Mr Beatie said it had been his dream to one day have a child
An American man who was born female but subsequently underwent gender reassignment has given birth to a girl, US media have reported.
Thomas Beatie, 34, is legally male but kept his female reproductive organs after having breast surgery to remove glands and flatten his chest.
Both Mr Beatie and his daughter are reported to be doing well in a hospital in Bend, Oregon.
He was inseminated using sperm from an anonymous donor.
The birth was natural, a source at St Charles Medical Center in Bend told ABC News, and took place on Sunday.
Mr Beatie, who sports a wispy beard, made headlines around the world when he revealed in April that he was pregnant.
He told chat show host Oprah Winfrey it had been his dream to one day have a child.
"I opted not to do anything with my reproductive organs because I wanted to have a child one day," he said.
Mr Beatie grew up in Hawaii as Tracy Lagondin and was a Girl Scout, model and finalist in a teenage beauty pageant.
He began to live as a man when he was in his 20s and officially changed his gender, he told People magazine.
He has been married for five years to his wife, Nancy.
Mr Beatie's obstetrician, Dr Kimberly James, told Oprah Winfrey in April: "This baby is totally healthy. This is what I consider a normal pregnancy."
