What is a hysterosalpingogram?

A hysterosalpingogram (HSG) is a specialized diagnostic X-ray Dr. Mohsin uses to look inside your uterus and fallopian tubes. It helps her diagnose and assess gynecological problems like blocked fallopian tubes that affect fertility.

The procedure requires a contrast medium (dye) injection into your uterus that shows up on an X-ray. The contrast outlines the uterus and fallopian tubes to make the images clearer.

HSG is minimally invasive, requiring no surgical incisions. It’s also very safe, although you should avoid one if you’re pregnant, have a pelvic infection, or suffer from heavy uterine bleeding.

How do I prepare for a hysterosalpingogram?

An HSG requires very little preparation. Dr. Mohsin might recommend taking pain medication an hour before your procedure to minimize discomfort, and some patients might need an antibiotic before their HSG.

Dr. Mohsin performs an HSG during days 1-14 of your menstrual cycle to reduce the chance you’re pregnant. You could also have a pregnancy test beforehand to be sure.

What does having a hysterosalpingogram involve?

You lie on your back for an HSG, just like having a pelvic exam. Dr. Mohsin inserts a speculum into your vagina to open the walls so she can see, clean, and anesthetize your cervix. You might feel a brief pinch during this process.

Dr. Mohsin grips your cervix with a special instrument and feeds a cannula (flexible pipe) through to the uterus. Or she might use a cannula fitted with a balloon to help keep the tube in position. Dr. Mohsin removes the speculum and puts you under an X-ray machine, gradually filling your uterus and fallopian tubes with a contrast medium.

She takes X-ray images as your uterus and fallopian tubes fill with contrast material, then removes the cannula. The X-ray shows the dye flowing freely if your fallopian tubes are open. If there’s a blockage in your fallopian tubes, the dye meets a barrier that stops its flow. Your body harmlessly absorbs any stray fluid.

What happens after my hysterosalpingogram?

You can go home after your HSG, but it’s best to have someone drive you as you might feel tired or uncomfortable.

After reviewing your HSG result, Dr. Mohsin discusses the findings and your options if you need further treatment.
