IVF is a method of artificially assisted conception in which an egg and sperm are fertilized outside the body to form an embryo, which is then transferred into the mother to continue the pregnancy. Clinically, there is no limit to which three types of women cannot do IVF, but women with some diseases cannot do IVF, such as amenorrhea, active infectious diseases, acute infectious diseases, hereditary or psychiatric diseases, reproductive organ damage or malformation, serious systemic diseases, etc. 1. amenorrhea: after women have amenorrhea, they usually no longer ovulate, and even if they ovulate, the quality of eggs is poor, so they have a higher chance of miscarriage after doing IVF. 2. The chance of miscarriage is higher after IVF; 2. Active infectious diseases: during active infectious diseases, such as acute and chronic hepatitis or sexually transmitted diseases, IVF will contaminate the laboratory environment and increase the risk of infectious disease transmission, and even if the pregnancy is successful, it will increase the chance of mother-to-child transmission, so IVF cannot be done; 3. Acute infectious diseases: if women have acute infections of the reproductive and urinary systems, etc. The presence of hereditary or psychiatric diseases may be passed on to the fetus, which is not conducive to eugenics, and the long-term use of drugs for such diseases is also not conducive to embryonic development. If the embryo cannot grow and develop normally in the uterus because of the absence of the uterus, severe uterine adhesions, vaginal atresia, etc.; 6. Serious systemic diseases: some serious systemic diseases may cause women to be unable to tolerate pregnancy or may be detrimental to fetal growth and development, such as hyper- or hypothyroidism, uncontrolled hypertension, diabetes, serious heart disease, liver and kidney disease, and even malignant tumors of the uterus, ovaries or breast, etc., which can increase the risk of pregnancy and threaten the health of mother and child. The above list shows some of the women who cannot undergo IVF, and IVF is also not recommended for women who have bad habits such as alcoholism or drug addiction, as well as those who have long-term exposure to harmful substances such as radiation and chemical toxins. In addition, it is recommended that both men and women undergo relevant physical and laboratory examinations before IVF to exclude contraindications and ensure normal fetal development.
