IVF is an artificial operation, which may cause certain hazards to the mother’s body, such as the stimulation of the injection site by the application of ovulation stimulating drugs, overstimulation of the ovaries, damage to the pelvic organs, and so on. 1. Stimulation of injection site: before and after IVF, a large amount of drugs will be injected into the pregnant woman, which may cause certain stimulation to the skin and muscle of the injection site, resulting in abnormalities such as local skin allergy, edema and hardness. 2. Overstimulation of ovaries: In the process of ovulation stimulation treatment, a large number of follicles will develop, which may cause ovarian hyperstimulation syndrome, which in turn will cause nausea, loss of appetite, abdominal distension, abdominal pain and other symptoms. 3. Damage to pelvic organs: During the process of egg retrieval by puncture, the peripheral organs such as ovaries, bladder and rectum may be damaged. If the blood vessels in the pelvic cavity are damaged, it may also cause intra-pelvic hemorrhage or even hemorrhagic shock and other hazards. If a woman experiences the above symptoms after undergoing IVF, it is recommended that she consult a doctor in time, and under the doctor’s guidance, improve the relevant examinations to clarify the cause of the disease and treat the symptoms.
