HyFoSy vs HSG: Fallopian Tube Test in Marin Fertility Center

We are excited to offer HyFoSy (Hi-Foh-Sigh), a novel ultrasound-based tubal patency test of the fallopian tubes. It is performed in our Marin office and, in contrast to traditional tubal testing (a hysterosalpingogram, or HSG), avoids any radiation.
