Hysterosalpingogram (HSG) Instructions

The Procedure

Your physician has advised you to schedule a hysterosalpingogram or HSG. This procedure is performed to determine the patency of your tubes and to evaluate the interior contour of your uterus. This information is obtained by an x-ray study using contrast material (dye) that appears white on x-ray.

This test is performed after your menstrual period but before anticipated ovulation (cycle day #7-11). This test will be done by your physician in the radiology department of the hospital. An instrument will be placed into the cervix, through the vagina. X-ray pictures are taken as the dye passes through the uterus and out the ends of the tubes. It is a short procedure that usually takes 10 to 15 minutes.

Pelvic infection is a risk, which occurs in 1% of all patients. To minimize the risk we have our patients use an antibiotic. If you have had a previous history of pelvic inflammatory disease (PID) or infection of the uterus, tubes or ovaries, you should notify the physician and the nurses.

During the procedure, you may experience some mild cramping. Cramping along with light bleeding for a day or so after the procedure is not abnormal. You may take Tylenol or Advil one hour prior to the test to minimize cramping. Contact your physician if you develop a fever of 100 F or greater, have severe abdominal pain or very heavy bleeding after the procedure.

To Schedule Your Procedure

Call the office no later than the third day of your menses to schedule between cycle days 7-11. Have the following information available:

  • Starting date of this menstrual cycle
  • Is this a normal or abnormal menstrual cycle? (Is your period lighter or heavier, early or late)?
  • Do you have any drug allergies?
  • Are you allergic to iodine or shellfish?
  • Have you ever had a previous reaction to any x-ray dye?
  • Have you ever had any previous tubal or uterine infections?
  • Pharmacy name and number to order antibiotics


The Day Before Your HSG:

Start your antibiotic (Z-pack). Take two pills the day before your test and one pill per day for the next 4 days. Finish the entire antibiotic.

On the Day of Your HSG:

Arrive at the hospital and report to the office first. You will need to provide a urine sample.

Check in with outpatient registration, which is located on the ground floor next to the emergency room entrance.

Make certain to bring any appropriate insurance forms or referrals.
