Abstract
Abstract: Three healthy adult local breed rams were subjected to partial caput epididymectomy to evaluate histopathological changes. The skin in caudal aspect of scrotal raphe pouch was transected longitudinally. The first testis was forced toward the other, the tunica vaginalis was incised at the upper of the epididymis body and a piece of one cm in length was removed from it with ligation. The same procedure was repeated for the other testis. Time of sexual desire was significantly longer (p<0.05) after one and two weeks of the operation than three and four weeks for control, while it was longest after one weeks among all other periods. Sperm concentration was significantly lower (p<0.05) after 2, 3 and 4 weeks than the first week for control, while it was significantly lower after first week than control. The histopathological changes in testicular tissue were evaluated after one, three and six months of the operation. The results revealed thickening of the basement membrane of seminiferous tubules and degeneration, necrosis of spermatogonia and sertoli cells. Some seminiferous tubules appeared only with covering basement membrane. The Leydig cells were proliferated at the first period, while there was decrease in their number at the last period.
