Hysterosalpingography(HSG) is a test where a tube is inserted into the uterus, and from the tube a liquid(contrasting agent) is then injected. After observing on a monitor how it spreads and taking an X-ray, we can understand the following:
① Condition of the Fallopian tubes
② Conditions of inner uterine cavity, uterus shape
③ Whether or not there is adhesion in the Fallopian tubes
The Fallopian tubes are connected to the uterus, and where the sperm and oocyte meet to be fertilized. During this test and afterwards there might be pain similar to menstrual pains and possibly for several hours depending on the individual.
By taking this test we can get important information we can use for further treatment. There have been several cases of patients whose Fallopian tubes were in bad condition and just by taking this test the tubal problem was fixed and were able to get pregnant.
The test is usually done after menstrual bleeding has completely stopped, within 10 days from the start of the menstrual cycle, but it might be done at another time based on the doctor's judgement. You cannot engage in sexual activities until the test has been completed.
