During the test, a dye (contrast material, Opens dialog) is put through a thin tube. That tube is put through the vagina and into the uterus. Because the uterus and the fallopian tubes are connected, the dye will flow into the fallopian tubes. Pictures are taken using a steady beam of X-ray (fluoroscopy, Opens dialog) as the dye passes through the uterus and fallopian tubes. The pictures can show problems such as an injury or abnormal structure of the uterus or fallopian tubes. They can also show a blockage that would prevent an egg moving through a fallopian tube to the uterus. A blockage also could prevent sperm from moving into a fallopian tube and joining (fertilizing) an egg. The test also may find problems on the inside of the uterus that affect fertility.
A hysterosalpingogram (HSG) is done to:
Check for a blocked fallopian tube. The test may be done to look for the cause of infertility. An infection, endometriosis, Opens dialog, or a previous ectopic pregnancy, Opens dialog may cause severe scarring of the fallopian tubes and block the tubes. This can prevent pregnancy.
Schedule your test for when you won't be having your period. Your doctor may suggest that the test be done soon after your period ends and before your ovary releases an egg (ovulates). This timing allows your doctor to see the inside of your uterus better. It also avoids doing the test when you could be pregnant.
Tell your doctor about any allergies that you have and any medicines you take. Your doctor will tell you if you should stop taking any medicines before the procedure.
Your doctor may have you take an over-the-counter pain medicine, such as ibuprofen, about an hour before your test. This can help with cramps and pain during the test.
You may want to bring a sanitary pad to wear after the test. That's because some of the dye may leak from your vagina after the test. You may also have some slight bleeding.
Information about Hysterosalpingogram (HSG)
You'll be asked to take off your clothes below the waist and drape a gown around your waist.
You will need to empty your bladder.
You will lie on your back on an exam table with your feet and legs supported by footrests.
You may take ibuprofen to help with cramps or pain during the test. You may also get a sedative to help you relax.
The doctor may place a tool called a speculum into your vagina. It opens the vagina a little bit so your doctor can see inside.
A thin tube is put through the cervix into the uterus. A dye is put through the tube.
The X-ray pictures are shown on a video screen during the test.
How long the test takes
The test will take about 15 to 30 minutes.
After the test
You will probably be able to go home right away.
You can go back to your usual activities right away.
Some of the dye may leak out of your vagina.
You may have some vaginal bleeding for several days after the test.
You will most likely feel some cramping like menstrual cramps during the test. The amount of pain you have depends on what problems the doctor finds and treats during the test.
There is always a small chance of damage to cells or tissue from being exposed to any radiation. This can include the low levels of radiation used for this test. The chance of damage from the X-rays is generally very low compared with the possible benefits of the test.
There is a small chance of a pelvic infection after the test. Your doctor may give you antibiotics if they think you might get a pelvic infection.
There is a small chance of damaging or puncturing the uterus or fallopian tubes during the test.
There is a small chance of an allergic reaction to the iodine X-ray dye.
Hysterosalpingogram
Normal:
The shape of the uterus and fallopian tubes are normal. The fallopian tubes are not scarred or damaged. The dye flows freely from the uterus and through the fallopian tubes and then spills normally into the belly.
