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”. IVF is an assisted reproduction method in which embryos are formed by in vitro fertilization and transferred into the uterine cavity. Indications: 1. Gamete transport disorders due to various reasons. 2. Ovulation disorders. 3. Endometriosis, etc. 4.Low sperm, weak sperm, teratozoa. 5.Immune factors. 6. Infertility of unknown cause. The process of IVF is complicated. Egg retrieval is performed when the follicles are mature and transfer is performed at the appropriate stage of embryo culture. Therefore, it is important to follow the doctor’s orders for examination and medication in order to ensure the effectiveness of the treatment.
