Romanian hospital officials say a 67-year-old woman in Bucharest has given birth to a baby girl.
Adriana Iliescu, who had undergone fertility treatment for nine years before becoming pregnant, is thought to be the oldest recorded mother.
The girl was born prematurely by Caesarean section after her twin sister died in the womb, the hospital said.
Mrs Iliescu told local television she had always wanted to be a mother but had been unable to conceive naturally.
A spokeswoman at the Giulesti Maternity Hospital in Bucharest said the surviving infant weighed just 1.4kg (3lb) and was still in intensive care, but breathing normally.
"The mother is doing well. She is saying she has been given a new lease of life," the spokeswoman said, according to the Associated Press news agency.
Mrs Iliescu, a retired university professor, was interviewed by Realitatea TV last month.
She told the station she was optimistic about her future as a mother, claiming her family had a history of longevity.
In 2003, a 65-year-old Indian woman gave birth to a boy.
Schoolteacher Satyabhama Mahapatra from Nayagarh in Orissa had been impregnated with an egg from her 26-year-old niece that had been fertilised by her husband.
It was the first child for Ms Mahapatra and her husband, who had been married for 50 years.
