A hysterosalpingogram test is used to examine a woman’s uterus and fallopian tubes.
What is a Hysterosalpingogram Test?
A hysterosalpingogram test is an x-ray procedure in which a dye fluid is injected through the vaginal opening of the uterus called the cervix into the uterus and fallopian tubes. This “dye” appears white on the x-ray and allows the radiologist and your doctor to see if there are any abnormalities, such as an unusually shaped uterus, tumors, scar tissue or blockages in the fallopian tubes.
Timing for the Test
If you are trying to get pregnant in the same cycle as an HSG, make sure to schedule the test prior to ovulation so that there is no danger of “flushing out” a released egg or developing embryo.
Possible Side Effects and Risks
- Most women report only minor cramping, vaginal bleeding and short-term discomfort during this procedure.
- Some women experience severe cramping. In patients with severe discomfort, the fallopian tubes may be blocked. This occurs because the dye is unable to escape into the pelvic cavity. Instead, the dye fills and distends the tubes.
- Rarely, allergic reactions can occur, and some reactions can be serious. An allergy to iodine is a reason to not have this test.
Preparing for the Hysterosalpingogram Test
- We advise taking a pain relief medication about 30 minutes prior to the actual procedure.
- If there is a past history of pelvic infection, an antibiotic will be prescribed to prevent infection. You will be instructed to start the antibiotics one day prior to the procedure for three consecutive days duration.
What Can it Find?
- A hysterosalpingogram can identify structural abnormalities in the inner lining of the uterus called the endometrium, uterine wall and fallopian tubes.
- Fibroid tumors that grow into the uterine cavity
- Abnormal formation of uterus from birth (congenital) or previous surgery.
- Fallopian tube blockage
