You will run across many orders of magnitude more plastic lechate, pesticide, and herbicide than you will of pharmaceutical estrogens unless you are taking them. They don’t even double the quantity excreted by women taking them as contraceptives, so the main exposure route is barely affected.
I STRONGLY suspect it has a lot to do with xenoestrogen and endocrine disruption effects from plastic and rampant pesticide/herbicide use.
