What does prenatal testosterone have to do with anything? So far I’ve learned that, apparently, it changes the index to ring finger ratio, changes facial features and even penis size. How true is all of that? Is research limited in that department?
Also what affects the amount of prenatal testosterone exposure? Is it purely genetic? Or are there environmental factors too?
