Britain's Hayden Cross, who has been legally male for three years and had paused his sex transition to have a child, recently given birth to a baby girl.
The 21-year-old made headlines around the world when he announced he was pregnant by a sperm donor.
His daughter Trinity-Leigh was born by caesarean on June 16, his family confirmed.
"She's perfect in every way," he told The Sun.
Now, he plans to complete his gender re-assignment to remove his breasts and ovaries.
Cross was born in Paige and had applied to have his eggs frozen on the NHS in the hope that he would have children in the future, but when he was refused, he found an anonymous donor through a Facebook group.
"Having a biological child has always meant a lot to me," he said earlier this year. "I've always wanted kids."
His daughter was born at Gloucestershire Royal Hospital in the Britain, with Cross was registered as mother but not the father.
He also received death threats after she broke the news of his pregnancy.
