Hysterosalpinogram

A hysterosalpinogram (HSG) is a fluoroscopy exam that is used to evaluate the shape of your uterus cavity and fallopian tubes.

The tool is helpful in the diagnosis of abnormalities in your uterus and conditions such as Asherman's syndrome and blocked fallopian tubes. The study is also done for women who are having a difficult time getting pregnant. Studies show that pregnancy rates increase in a cycle when an HSG has been performed.

What should I expect?

The exam is usually performed between day seven and day 10 of your menstrual cycle.

During the test, a contrast material is injected into the uterine cavity through the vagina and cervix. If the fallopian tubes are open, the contrast material will fill the tubes and enter the abdominal cavity. X-ray pictures are taken with a fluoroscope as the material passes through your body.

The exam takes about 30 minutes.
