Hysterosalpingogram…. a word that often strikes fear into the heart of fertility patients! This is a crucial part of the basic female fertility work up that examines the uterine cavity (i.e. the inside of the uterus where a pregnancy would implant and grow) and the Fallopian tubes, which should help transport an egg from the ovary to meet the sperm.

Does an HSG hurt?

⠀⠀⠀⠀⠀⠀⠀⠀⠀
Although an HSG is uncomfortable, most women tolerate it well. A small catheter is inserted during a speculum exam through the cervix, and a contrast medium such as dye or saline is introduced. The distention of the uterus and tubes causes cramping discomfort. We recommend taking ibuprofen prior to your HSG to minimize discomfort.

How is an HSG done?

An HSG can also be done in the fertility or gyn office using saline (water). A pelvic US is done to examine the contour of the cavity when it fills with saline, and 3D images can be obtained for an even better view! “Agitation” of the saline in the syringe can then be used to create air bubbles, which should pass through open tubes, creating a bright flash on ultrasound.

Recent studies suggest that HSGs with oil-based contrast lead to a higher clinical pregnancy and live birth rate in the following 6 months compared to no intervention. There is insufficient evidence to know if the same is true of water-based contrast medium.

What might be diagnosed with HSG?

An HSG can show us if there are blocked Fallopian tubes, as well as polyps, fibroids, or scar tissue in the uterine cavity could be identified. However, tubal “spasm,” or false positives, can occur.
