Is Gender Fluidity a result of Environmental Toxins

It seems likely. There’s several studies

An endocrine disrupting chemical, bisphenol A: could it be associated with sex differentiation in brain regarding to transsexuality?”

Transsexuality presume a combination of a genetic background and an early effect on interaction of sex hormones with developing brain during critical foetal period. We hypothesize that exposure to BPA may be a cause for transsexualism.

Gestational exposure to phthalates and gender-related play behaviors in 8-year-old children: an observational study

Higher maternal urinary MEP concentrations during pregnancy were associated with more typical gender-related play behaviors in both males and females, and increased urinary MiBP concentrations were associated with less masculine gender-related play behaviors in males. (more female?)

Teen hormones being altered by gender-bending chemicals

Members of the ECA committee warned that BPA can disrupt the body’s endocrine system, which is the collection of glands that produce hormones.

Maternal bisphenol A (BPA) decreases attractiveness of male offspring

Authors show that maternal consumption of low levels of dietary BPA renders male offspring at a disadvantage for mating, not only because of poorer spatial navigation and greater anxiety-like behavior but also because they are less attractive to female conspecifics

There are many more studies on relationships between endocrine disruptors, fertility, vaginal cancer, diabetes, its all bad.
