Not completely sure what you mean by "estrogenic puberty" because it doesn't show up in a Google search. However, "estrogen puberty" does, which I assume you're referring to, and is a condition in females. But in looking up "
estrogen puberty in males," which I assume you're really referring to, I find that:
"Guys have mostly androgens in their systems, but they also have small amounts of estrogen. In girls, breast growth is caused by high levels of estrogen. Normally, when going through puberty, a guy's production of androgens increases greatly, whereas estrogen production remains low.
However, sometimes guys produce enough estrogen during puberty that some breast tissue develops. Breast tissue growth in guys can appear on one or both sides of the chest, and the breast area can feel tender.
This doesn't mean a guy is turning into a girl or anything. It's just a
minor change in hormones as he begins to grow into adulthood."

To which I can only say, so what? Do you think that higher than normal amounts of estrogen during puberty in a male leaves him no stronger than a female? If so, you'll need to produce the evidence.
Then there's the fact that estrogen levels play next to no role in gender identity formation---gender dysphoria, a mental state, being the issue with transgender identity---making it all a moot issue.
