Description Background: This study was conducted for to explore the plausible pathway of Chenopodium album seed extract (CAE)-mediated sperm
cell death.
Study Design: The role of CAE for its spermicidal action was assessed by (a) measuring lipid peroxidation, protein carbonyl content and
intracellular glutathione content in CAE exposed sperm cells; (b) assaying antioxidant enzymes like catalase and superoxide dismutase
(SOD); (c) analyzing protein expressions by using sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blot analysis; (d)
fluorimetric measurement of intracellular H2O2 level and generation of reactive oxygen species (ROS) in CAE-treated sperm cells; and (e)
DNA ladder formation study.
Results: CAE-induced sperm death is due to (a) lipid peroxidation of the sperm cell membrane, oxidation of some critical cellular proteins
and depletion of intracellular reduced gluthathione, indicating production of ROS; (b) activation of Mn-SOD and inactivation of catalase
favoring endogenous accumulation of H2O2; (c) generation of O2 U− at an enhanced rate during oxidative stress as evidenced by increased Mn-
SOD activity and protein expression; (d) accumulation of ROS in spermatozoa reflected in the fluorimetric experiments; and (e) increased
production of O2 U− and H2O2 induced apoptosis-like death in sperm cells as observed by DNA ladder formation.
Conclusion: The sperm death mediated by CAE is due to oxidative damage of cellular macromolecules by in situ generation of ROS.
