In Office HSG
A hysterosalpingogram (HSG) is a procedure to evaluate tubal patency for couples who are having difficulty conceiving. Historically, this procedure was performed in a hospital radiology department using dye. However, there is now an option to have this performed in the office setting with ultrasound evaluation.
During this procedure, the physician injects a mixture of saline and air into the uterus, and through ultrasound evaluation determines if the mixture moves through the fallopian tubes appropriately. This will determine if the fallopian tubes are opened or blocked.
