Hysterosalpingogram (HSG)

The HSG is an outpatient procedure performed at the hospital radiology department. Radiopaque die is injected into the uterus using a catheter. Sequential X-rays are taken as the dye flows from the uterus back through the fallopian tubes. If there is a constriction, or blockage of the fallopian tubes, it shows on the x-ray as a collection of die where its flow was impeded. Uterine structural abnormalities can also be identified.

Hysteroscopy

The hysteroscopy provides direct visualization of the uterine cavity by filling the uterus with gas and directly examining it via the hysteroscope. The hysteroscope is "like a telescope" and allows the fertility specialist to identify abnormalities such as polyps, fibroids, adhesions and other abnormalities. The reproductive surgeon can often treat these conditions during the hysteroscopy avoiding the need for a repeat procedure.

Hydrosonogram

The hydrosonogram is useful in identifying polyps, fibroids, and other uterine abnormalities. Saline solution is injected into the uterus causing it to expand and the ultrasound vaginal probe is inserted. The saline solution increases the contrast making abnormalities more evident.
