For several decades female hormones have been added to processed foods. Soy contains plant based estrogen. Soy oil has been added to many processed foods, soy milk is favored in coffee, soy lecithin is in plant based meats. Over time this feminizes males, hence the term soy boy. The did mouse studies to learn this effect, then applied it to humans. I refuse to consume soy products because that estrogen triggers sore breasts, heavy menstruation with cramps and other harms. Diet is a big part of the “gender confusion” of males.
