In vitro fertilization and embryo transfer (IVF-ET) is often called “in vitro fertilization” in our country. In fact, in vitro fertilization is a special technique in which both eggs and sperm are taken outside the body and allowed to complete the fertilization process in an artificially controlled environment outside the body, and then the early embryos are transferred to the woman’s uterus, where they are conceived as a child. Babies produced using in vitro fertilization techniques are called IVF, and these children also grow up in the mother’s womb. It can be said that “IVF technology” is equivalent to “in vitro fertilization”. Indications 1. Patients with tubal obstruction; 2.
