Hysterosalpingogram (HSG)


This diagnostic procedure is a fluoroscopic x-ray exam used to identify problems in the uterus and fallopian tubes that may be causing infertility or to confirm that the tubes are completely blocked after a hysteroscopic tubal occlusion procedure. This outpatient procedure takes about 15-20 minutes to perform.


In preparation for the procedure, the patient is positioned on a fluoroscopic exam table and a speculum is inserted into the vagina to allow access to the cervix. In some cases a local anesthesia may be administered, but typically no anesthesia is needed.

Inserting the Catheter

The physician inserts a thin catheter through the opening of the cervix and carefully advances it into the uterus. In some cases, the cervix may be grasped and stabilized with a specialized pair of forceps while the catheter is inserted.

Administering the Dye

The physician infuses the uterus with a contrast dye. The dye fills the uterus and should begin to flow into the fallopian tubes. The physician watches the progress of the dye on the fluoroscope monitor, and can identify any blockages in the tubes. Tubes that are not blocked will allow the dye to travel all the way through and flow into the abdominal cavity. X-ray images are taken from the patient’s front and side.

End of Procedure and Aftercare

When the procedure is finished, the instruments are removed and the patient is allowed to go home and resume normal activities. No special aftercare is required.
