This would have made a great sci-fi novel 30 years ago. Who would have have ever imagined this would one day be reality?
And we look back and judge that last century's practice of lobotomizing violent criminals was considered cruel and unusual. I can't imagine what history will say about this.
Researchers and the USG have been worried since the 1960s that hormones and synthetic chemicals similar to hormones or that block them, could cause extensive animal and human gender dysphoria.
For example, phytohormones are sprayed on plants and given them with their fertilizer to increase size, yield and many other things. And some of these are very similar to their human hormone analogs.
While research didn’t show any *extensive* effect of these chemicals on people, it couldn’t prove that it would not affect people with other hormone or developmental problems.
A perhaps larger problem are human hormone supplements that are consumed then excreted in the urine, but are not destroyed or neutralized during water treatment, so are recycled into drinking water.
