The aim of this study is to evaluate the beneficial effect of Myoinositol (MYO) supplement in freezing media on the post thaw sperm quality. Semen samples from 40 normozoospermic men were divided into two aliquots and frozen with simple or 2 mg/mL MYO supplemented freezing medium. Post thaw process including, computer-assissted sperm analysis was used to analyze sperm motility and morphology. Reactive oxygen species was evaluated by the fluorometry of DCFH-DA, as well as total antioxidant capacity and lipid peroxidation were measured based on colorimetric assay by ELISA reader. Eventually, DNA fragmentation was assessed using TUNEL staining. MYO significantly improved progressive motility and normal morphology in treated samples (p < 0.05). Lipid peroxidation (malondialdehyde level) can be diminished in samples were frozen by MYO supplemented freezing media (p < 0.05). While MYO did not affect the amount of ROS (p > 0.05), it was associated with high values of total antioxidant capacity (p < 0.05). DNA integrity was significantly affected by MYO, as in MYO treated samples, DNA fragmentation was decreased compared to control ones (p < 0.001). The findings support the use of 2 mg/mL myoinositol supplemented freezing media in sperm cryopreservation to increase sperm quality after freezing–thawing procedures.
