Abstract
In this study, the influence of myoinositol (MYO) as an antioxidant on the inhibition of the negative impacts of cryopreservation on sperm quality in men with Asthenospermia was investigated. In this prospective study, each semen sample from 25 cases was separated into three groups: Fresh, Control (with freezing medium), Myoinositol (2 mg/ml). According to the World Health Organization criteria (WHO) (2010), total motility, progressive sperm motility, viability, normal morphology, and DNA integrity were assessed. In addition, the hypo-osmotic swelling (HOS) test and mitochondrial membrane potential (MMP) were used. Total antioxidant capacity (TAC), malondialdehyde (MDA), and antioxidant enzyme activity were determined by the ELISA method. In contrast to the fresh samples, lipid peroxidation, DNA integrity damage, DNA fragmentation, HOST, and MMP had significant enhancement in the control samples. Sperm quality was significantly decreased (p < 0.05). Mean percentage viability, normal morphology, total motility, progressive motility, and DNA integrity were significantly enhanced in the MYO group in comparison to the control group (p < 0.05). The MDA and TAC levels and DNA damage in the MYO group were significantly lower compared to the control group (p < 0.05). The findings confirm that sperm quality in patients with Asthenospermia is improved by the administration of 2mg/ml of myoinositol together with the freezing medium after sperm cryopreservation.
