This still sounds concerning to me, if the dose is 2mg for a healthy adult what is it for children and infants? What about babies in the womb? We saw the same exact thing with PFAS/PFOA, the experts said it was harmless, present in impossibly small quantities, and it would "pass right through you" for literally years. But then it turned out the experts were completely wrong. They found 2000PPM of PFAS in my Mom's wel…

2000 PPM is 0.2% or one-in-fivehundred, right? That’s massive pollution. My layman’s logic would suggest you need to dump 0.2% of total aquifer volume of 100% PFAS to reach that level? And then I expect pollution to spread in a semi-sphere unless there are rocky sediments. Edit: thinking more about water, perhaps you can dump less in wetter conditions and then in a drought get higher values because PFAS won’t evapora…

Apparently everyone is downvoting everything they can because this is a sensitive topic. I'd just like to call out, where feminization is a major concern (US, maybe Europe), there is less than 1ng/L of this compound in water, see elsewhere on this thread for the graphic. The lowest dose of EE2 for trans-women is 2mg a day orally. That means whatever the dosage is in the US it's less than 1/10th* of what trans folk fi…

Trans women typically take E2 (bioidentical estrogen), not EE2. EE2 is 100 times more potent than E2 for certain endocrine interactions. Unlike E2, EE2 is not a naturally occurring hormone. E2 causes female puberty when administered to males (except for menstruation), but EE2 isn’t necessarily going to do the same thing because it is a different molecule. While worrying about “feminizing” is probably hype, worrying a…

I'm concerned this is making numbers here because of fear mongers so I want to run the numbers a bit to > The top 10 countries ranked in the order of high to low average EE2 concentration in surface water, were Vietnam, Cambodia, China, Laos, Brazil, Argentina, Kuwait, Thailand, Indonesia and Portugal, with the respective mean concentrations of 27.7, 22.1, 21.5, 21.1, 13.6, 9.6, 9.5, 8.8, 7.6 and 6.6 ng/L Going by Wi…

There nothing right wing about this concern. As a progressive man I don’t want to be feminized, it’s terrifying, both at the personal and species level.

Hormonal disruption does, though.

It's common folk knowledge in my trans community that HRT often stops or in some cases partially reverse hair loss. See [1] for a case study, for example. Testosterone is correlated with hair loss and I could see how increasing T would worsen it, but blocking testosterone and increasing estrogen does have the opposite effect. 1: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5367483/
