Hysterosalpingogram (HSG)

The HSG is a test in which a soft plastic catheter is inserted through the cervix up into the uterus and used to inject a colorless iodine-based dye into the uterus, while under a video-like x-ray system called fluoroscopy. The test is scheduled after the end of the menstrual cycle and prior to ovulation in order to avoid exposing a pregnancy to radiation or dye.

The images from the HSG tell us if the fallopian tubes are open and if there are fibroids, polyps or other abnormalities distorting the lining of the uterus. In some cases, the HSG itself may actually enhance your chances for pregnancy.

While the HSG is an important part of the infertility work up, it is not without risks. They include:

  • pain
  • infection (particularly if the tubes are blocked)
  • perforation
  • allergic reaction to the dye

 Although the HSG and SHG sound similar, they are somewhat different. Click here for information about the SHG.
