The hazards of IVF for women mainly include the following: 1. ovarian hyperstimulation syndrome: when IVF is performed, women have to apply more ovulation-promoting drugs, which can lead to ovarian hyperstimulation syndrome due to excessive use of ovulation-promoting drugs, causing abdominal distension, abdominal pain, ascites, and even gastrointestinal reactions, resulting in nausea and vomiting. In severe cases, it can also lead to the development of hydrothorax in women, which can even cause the formation of local blood clots and endanger women’s lives; 2. Cancer: due to excessive use of ovulation promotion drugs in women, it can lead to endocrine disruption and increase the chance of breast cancer or uterine adnexal tumors; 3. Inflammation: the process of implanting the gestational sac can cause an increased chance of local infection, causing special inflammation inside the intrauterine fetus and uterus; 4, Others: When IVF is performed, multiple gestational sacs are implanted inside the woman’s uterus, which in turn leads to multiple pregnancies, increasing the risk of disease during pregnancy and causing some damage to the body.
