OBJECTIVE: This study aimed to explore the potential protective effects of adipose-derived mesenchymal stem cell secretome (ASE) on oxidative stress triggered by Bisphenol-A (BisA) exposure in testicular mitochondria and sperm quality of rats.
METHODS: Testicular tissue mitochondria and sperms were exposed to BisA (8 μM) and ASE (50 or 100 μg). ∆Ψm (mitochondrial membrane potential), reactive oxygen species (ROS) levels, antioxidant biomarkers, and sperm parameters were measured.
RESULTS: BisA elevated biomarkers of oxidative stress in mitochondria, while the levels of antioxidant activity and ∆Ψm decreased significantly. BisA harmed the morphology, survival rate, and mobility of the spermatozoids. ASE lowered malondialdehyde contents and ROS generation in the mitochondria, increased ∆Ψm, and reversed sperm quality.
CONCLUSIONS: These data indicated that ASE effectively reduced BisA-induced damage to mitochondria and enhanced sperm quality by averting oxidative stress.
