Abstract

A ewe with apparently normal estrous cycles was unable to conceive as a result of a single ovotestis. The ovotestis was diagnosed on the basis of results from laparoscopic examination, human chorionic gonadotropin stimulation, and histologic examination of the gonad. The report reinforces the necessity of considering all causes of infertility in affected sheep, and not simply infective causes.
