Ultrasound examination of the uterus and ovaries can not rule out tubal blockage, and in order to determine whether the tubes are blocked, tubal fluid or tubal imaging should be performed. Ultrasound of the uterus and ovaries can show the position and size of the uterus, the thickness of the uterine lining, the size of the ovaries, the development of follicles, and ovulation, but not whether the fallopian tubes are open or not. Tubal fluids and tubalography can be used to determine whether the tubes are blocked. 1. Tubal lubrication: under the supervision of ultrasound, saline is injected into the uterine cavity at the cervical area, and the resistance and reflux of the liquid during the injection are used to determine whether the tubes are open or not. 2. Tubalography: Under the X-ray to observe whether the fallopian tubes are open or not, and to be able to judge exactly which section is blocked. If there is no abnormality in the ultrasound examination of the uterus and ovaries and you want to know whether there is tubal blockage, it is recommended that you consult a doctor in time and have the relevant examination performed under the doctor’s advice.
