Thomas Beatie, who was born a woman but lives as a man in Oregon after surgery and hormone treatment, was the first man to become a mother. Thomas Beatie, 34, who is legally a man but kept female reproductive organs when he had a sex-change operation 10 years ago, made headlines around the world and was dubbed the "pregnant man" before giving birth to a baby girl on June 29. After giving birth he did not go back on the male hormone testosterone that he took after his sex change, because he wanted to have another baby. Beatie's wife, Nancy, 46, whom he married five years ago, was unable to conceive because of a prior hysterectomy. That is why he had a baby himself, through artificial insemination using donor sperm and Beatie's own egg.
