To check whether the fallopian tubes are blocked or not, you can go through hysterosalpingography, ultrasonography of the fallopian tubes and special examination. 1. Hysterosalpingography: This is a common test method, which is performed 3~7 days after menstruation. During the test, the doctor will inject X-ray contrast into the uterus first, and then conduct X-ray examination, which can obviously find out whether there is any blockage. 2. Uterine tube ultrasonography: this test involves injecting a contrast agent into the uterine cavity under ultrasound monitoring, and then observing the passage of the contrast agent through the uterine tubes, which can determine the patency of the tubes. 3. Special examination: laparoscopy and tuboscopy can be used for examination, which can understand the mucous membrane inside the fallopian tube, and also can find adhesion or blockage. You can also use hysteroscopic tubal insertion and fluids, this test can confirm and exclude the proximal tubal obstruction suggested by hysterosalpingography, and treatment can also be given at the same time. If tubal blockage is diagnosed, early and standardized treatment is recommended to minimize the adverse effects of the disease.
