Hysterosalpingogram (HSG)

An HSG (hysterosalpingogram) is an X-ray exam in which we inject contrast dye into your uterus through a thin, flexible tube called a catheter that we place in your vagina. Your doctor may order this exam if you are experiencing infertility. An HSG lets us examine the anatomical structure and condition of your uterus and whether your fallopian tubes are blocked. The test also helps us detect various abnormalities that may be in your uterus, such as:

• Adhesions, buildups of scar tissue that causes the uterine walls to bind together
• Fibroids, noncancerous lumps that can grow on the uterus
• Polyps, growths in the uterine lining that can be noncancerous, precancerous, or cancerous

How Do I Prepare for the Exam?

You should have a pregnancy test before you have an HSG. Also, you must not have unprotected sex from the point at which your cycle begins until after your HSG is complete.

What Will Happen During the Exam?

You will undress and change into a hospital gown before lying on your back on a special X-ray table. A radiographer and an OB/GYN may be in the room for your exam. We will insert a tool called a speculum to open your vaginal walls, and we will apply an antiseptic solution to your cervix.

Next, we will insert a catheter into your uterus and remove the speculum. We will inject contrast dye through the catheter into your uterus. As the uterus fills, the dye should flow into your fallopian tubes. If this doesn’t happen, we may need to inject additional contrast dye, and you may need to roll to one side and then the other to ensure the dye flows where it needs to. We may apply pressure to ensure the dye flows as it should.

At various points during your HSG, we’ll take X-ray images. You may experience cramping and increased pressure during the test, but these feelings should improve after we remove the catheter and complete your exam. If you experience any of the following symptoms after your exam is complete, contact your doctor right away:

• Fever
• Heavy bleeding
• Increased pain

How Long Will the Procedure Take?

The actual HSG procedure usually only takes five to 10 minutes to complete. However, your appointment will last about 30 minutes. This allows us to consult with you before the procedure and set up the room, as well as to help you recover from the exam once it’s complete.

How Will I Receive My Results?

You will get the results of the exam from your referring doctor.
