Definition of Hysterosalpingogram

A hysterosalpingogram, or HSG, is an outpatient X-ray procedure that uses an iodine contrast to outline the fallopian tubes and uterus. It takes 30 minutes to perform.

Uses

• A hysterosalpingogram is performed to assess the uterus for abnormalities, to evaluate the fallopian tubes for unusual blockages, to ensure the fallopian tubes are blocked after a permanent sterilization procedure and to diagnose fertility problems.

The Procedure

• You will lie on a table with your feet in stirrups. After a speculum is placed in your vagina, a thin tube will be inserted into the cervix. X-rays are taken through an overhead X-ray machine as iodine contrast fills your uterus through the thin tube.

Side Effects

• A hysterosalpingogram may cause uterine cramping for five minutes to several hours and spotting for one to two days. The uterine cramping can range from mild to moderate.

Risks

• According to the American Society for Reproductive Medicine, risks associated with a hysterosalpingogram are uncommon. These risks include a pelvic infection, fainting, a low level of radiation exposure and an allergic reaction to the iodine contrast.

Considerations

• You physician may suggest abstaining from intercourse for a few days after a hysterosalpingogram, but generally you can resume normal activities right away.

Normal Results

• According to the National Institutes of Health, a normal hysterosalpingogram reveals no defects in the uterus or fallopian tubes.
