Résumé
Recent studies have shown that benzene extract of Ocimum sanctum [O. sanctum] leaves induces the ultrastructural changes in the epithelial cells of the cauda epididymis, its subsequent recovery in the seminiferous epithelium and fertility of male albino rats. Our aim was to investigate the effect of benzene extract of O.sanctum leaves on the cauda epididymal sperm parameters, morphology and their organelles at the ultrastructural level in albino rats. Wistar male rats [n=20] were allocated into two groups of control [n=10] and test group [n=10]. The test group received benzene extract of O.sanctum leaves [250mg/kg/day] for 48 consequence days. Five animals from each group were used for fertility test. Twenty-four hours after the last dose, the rest of the control [n=5] and treated [n=5] animals were sacrificed by cervical dislocation and then the cauda epididymal plasma was used for sperm analysis, scanning electron microscopy [SEM] and transmission electron microscopic [TEM] studies. Sperm analysis of test group exhibited significant [p
