I heard a segment on some talk radio just this week about the increasing frequency of girls as young as 7 developing breast tissue, signaling the beginning of puberty. 7! They offered no cause.
It's very complicated.
“..girls as young as 7.. They offered no cause.”
Seems like I read somewhere about a link to prior use of birth control pills by the mother. Her body’s hormones are overloaded and out of whack, that even after she stops taking them and becomes pregnant, residues remain in her blood and endocrine system. These hormonal residues might pass into the fetus in utero.
IIRC, the study claimed the result was early puberty in girls, and gender dysphoria in boys.
I’ve read other studies that claim oral contraceptives pass into the water supply and can cause a host of health problems to humans and wildlife.
