What is test tube baby

Test tube baby is to cultivate fertilized eggs and embryos in vitro, and then transfer the embryos back to the mother's womb, so as to develop into a normal fetus. At present, test tube babies are divided into three generations. The first generation of test tube babies is a traditional classic test tube baby, which takes the mother's eggs to form fertilized eggs with sperm in vitro, cultivates them into blastocysts, and then transplants them back to the uterus to develop into fetuses. Second generation IVF refers to the fertilization of single sperm, which is fertilized under the microscope to form a fertilized egg, which is used to treat infertility caused by the lack of sperm in the man. The third generation test tube refers to that 1-2 cells of in vitro embryos are taken for pre transplantation examination to exclude chromosome abnormalities or special gene abnormalities, and then the embryos are transferred into the uterus.

The world's first test tube baby was born in Britain in 1978. Test tube baby technology can help infertile couples who are still unable to conceive after routine treatment to obtain babies.
