The oviduct plays a critical role during fertilization and early embryonic development. This chapter describes the starch granule test for the diagnosis of oviductal patency. The starch granule test involves the deposition of a starch suspension onto the ovarian surface and the subsequent recovery of starch from the uterus or cervix. One oviduct can be tested at a time. The chapter discusses step by step procedure for the diagnosis of oviductal patency in mare, and lists the equipment and supplies needed. The starch granule test requires individual testing of each oviduct on separate estrous cycles.
