The bad effects of IVF on the mother include ovarian hyperstimulation syndrome, multiple pregnancies, puncture injury, psychological damage, etc. 1. Ovarian hyperstimulation syndrome: ovulation induction drugs can lead to multiple follicle development, excessive estrogen levels, etc., causing increased vascular permeability throughout the body, blood levels into the body cavity, leading to abdominal distension, abdominal fluid, pleural effusion, electrolyte disorders, thrombosis of vital organs, and in severe cases, can lead to death. 2. Multiple pregnancies: Multiple embryo transfers can lead to an increased incidence of multiple pregnancies, which can easily lead to miscarriage, preterm labor, and increased complications during pregnancy. 3. puncture damage: puncture during IVF egg retrieval can cause complications such as ovarian emergence, infection, and uterine perforation. 4. Psychological damage: IVF is prone to miscarriage, embryo arrested development, fetal malformation, repeated embryo transfer, pain during puncture, etc., which causes psychological damage to women. Therefore, IVF needs to visit a regular fertility center and operate under the guidance of a professional doctor to minimize the harm caused to women.
