Among the female infertility tests that are performed, HSG is an important test. Hysterosalpingography or HSG is a radiology test done to check the blockage of fallopian tubes. This test enables to understand the internal structure of uterus and fallopian tubes.
In order to get pregnant, there should be no blockage in fallopian tubes encouraging the egg to enter the uterus. If there is any blockage in tubes or if something is wrong with the uterus, then there will be a problem to conceive. This test is done to find out the health of fallopian tubes and uterus in a detailed way.
This radiology test can be done in a hospital or a healthcare provider’s clinic by an expert radiologist which is done during the first half (1-14 days) of the menstrual cycle.
A thin tube is threaded through the vagina and cervix where a contrast material that contains a dye is injected into the uterus. This dye moves through the body structures and outlines the inner size and shape of the uterus and fallopian tubes, which can be seen on an X-ray screen.
If there is a blockage, the dye cannot spread further and flows back into the uterus. But if the tube is open, the dye fills into the pelvic cavity where it resorbs.
If a woman is pregnant or if she has some pelvic infection, this HSG test should not be done. Once if this test is started and the lady starts bleeding, performing this test has to be stopped immediately.
Though local anesthesia is given during the procedure, the patient might experience some abdominal pain, bleeding, and cramps associated with some dizziness after the procedure.
