Canadian woman delivers identical quadruplets

Girls were born two months early, but are listed in good condition

HELENA, Mont. - A 35-year-old Canadian woman has given birth to rare identical quadruplets, hospital officials said Thursday.

The babies were born about two months early and were conceived without fertility drugs, he said. They weighed between 2.6 pounds and 2.15 pounds.

The chances of giving birth to identical quadruplets is about one in 13 million, Key said.

Medical literature indicates there are less than 50 sets of identical quadruplets, said Dr. Jamie Grifo, director of the NYU Fertility Center in New York.

The last reported set were born in April 2006 to a 26-year-old Indian woman.
