Tubal obstruction is mainly due to inflammation or other mechanical factors leading to tubal nowhere, which is the main cause of female infertility, accounting for about 30% of female infertility. The main causes of tubal obstruction are chronic pelvic inflammatory disease or surgery. The main reason is actually chronic pelvic inflammatory disease, which can mainly be manifested as lower abdominal pain, sexual pain or abnormal leucorrhea secretion and so on. In fact, tubal obstruction should be treated differently according to the different blocking sites, and the specific situation should be analyzed according to age and ovarian function. In general, young patients, if the ovarian function is good and the tubal blockage is not in the interstitial part, but in the ampulla or umbrella tip, we suggest that they do laparoscopic tubal plastic surgery and then actively try to get pregnant, about three months to six months. If they are not pregnant, we think that the adhesion may still be heavy and may recur. If it is in the uterine horn or isthmus, the effect of plastic surgery is not ideal, so we suggest that he directly consider IVF technology, or because the patient is older and the ovarian function is not good. So we choose IVF directly.
