Hysterosalpingography (HSG): What to Expect, Procedure, and Safety

Introduction

Hysterosalpingography (HSG) is a special X-ray test. Doctors use it to look at a woman’s uterus and fallopian tubes. Often, this test helps find the cause of infertility or repeated miscarriages. During HSG, a doctor uses a dye to make the inside of the uterus and tubes visible on X-ray images. Because it gives clear pictures, HSG helps doctors plan the best treatment. According to the CDC, HSG is a common and safe way to check for blockages or problems in the uterus and tubes.

When is HSG Recommended?

Doctors may suggest Hysterosalpingography (HSG) for several reasons. Usually, it is recommended when:

You have trouble getting pregnant and need an infertility workup.

You have had more than one miscarriage.

Your doctor suspects a blockage or shape problem in your uterus or fallopian tubes.

You have unusual bleeding or pain that needs further study.

Because HSG gives detailed images, it helps doctors find the exact cause of these problems.

How to Prepare for HSG

Proper preparation can make your Hysterosalpingography procedure smoother. Here are some helpful HSG preparation tips:

Schedule the test for 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 any prescribed pain medicine about 30-60 minutes before the test.

Arrange for someone to drive you home if you feel uncomfortable after the test.

Follow any other instructions your doctor gives you, such as fasting or avoiding certain medicines.

Because preparation helps reduce stress, always ask your doctor if you have questions.

Step-by-Step Overview of the HSG Procedure

Knowing what to expect during HSG can ease your worries. Here is a simple step-by-step guide:

You will lie on an exam table, much like during a pelvic exam.

The doctor places a speculum in your vagina to see your cervix.

Next, the cervix is cleaned, and a thin tube is gently inserted.

Through this tube, the doctor slowly injects a special dye.

As the dye fills your uterus and tubes, X-ray pictures are taken.

The doctor watches the dye move to check for blockages or shape problems.

After the images are complete, the doctor removes the tube and speculum.

Because the test usually takes less than 30 minutes, you can go home the same day.

What to Expect During and After HSG

During the HSG test, you may feel mild discomfort or cramping. Some women say it feels like period cramps. However, the pain usually lasts only a few minutes. After the test, you might notice:

Light spotting or discharge for a day or two

Mild cramping for a short time

A small amount of dye coming out of your vagina

Because these symptoms are common, they should go away soon. If you have heavy bleeding, fever, or severe pain, call your doctor right away.

Safety, Risks, and Side Effects

HSG test safety is well established. Most women have no serious problems. Still, like any medical test, there are some risks. Possible side effects include:

Mild pain or cramping during the test

Light vaginal bleeding

Allergic reaction to the dye (rare)

Infection (rare, but possible)

Injury to the uterus or tubes (very rare)

Because the amount of X-ray radiation is very low, it is considered safe for most women. The World Health Organization notes that HSG is a safe and useful test when done by trained professionals.
