| Popis: | The aim of this study is to evaluate the beneficial effects of N-acetyl-cysteine (NAC), alpha lipoic acid (ALA) and combination of NAC + ALA supplement in freezing medium on Sperm structural and functional in asthenoteratozoospermia patients. Thirty freshly ejaculated semen samples were cryopreserved with sperm freezing medium (SFM) as control group and three group that SFM supplemented with NAC, ALA and their combination NAC+ ALA. The sperm samples were analysed according to WHO. Mitochondrial membrane potential (MMP), acrosome reaction (AR), antioxidant enzymes and DNA fragmentation were assessed using by Rhodamine123, PSA- FITC ELISA and TUNEL staining respectively. Expression level of NRF2 was assessed by real-time PCR assay. NAC and ALA alone significantly improved sperm motility, viability and DNA fragmentation (p 0.05). MMP increased in NAC and ALA separately (p 0.05). While did not affect the amount of sperm morphology and AR (p 0.05). Antioxidant enzymes significantly difference in NAC and ALA groups (p 0.05). In addition, NAC and ALA groups showed a significantly higher expression of NRF2 gene compared with other groups (p 0.05). Our results revealed that the ALA and NAC supplements had a protective effect in cryopreservation process on the structural and functional characteristics of sperm. |
