Tubal Patency Evaluation

Hysterosalpingo-Foam-Sonography (HyFoSy)

While difficulty becoming pregnant can be common, it could be due to a blockage of the fallopian tubes. Hysterosalpingo-Foam-Sonography (HyFoSy) is a safe, accurate, and convenient way to determine whether your fallopian tubes are open or blocked. ExEm® Foam is an innovative FDA-approved contrast agent that has been successfully used in over 1 million procedures worldwide. With proper imaging technique, HyFoSy has the ability to achieve accuracy greater to that of an HSG1,* making it a better alternative for tubal patency assessment and diagnosis in women with known or suspected infertility.

How it works is simple, if the fallopian tubes are open, the foam will appear as a thin, bright white line on ultrasound. HyFoSy is less invasive and provides more information at a lower cost.
