Not sure this has been mentioned before on this forum, but I'm putting this information from my endo out there for all to know.
I know that there are quite some guys afraid that the T in their bodies is converted into E. It is usually mentioned that this happens when your T-levels are too high.
My endo could tell me that T is always converted into E. This is why cis-males have (low) levels of E at all times. She could also tell me that indeed, the higher your T levels, the more was converted into E because obviously there was more T to convert. She could also tell me that this happens in the fat of our bodies. Frankly, the more fat you have, the more T can be converted into E. So if you have relatively high T levels, and are on the heavy side, chances are bigger that T is converted into E.
The more we know about the processes going on in our bodies, the better.
