Cohorts of US women and girls between 1950 to 2005 show significant earlier #menarche with more girls menstruating for the first before age 11.

Higher body fat percentage or BMI may be factors, but also possible is environmental exposure to #endocrine-disruptive chemicals.

Reading this🧵? Your blood probably contains some amount of toxic #foreverchemicals made by #3m

Enough to spike your risk of cancers & illnesses?

Without a blood test, you have no idea.

Why is their toxin running in your veins?

Well, 3M & #dupont kept the harms secret even as their toxins were incorporated into...everything.

From french fry bags to chairs.

They gaslit their own scientists.

& regularly dumped, creating toxic zones. 1/

If transmasculine people taking testosterone experience improvements in their long covid symptoms, and transfeminine people taking estrogen experience the opposite, then the way sex differences in covid presentation are talked about need to include these realities. Sex is a multidimensional phenomenon and the endocrine system is a malleable thing

1. "Since the 90s, researchers who are trying to understand the accelerating increase in reproductive problems have focused on endocrine disrupting chemicals. #Endocrine disruptors include:

Phthalates, chemicals used to make #plastics more durable, found in 100s of products—from vinyl flooring to lubricating oils & personal-care products (soaps, shampoos, & bhair sprays)
#Pesticides & herbicides, including glyphosate, the world’s most widely used weed killer
Bisphenol A (BPA) & phenol, common in food storage materials
Polychlorinated biphenyls (PCBs) & brominated flame retardants, used in electronics & building materials
Per- & polyfluoroalkyl substances (#PFAS), “forever chemicals” used as oil & water repellents & coatings for common products including cookware, carpets, & textiles.
PFAS endocrine disrupting chemicals have been found in the remotest locations on the planet, and they contaminate up to half the US #water supply."
