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 500,000 procedures worldwide. With proper imaging techniques, it has the ability to achieve accuracy equal to that of an HSG, making it a great 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.
