Annegret Raunigk, a 65-year-old teacher from Berlin, has given birth to quadruplets after a pregnancy that was made possible through artificial insemination.
Raunigk gave birth to a girl named Neeta and three boys whom she called Dries, Bence and Fjonn through a cesarean section at a Berlin Hospital, according to AFP. The infants were born prematurely at 26 weeks and weighed between 655 grams (1 lb., 7 ounces) and 960 grams (2 lbs., 2 ounces) each.
Germany's RTL television noted that the babies have a "good chance of surviving," but added that possible complications might occur because they were born premature, BBC News reported. Raunigk, however, is doing well.
Raunigk's pregnancy is a result of fertility treatment in Ukraine and has been the subject of fierce debate in Germany.
The single mother already has 13 children and decided to get pregnant again because her 9-year-old daughter wanted a younger sibling. She also has seven grandchildren.
She told German newspaper Bild that she wasn't concerned about the possible health risks for a woman her age.
"I simply assume that I will remain fit and healthy," she added.
Despite criticisms, Raunigk defended her decision, saying that those who don't agree with her "can see it how they want to, and I'll see it the way I think is right."
