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”. Who can undergo IVF III? 1. Common chromosomal disorders such as chromosomal number and structure abnormalities in both partners, including Roche translocations and mutually balanced translocations. Some translocations are not diagnosable, please consult your doctor after consultation. 2. Common monogenic genetic disorders. Such as thalassemia, progressive muscular dystrophy, etc. 3.Children with chromosomal disorders (such as trisomy 21) have been born, and both spouses have normal chromosomes. 4, The female partner is of high reproductive age and may choose to screen embryos for aneuploidy depending on ovarian function and the number of follicles (high age may produce aneuploid embryos, which is one of the causes of miscarriage and congenital stupidity).
