”IVF is the medical name for in vitro fertilization and embryo transfer, or IVF-ET, and includes a number of derivative techniques, such as intracytoplasmic sperm injection (ICSI), embryo freezing, and embryo-assisted hatching. The goal is to help infertile couples obtain a healthy child. During a normal pregnancy, the ovary expels an egg and the husband’s ejaculated sperm meet in the fallopian tube to form a fertilized egg, which is subsequently implanted in the uterus to develop into a fetus. When the sperm and egg meet in the fallopian tube, the number and vitality of the sperm are not sufficient, the egg is discharged, and the endometriosis and other pelvic factors are abnormal and the wife cannot conceive, artificial methods are needed to overcome these problems. In vitro fertilization and embryo transfer is a technique that simulates the process of fertilization and early embryo development in vivo to help infertile couples obtain a child. During the IVF process Sperm and eggs are collected separately and combined under laboratory conditions, with fertilization taking place outside the body. The fertilized egg is then transferred to the uterine cavity for further growth. IVF and ICSI are the same process except that the method of fertilization in the laboratory is different. ”IVF” is an artificial method of pregnancy assistance, used only when other methods have failed or are ineffective. Therefore, infertile couples must undergo a specialized examination and diagnosis in the fertility clinic and meet the indications for IVF treatment before they can enter the IVF procedure.
