A South African woman has given birth to 10 babies in what could be a new world record.
Gosiame Thamara Sithole's husband says they were astonished by decuplets after scans only showed eight in the womb, report sthe BBC.
"It's seven boys and three girls. I am happy. I am emotional. I can't talk much," her husband Teboho Tsotetsi told Pretoria News after the birth on Monday night.
Sithole, 37, previously gave birth to twins, who are now six years old.
She is said to be in good health after delivering by caesarean section 29 weeks into her pregnancy in Pretoria on Monday evening.
Guinness World Records told the BBC it was investigating Sithole's case.
A woman who had eight babies in the US in 2009 currently holds the Guinness World Record for the most children delivered at a single birth to survive.
Last month, 25-year-old Halima Cissé from Mali gave birth to nine babies, who are reportedly doing well at a clinic in Morocco.
Multiple births involving more than three babies are rare and often the result of fertility treatments - but in this case the couple say they conceived naturally.
Speaking to Pretoria News a month ago, Sithole said her pregnancy was "tough at the beginning" and she had prayed for a healthy birth, with many a sleepless night worrying about what was to come.
"How would they fit in the womb? Would they survive?" she asked herself, but was reassured by doctors that her womb was expanding.
When it was thought she was carrying eight foetuses, Sithole was suffering leg pains and doctors found that two of the eight "were in the wrong tube".
"That was sorted and I have been okay since then. I can't wait for my children," she told the newspaper at the time.
Her husband also said he was over the moon, and felt like "one of God's chosen children. It's a miracle which I appreciate".
Only two sets of nonuplets had previously been recorded - but none of the babies survived more than a few days.
