Considering that FAT is the biggest producer of estrogen in the body
for me,
and if people stayed at the optimal weight, they'd be no moobs, I think
this is the kind of popular science I hate. Enzymes in fat convert
T into E.
For example,
There's no way you get big boobs even if you drank a 12 pack of beer a day
if you expended enough energy so the carbs are not stored as fat.
Phytoestrogens in food are known to exist for a LONG TIME, and even
if you take big doses (like some TS do), you don't get that much moobs.
The main impact of phytoestrogens is NOT moob's but fertility, which
is much more sensitive to estrogen's influence on the sex hormones pituitary feedback
loop (exogenous source of E cuts down the T production from the testes, just like you
would be if injecting or injesting, just to a much lesser degree).
