Hysterosalpingography is the most common clinical tool to check the patency of the fallopian tubes, and most women with infertility undergo this test, which can be done on an outpatient basis without anesthesia. In simple terms, a catheter is inserted through the patient’s vagina into the cervical opening and contrast is slowly injected into the uterine cavity. With the assistance of radiology, the uterine cavity is dynamically observed using X-ray fluoroscopy, and the patency of the contrast through both fallopian tubes is recorded on film. During the examination, you may feel discomfort such as soreness and swelling, but it is usually not painful. However, if there is a mild blockage that needs to be unblocked, there will be some pain, but it is within the tolerable range and of course it varies from person to person. It is recommended to fully communicate with the doctor before the operation, to understand the approximate steps and procedures of the examination, to be psychologically prepared, to dispel concerns, and to cooperate with the doctor during the examination, the more emotional tension and fear, the more the muscles cannot relax, but will be more painful. Tubal factors causing infertility account for about 1/3 of infertility. Hysterosalpingography is the preferred method to diagnose tubal patency, and through this test, many causes of infertility can also be found, and it also has a certain therapeutic effect, and some patients can get pregnant naturally soon after the operation. So, be sure to relax and take the test.
