The Man Who Would Be Queen: The Science of Gender Bending and Transsexualism is a 2003 book by J. Michael Bailey, published by Joseph Henry Press. In it, Bailey reviews evidence that male homosexuality is congenital and a result of heredity and prenatal environment. He also reviews evidence for the theory that there are two forms of transsexualism, one that is an extreme type of homosexuality and one that is an expression of a paraphilia known as autogynephilia.
