The purpose of hysteroscopy is to observe whether the uterine cavity is normal and whether there is any damage or adhesion in the endometrium, and also to determine whether there are any abnormal growths such as polyps and submucosal fibroids in the uterine cavity. Because IVF transplantation involves transplanting fertilized eggs into the patient’s uterine cavity, the chances of IVF transplantation failure are very high if the patient has abnormal endometrium or endometrial lesions. The cost of IVF is relatively high, and patients need to take a lot of medication to regulate their hormone levels and to maintain the development of the embryos after the transfer, so they are under great financial and mental stress. In order to increase the chances of success of IVF transfer, patients must have a hysteroscopy before doing the transfer and also need to do other examinations of the whole body, which can be regulated according to the situation in order to maximize the success rate of IVF.
