The world's first test-tube baby has given birth to a child of her own, according to reports.
But Louise Brown conceived her baby, thought to be a boy, naturally, according to the Sun.
Her husband, security officer Wesley Mullinder, 37, was said to be thrilled at the birth.
The newspaper said the new mother was she was spotted with a carrycot outside her Bristol home and quoted a friend as saying the couple were "over the moon".
It reported that 28-year-old Ms Brown had previously said: "We'd love to have children of our own and - hopefully - we won't need to use IVF."
Mr Mullinder had previously told of the couple's excitement when they found out they were to become parents.
He said: "Louise will make a fantastic mother."
Ms Brown's birth, on July 25, 1978, created headlines throughout the world and followed a decade of research on finding ways to fertilise human eggs outside the body.
She was born by Caesarean section at the Royal Oldham Hospital thanks to the efforts of Dr Robert Edwards, who jointly invented the IVF technique that led to her birth, and the late Dr Patrick Steptoe, a gynaecologist at the hospital.
Mr Mullinder met his wife in 2002 at a Bristol nightclub where he worked as a doorman. The couple wed in 2004.
