Hysterosalpingogram, HSG

Hysterosalpingogram (HSG) or radiologic examination for the causes of infertility

The tests most commonly recommended as part of the female infertility workup are the Hysterosalpingogram (HSG) and Saline Infusion Sonogram (SIS).

Hysterosalpingogram (HSG)

A Hysterosalpingogram (HSG) is an X-ray study of the uterine cavity and fallopian tubes. It is used to determine if the shape of the uterine cavity is normal and if the fallopian tubes are open, or if they show signs of adhesions or blockages, which could inhibit or prevent the fertilization of the egg and movement of the embryo into the uterus. The HSG is a necessary step in determining the cause of infertility.

Scheduling an HSG

The HSG is scheduled between cycle days 5-11 of your menstrual cycle. Please call our office with the onset of your menses to schedule the HSG. You may wish to check with your insurance company regarding coverage for this procedure. You will need the following CPT codes to talk with your insurance company: 74740 and 58340.

The HSG Procedure

For the HSG, you will be in the same position as in a pelvic exam. The Physician will insert a cannula into the cervix, and then will inject the contrast fluid into the uterus. When the uterus begins to fill, the contrast fluid will follow its path, through the fallopian tubes, and out the ends of the fallopian tubes. The contrast fluid ends up in the abdominal cavity, where is it absorbed and disappears in time. The contrast agent in the contrast fluid shows up on X-rays that may be viewed from different angles.

Expected Results from an HSG

Your Physician will go over your results with you at the time of the HSG. If the fluid spills freely from the tubes, this indicates that your fallopian tubes are open. If the fluid does not flow through the tubes easily, then there could be a blockage of some kind, which can be caused by infections or scarring.

HSG Side Effects

There may be cramping as the Physician performs the HSG. You may take a cramp medication of your choice 30 to 45 minutes before the test. Some side effects which may occur are: severe cramping, nausea, dizziness, bleeding, and the possibility of infection after the procedure. For precautionary measures, it would be best to have someone drive you home, and you may want to stay off your feet for approximately two hours.
