Rahimi-Feyli P., Case of triorchidism in a ram, Onl J Vet Res., 26 (12): 857-860, 2022. Triorchidism is a rare congenital disorder defined as the presence of more than two testes. We report a case of a 3-years-old Sanjabi Ram with three testes. Diagnosis was confirmed by microscopy. During necropsy sever bronchopneumonia was detected in lungs, three testes were found in carcass, two in left and one in right scrotums. a soft mass that is approximately the same size as left testis, and 1 vas deferens were noted in the left scrotum. The right testis and vas deferens scrotum were normal. Microscopically, the seminiferous tubular compartment in supernumerary testis appeared smaller than normal tubules. Spermatogonial cells, spermatocyte and sertoli cells were present in seminiferous tubules but mature spermatozoa were not seen.
