Fimbrial Cyst.
A large fimbrial cyst on the right. These cysts may block the oviduct and prevent the sperm from reaching the ovum / ova. If the blockage is unilateral, the ewe is still capable of conceiving on the contralateral side.

Mesonephric Duct Cyst.
Remnant of the male duct system (Wolffian duct). These cysts are capable of occluding the oviduct. Not so in this case as the oviduct is not distended with fluid. This cyst may create confusion in an ultrasonogram.

Parovarian Cyst.
A bi-lobed parovarian cyst is present in the left mesovarian. These cysts are mesonephric in origin. The left oviduct is distended with fluid due to an obstruction. In this case segmental aplasia of the oviduct is likely, in view of the presence of a bi-lobed mesonephric duct cyst suggesting multiple developmental anomalies.
