A Nigerian woman living in Texas, US becomes the mother of sextuplets after giving birth to two sets of twin boys and one set of twin girls in under 10 minutes at The Woman’s Hospital in Houston.

The babies were all born in nine minutes, between 4:50am and 4:59am, the hospital reportedly said in a statement.

It was not stated whether the babies were delivered naturally or through a caesarean section operation.

The delivery team, led by Dr Ziad Haidar, Dr Sharmeel Khaira and Dr Israel Simchowitz, said mother Thelma Chiaka was doing well.

According to The Houston Chronicle, the babies were born at weights ranging from 1 pound, 12 ounces (794 grams) to 2 pounds, 14 ounces (1.3 kilograms).

They were said to be in a stable condition in the hospital’s advanced neonatal intensive care unit.

Ms Chiaka named her twin daughters Zina and Zuriel, The Chronicle reported.

She was still reportedly working on names for the four boys.

The Woman’s Hospital said the odds of having sextuplets were estimated at one in 4.7 billion.

A statement from the hospital said:

“The Woman’s Hospital of Texas, an HCA Houston Healthcare Affiliate, which delivers more babies than any other Texas hospital, early [Friday] morning welcomed sextuplets, the odds of which are estimated at one in 4.7 billion.”
