this correlates to the proliferation of endocrine disrupting chemicals in the food and water supply

If you remove fats from the sample size the only consistent item will be microplastics (xenoestrogens) and sneed oils that are destroying testosterone.

Obesity really fricks up hormones and it's the most likely cause. Chemicals and micro plastics probably aren't good, but their effects are still a little esoteric compared to how much we understand obesity fricks up your body and exactly how many people are obese with fricked up hormones.
I bet too the fatter you are the more likely to have microplastics in your body.
Doctors and scientists will find absolutely anything before blaming obesity these days, it's fricking nuts.

This. Too much """vegetable""" oil, corn syrup, alcohol, and cigarettes decrease testosterone drastically, since xey all contain phytoestrogens thus making you less masculine
