I spent 16 years in cryopreservation an embryo transplanted to a Chinese woman. The woman gave birth to a healthy child - a boy. The birth of a 46-year-old woman took place in early February 2017 at the first clinic at Sun Yatsen University in Guangzhou, according to the Chinese South China Morning Post.
The woman's first son was also conceived using IVF - in vitro fertilization. Her first test-tube baby was conceived in 2000. The second child of a resident of the Chinese province of Guangdong was born from the same group of 18 embryos, from where the frozen embryo of her first son was taken for IVF.
IVF is an assisted reproductive technology most often used in cases of infertility. Its synonyms are artificial insemination or in vitro fertilization, RIA Novosti recalls.
During IVF, the egg is removed from the woman's body and artificially fertilized in a test tube. The resulting embryo is kept in an incubator, where it develops within 2-5 days. After that, the embryo is transferred to the uterine cavity for further development.
