables constant?

Good question. And why is the body fat producing estrogen and yielding the supposed spill over of estrogen.

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.
