The professional name of IVF is in vitro fertilization-embryo transfer, which, as the name suggests, is simply a method of fertilizing a female egg and a male sperm in vitro to form a fertilized egg (embryo), and then implanting the embryo into the woman’s uterus to assist in conception. Before IVF, both men and women need to undergo a series of preoperative tests, such as routine blood and urine tests, liver and kidney tests, and electrocardiograms, in order to determine whether both parties have other systemic diseases, so what is the hysteroscopy test and what is its purpose? As I mentioned at the beginning of the article, IVF is ultimately about implanting embryos into the woman’s uterus, so the environment of the uterus is one of the key factors that affects the pregnancy rate, and if there are abnormalities in the uterus, the pregnancy rate will definitely be affected. Among the various tests available, hysteroscopy is what we believe to be the best method for exploring the uterine environment. It is intuitive, comprehensive, accurate and can be used for therapeutic purposes at the same time. The hysteroscopy is performed through the vagina and cervical canal into the hysteroscope, where the inside of the uterus is visually inspected through a tiny viewing mirror to identify problems and resolve them. It is through this examination that some IVF patients have been able to have their endometrial polyps scraped, uterine adhesions, longitudinal uterus found, and even endometrial tuberculosis detected in time before treatment, thus removing a stumbling block in the IVF process and removing an obstacle to lowering pregnancy rates.
