Baby born from embryo frozen 12 years ago
A healthy baby was born in northwest China’s Shaanxi province from an embryo frozen 12 years ago, a record on the Chinese mainland.
On Feb 24, a 40-year-old woman gave birth to her second son at Tangdu Hospital in provincial capital Xi’an.
She suffers from blocked fallopian tubes and polycystic ovary syndrome, which can affect a woman’s fertility and pregnancy. She began trying to get pregnant through IVF in 2003.
That year, doctors harvested 12 of her eggs and created 12 embryos with her husband’s sperm. They implanted two fresh embryos into her womb, and froze the remaining seven that they considered viable.
Li gave birth to a healthy boy in 2004, and has since spent three yuan (around 50 cents) per day to store the embryos in the hospital in case of an emergency. Last year, when China dropped its one-child policy, she decided to have a second child.
Three embryos survived the thawing process. The two best were implanted in her womb, but only one survived.
