>How long have they been present for? If more than a few years, then they can't be why, since the article says that 10 years ago, this wasn't a problem. I doubt I'll be able to reply to you, quite downvoted. In my source you'll find most dates are in the 2011-2013 era. Hence 10 years ago. The allegation that "10 years ago it wasnt a problem" is quite inaccurate. Most of these problem are occurring during pregnancy and pre-puberty. Whereas the damage is done, but then you have to wait some period of time until gender dysphoria really occurs. So it's completely a delayed action. So this absolutely is a factor. In terms of all endocrine blocker exposures. Some pre-exist 10 years ago like phytoestrogens in soy products; but most were greatly introduced about 10 years ago.
