I know that the older generation of birth control pills contained estradiol, which is a for-sure endocrine disruptor. And it isn't well broken down by city waste-water treatment systems, so it gets into the discharge effluents bigtime and ends up queering the aquatic vertebrates, e.g. egg proteins appearing in the testes of male amphibians and certainn piscene species, in short, "freaky fish."
But the newer genertion of pills--- and also the day-after pills like "ella" and "Plan B" ---- I'm not so sure.
Anybody know?
