A US woman with a rare double uterus has given birth twice in two days – after a ‘one in a million’ pregnancy and a total of 20 hours in labour.
Kelsey Hatcher, 32, delivered one daughter on Tuesday, and a second on Wednesday, at the University of Alabama at Birmingham (UAB) Hospital.
Announcing the arrival of her ‘miracle babies’ on social media, Ms Hatcher hailed the medics as ‘incredible’.
Ms Hatcher said the family was now back at home and could ‘enjoy the holidays’. She had previously expected a Christmas due date.
The mother was told at age 17 she had a double uterus (uterus didelphys) – which the UAB described as a rare congenital anomaly affecting 0.3% of women.
The odds were against her
And the odds of becoming pregnant in both uteri – a dicavitary pregnancy – were even slimmer, at ‘one in a million’, according to the UAB.
Reported cases worldwide are extremely rare. In 2019, a doctor in Bangladesh told the BBC a woman had given birth to twins almost a month after delivering a premature baby in her other uterus.
Ms Hatcher had three previous, healthy pregnancies. This time, she believed herself to be pregnant in only one uterus – until a routine ultrasound revealed there was also a baby in her second.
‘I gasped… We just could not believe it,’ she recalled.
It was not a typical twin pregnancy
Prof Richard Davis, who co-managed the delivery, pointed out that each baby had enjoyed ‘extra space to grow and develop’.
This was because each baby had a womb to itself, he said – unlike in a typical twin pregnancy.
Ms Hatcher’s labour was induced at 39 weeks, and required double the monitoring and charting at the hospital – as well as double the staffing.
Her obstetrician described ‘a cheer from everyone in the room’ when the first baby was delivered vaginally at about 19:45 local time on 19 December.
The second came by C-section more than 10 hours later, at about 06:10 the following morning.
What is fraternal twins?
Prof Davis said the girls could be called fraternal twins – a term used when each baby develops from a separate egg, each fertilised by a separate sperm.
‘At the end of the day, it was two babies in one belly at the same time,’ he said. ‘They just had different apartments.’
