'Until I was eleven or twelve, I didn't realize there was a second set of labia on the inside, since you couldn't see them. What's even funnier is that I thought urine came out of the clitoris…. When you're standing up, all you see from the front is hair. Between your legs there are two soft, cushiony things, also covered with hair, which press together when you're standing, so you can't see what's inside. They separate when you sit down and they're very red and quite fleshy on the inside. In the upper part, between the outer labia, there's a fold of skin that, on second thought, looks like a kind of blister. That's the clitoris.'
Before the war, Mengele had received doctorates in anthropology and medicine, and began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943 and assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. His subsequent experiments focused primarily on twins, with little regard for the health or safety of the victims.
