Dr. Paul R. McHugh, the Distinguished Service Professor of Psychiatry at Johns Hopkins University and former psychiatrist–in-chief for Johns Hopkins Hospital, who has studied transgendered people for 40 years, said it is a scientific fact that “transgendered men do not become women, nor do transgendered women become men.”

All such people, he explained in an article for The Witherspoon Institute,  “become feminized men or masculinized women, counterfeits or impersonators of the sex with which they ‘identify.’”  Source
