Siri Hustvedt said this quote

We all start out the same in our mothers' wombs. We, all of us, when floating in the amniotic sea of our earliest oblivion, have gonads. If the Y chromosome didn't swoop in to act on the gonads of some of us and make testes, we would all become women. In biology, the Genesis story is reversed: Adam becomes Adam out of Eve, not the other way around.
