Female egg retrieval is harmful to the body, and may lead to pelvic infection, ovarian hyperstimulation syndrome, damage to neighboring organs and other hazards. 1. Pelvic Infection: Egg retrieval involves puncturing the ovaries, which will leave a wound on the ovaries. If the environment of egg retrieval is not up to the standard of bacterial overload, it may lead to infection of the reproductive tract, causing pelvic inflammatory disease, which will jeopardize the health of the woman and her fertility in the future. 2. Ovarian Hyperstimulation Syndrome: Women have to take ovulation stimulating drugs during egg retrieval, due to the different sensitivity of individuals to drugs, the degree of sensitivity to ovulation stimulating drugs is also different, and some women will experience discomfort after taking ovulation stimulating drugs. In addition, the ovaries may be overstimulated by the outside world during the process of egg retrieval, which may cause ascites, abdominal distension, nausea and vomiting, enlarged ovaries, respiratory difficulties, and other ovarian hyperstimulation syndrome and other uncomfortable phenomena. 3. Damage to neighboring organs: although the egg extraction surgery is simple, there are surgical risks, the process of egg extraction may damage neighboring organs, such as intestines, ureters, bladder and other organs, resulting in damage to the body. Women must go to a regular hospital for egg retrieval, and pay attention to body care after egg retrieval to avoid infection and sequelae.
