What is the test?
The hysterosalpingogram is an x-ray test that takes a picture after dye has filled the inside of the uterus and fallopian tubes. It is a test that can help determine the cause of infertility. It is sometimes used to evaluate patients who have had several miscarriages. It can also be used to locate an IUD (intrauterine device) that cannot be seen on a pelvic examination. This test can show areas of scarring inside a fallopian tube or changes in the uterine cavity, as might occur with a polyp or other growth in the uterus.
How do I prepare for the test?
Tell your doctor if you have ever had an allergic reaction to x-ray dye or if you have had a recent infection in the pelvis. Definitely tell your doctor if there is a chance you might be pregnant. If you have regular periods, it is best to have this test done in the week right after your period ends. This is before ovulation occurs in your cycle, so there would be the least risk of exposing an early pregnancy to the dye used in this test. Some doctors will require you to have tests for pelvic infections before having a hysterosalpingogram.
