Hysterosalpingogram (HSG)

A hysterosalpingogram (HSG) is a x-ray test that uses dye to map the inside of the uterus and the fallopian tubes. This is the test used to check for blocked tubes, but it is also used for evaluation after recurrent miscarriage or IUD displacement.[1]

This test is performed 7-10 days after the beginning of your cycle. For the test, you will lie down on a table in an x-ray room underneath an x-ray imager (called a fluoroscope.) A technologist or radiologist will then insert a speculum (colloquially called a “duck”) into your vagina to keep it open. The cervix is then cleaned with an aseptic solution. A thin tube called a cannula is then inserted into the cervix and your uterus and tubes are filled with iodine. The speculum is removed and an x-ray is taken as the fluid moves through the reproductive organs. Once the pictures are finished, the tube is removed.[2]

The test can be painful if tubes are blocked as dye has no room to move down.

 

Additionally, cramping and bleeding is possible for a day after the test. For this reason, taking Tylenol is suggested an hour before the test. If not, after the test is also okay.

Results can be reviewed with a doctor immediately after the HSG, but sometimes it may take a day or two.
