HOUSTON: An American woman beat the odds of one in 4.7 billion after giving birth to sextuplets at The Woman's Hospital of Texas in the United States, international media reported.

According to the hospital, the woman delivered two sets of twin boys and one set of twin girls between 4:50 am and 4:59 am local time Friday. The mother, Thelma Chiaka, is doing well. The babies were born at weights ranging from 1 pound and 12 ounces to 2 pounds and 14 ounces. They are stable and will continue to receive care at the hospital's advanced neonatal intensive care unit, according to the hospital statement.
