title: Identification of anatomic features of the equine clitoris as potential growth sites for Taylorella equigenitalis.
abstract: A median clitoral sinus, as a space canalized from epithelial cells, was distinguishable developmentally in equine fetuses from 33-mm crown-rump length (CRL) to 500-mm CRL (including a mule of 21-mm CRL). In saggital sections of the clitoris of a 480-mm CRL fetus, indentations under the transverse frenular fold were identified as lateral sinuses of the clitoris. Unlike the median sinus, they were shallow; it therefore could not be anatomically substantiated that the lateral sinuses were of sufficient depth to support the growth of the partial anaerobe Taylorella equigenitalis, the organism of contagious equine metritis. This study indicated excision of the lateral clitoral sinuses was unnecessary for treatment of contagious equine metritis.
