Hysterosalpingogram (HSG)

A hysterosalpingogram (HSG) is a type of x-ray done with a contrast dye (iodine) so that clinicians can see whether the fallopian tubes are open and uterus (womb) has a normal shape.

The Procedure
During the HSG, you will be positioned under a fluoroscope, an x-ray machine that projects images onto a monitor. A speculum is used to open the vagina, and liquid is infused into the uterus through a tube called a cannula. The dye-containing liquid enters the uterus and the fallopian tubes, making it possible to see any abnormalities on the monitor. If the tubes are open, the liquid spills out into the abdominal cavity.

Recovery
HSG is an outpatient procedure that takes about half an hour. You may resume your normal activities immediately after an HSG, although in some cases your doctor may ask you not to have sexual intercourse for a few days. You may have some mild cramping during the HSG procedure or for several hours afterwards, and you may have spotting for a day or two after the procedure.

Risks
You may feel light-headed or faint after the procedure. A very few patients have an allergy to the iodine used as a contrast dye.

The radiation exposure is very low from an HSG but you should not undergo this procedure if you think you might be pregnant.

Call your doctor if you have a fever or severe pain.
