HSG (Hysterosalpingography): A Guide to This Essential Fertility Test

What is Hysterosalpingography (HSG)?

Hysterosalpingography (HSG) is a special X-ray test. Doctors use it to look at a woman’s uterus and fallopian tubes. Often, the HSG test helps find out why a woman may have trouble getting pregnant. During the HSG procedure, a dye is placed inside the uterus. Then, X-ray images show if the dye moves through the fallopian tubes. This test gives important information about the shape and health of these organs.

Why is HSG Performed?

Doctors recommend HSG for several reasons. Most often, it checks for blockages or problems in the uterus or fallopian tubes. For example, if a woman has trouble getting pregnant, the HSG test can help find the cause. Sometimes, it is used after certain surgeries or to check for repeated miscarriages. In addition, HSG can show if there are growths, scars, or other issues inside the uterus.

How to Prepare for an HSG

Proper preparation helps make the HSG procedure safe and smooth. Here are some HSG preparation tips:

  • Schedule the test after your period but before ovulation, usually days 7–10 of your cycle.
  • Tell your doctor if you are or might be pregnant.
  • Inform your doctor about any allergies, especially to iodine or contrast dye.
  • Take pain relief medicine, like ibuprofen, about an hour before the test if your doctor suggests it.
  • Arrange for someone to drive you home if you feel nervous or expect discomfort.

    • Above all, follow your doctor’s instructions closely for the best results.

    Step-by-Step HSG Procedure

    Knowing what happens during the HSG procedure can ease worries. Here is a step-by-step guide:

  • You will lie on an exam table, much like during a pelvic exam.
  • The doctor will place a speculum in your vagina to see the cervix.
  • A thin tube is gently inserted into the cervix.
  • Next, a special dye is slowly injected through the tube into the uterus.
  • X-ray images are taken as the dye moves through the uterus and fallopian tubes.
  • After the images are complete, the doctor removes the tube and speculum.

    • The whole HSG test usually takes less than 30 minutes.

    What to Expect During and After HSG

    During the HSG test, you may feel mild cramping or pressure. Some women feel a bit of discomfort when the dye is injected. However, this feeling usually lasts only a few minutes. After the procedure, you might have light spotting or mild cramps for a day or two. Most women can return to normal activities the same day. If you feel dizzy or have heavy bleeding, call your doctor right away.

    Possible Risks and Side Effects

    HSG is a safe procedure for most women. Still, like any test, there are some possible risks and side effects. These may include:

  • Mild pain or cramping during or after the test
  • Light vaginal bleeding or spotting
  • Allergic reaction to the dye (rare)
  • Infection (rare)

    • Although serious problems are rare, always tell your doctor if you have fever, severe pain, or heavy bleeding after the HSG procedure.

    Interpreting HSG Results

    After the HSG test, a radiologist looks at the X-ray images. The results show if the uterus and fallopian tubes are normal or if there are blockages or other problems. If the dye flows freely, it means the tubes are open. If not, there may be a blockage. Your doctor will explain the HSG results and what they mean for your health and fertility. Sometimes, more tests may be needed for a full diagnosis.
