A mouflon showing severe weight loss and cachexia was examined. The animal had horns and a male-like body frame but the preputial fur was missing. The scrotum was completely absent. Both testicles were located next to the inguinal canal under the skin, and appeared only slightly smaller than normal. The prepuce was located in a perianal position under the anus and it resembled a vulva. The penis was underdeveloped and curled up inside the prepuce like an enlarged clitoris. The bulbourethral region and the urinary bladder looked normal. The orifice of the urethra was located in its normal position, but the glans penis appeared deformed. Microscopic examination of the testicles revealed mild degeneration of the seminiferous tubules and a marked proliferation of the interstitial connective tissue with Leydig cells still present. There were no marked changes in the bulbar part of the penis but the apical part exhibited marked interstitial fibrosis. This is the first description of hypospadias and cryptorchidism in mouflon.
