Blockage of one or both oviducts with intraluminal gelatinous mases consisting of a mixture of collagen, fibroblast cells, and other debris, can result in reduction of fertility in the mare. Access to the oviduct for both diagnostic and therapeutic purposes is limited. As discussed in Chapters 27 and 28, both the diagnostic starch granule test and the fluorescent microspheres test have their limitations for the evaluation of oviductal patency in the mare and neither method treats a potentially blocked oviduct.

Flushing of the oviduct has been performed as both a diagnostic and a therapeutic procedure. Techniques have included retrograde flushing from the utero‐tubular junction (UTJ) proximally toward the infundibulum and normograde flushing from the infundibulum distally toward the uterus using either a standing flank laparoscopic or ventral midline laparotomy approach. In addition, retrograde flushing of the oviduct via the UTJ is possible using a standing hysteroscopic approach (see Chapter 32).

Oviductal flush techniques are reserved for mares that have a prolonged history of infertility, with good breeding management, bred to fertile stallion(s), and that have no other significant reproductive abnormalities noted during a breeding soundness evaluation.
