The advantages of hysteroscopy prior to embryo transfer are that it allows for adequate assessment of the intrauterine situation and improves pregnancy rates, while the disadvantages are that it can cause cervical injury, etc. Hysteroscopy prior to embryo transfer can provide a more visual and accurate view of intrauterine lesions, provide adequate assessment and help manage uterine lesions. It can improve the implantation rate, clinical pregnancy rate and sustained pregnancy rate of patients. It has also been shown that there is no significant difference in the rate of miscarriage, multiple births and ectopic pregnancies when compared to patients without hysteroscopic exploration. The disadvantages of hysteroscopy before embryo transfer are that the hysteroscopic procedure can cause damage to the cervix and postoperative manifestations such as lower abdominal discomfort can occur. Whether hysteroscopy is necessary before transfer, it is recommended to seek medical advice and consultation in a timely manner.
