Twins Joined Together
Mengele's obsession with genetics lead him to conduct some of the most horrific experiments upon small children. Mengele wanted to change the genetic traits of his captives. With twins, Mengele would draw out tubes upon tubes of blood from one twin and try to transfuse it with the other. This would leave both twins extemely sick and often lead to death. Mengele would sew twins together without anesthetics to make siamese twins. A popular experiement conducted was the removal of a child's reproductive organs to make a sex change.
