Beijing: A healthy baby girl was born in China from an embryo frozen 18 years ago, medical officials said on Wednesday.
A 45-year-old woman gave birth to a girl, weighing 3,300 gm, in Jiangsu province on Monday. The embryo was implanted into her womb in November 2015, Xinhua news agency reported on Wednesday.
She suffered from blocked fallopian tubes and tried to conceive through In Vitro Fertilisation (IVF) in 1998.
After three failed implantations, one with a fresh embryo and two with frozen, she decided to wait and try again.
At the beginning of 2015, she went back to the hospital hoping to have another try. Doctors found that she suffered from hydrosalpinx and a thin endometrium. After a surgery, she had the embryo implanted.
Frozen embryos are stored in liquid nitrogen at minus 196 degrees Celsius. According to the Shanghai health department, the storage life for frozen embryos should be kept within five years.
"In reality, we will continue storing embryos as long as the patients ask us to do," said a medical official.
