Thomas Beatie, the transsexual man who made headlines after becoming pregnant, has given give birth to a baby girl today.
The birth at a hospital in Bend, Oregon, was natural, according to a source, though earlier reports said that Mr Beatie planned to have a Caesarean section.
"She's really cute, really pretty," the source told ABC News.
Mr Beatie, 34, was born a woman - Tracey Lagondino - but had his breasts surgically removed and began taking males hormones several years ago.
He legally changed his gender, grew a wispy beard and married a woman but retained his primary female sexual organs so he could one day get pregnant.
His wife, Nancy had had a hysterectomy some years earlier.
Mr Beatie sparked an international furore in March after he announced he was pregnant. "I feel it's not a male or female desire to have a child," he later told Oprah Winfrey on US television.
"It's a human need. I'm a person and I have the right to have a biological child."
Before becoming pregnant, Mr Beatie stopped the testosterone injections he had been receiving for his sex change.
He and his wife bought donor vials from a cryogenic sperm bank and he was inseminated at home.
Doctors say Mr Beatie is not the first transgender man to give birth. Writing in March, he said: "I will be my daughter's father and Nancy will be her mother. We will be a family."

因怀孕而轰动全球的美国变性男子托马斯•比提于昨日顺利产下一名女婴。
尽管此前有报道称比提将选择剖腹生产，但据一位知情人士介绍，比提在俄勒冈州本德市的一家医院顺产生下女儿。
这位知情人士在接受ABC的采访时说：“孩子很可爱，也很漂亮。”
34岁的比提本是一名女性，名叫翠西•拉格恩蒂诺，但为了变成男性，她于几年前接受了胸部缩小术并开始注射雄性激素。
比提获得法律认可的男性身份后，与一名女子结了婚。变性后比提的下巴长出一小撮胡子，但他保留了最主要的女性性器官，所以才能怀孕。
比提的妻子南希多年前因切除子宫而无法生育。
今年三月，比提怀孕的消息在全世界引起轰动。后来他在接受奥普拉·温弗瑞（译者注：美国著名脱口秀主持人）的电视采访时说：“我觉得生孩子不只是男人或女人的愿望，而是人的需求。作为一个人，我有权拥有自己的亲生孩子。”
在怀孕前，比提停止注射用以维持男性特征的睾丸激素。
比提与妻子从一个冷冻精子银行买回精子，并在家接受了“人工受精”。
据医生介绍，比提并不是第一个怀孕生子的变性人。今年三月比提在一篇文章中写道：“我是女儿的父亲，南希是她的母亲。我们是一家人。”
