This study was aimed to declare the role of epidydimal passage on semen features, DNA integrity and ultrastructure's changes in dromedary camel. The testes with attached epididymis of mature dromedary camels (n=50) were collected during the rutting season from December to April. The harvested spermatozoa from the three-main anatomical epidydimal segments (Head, body and tail) were assessed for semen characters, DNA integrity as well as,
ultra-structural changes. A significant difference in semen features (individual motility, sperm count, membrane and acrosome intactness, viability, normality, maturity, abnormalities and acrosome length and perimeter) among different epidydimal segments. Spermatozoa from epidydimal tail showed a significantly (p
