Correlation between mitochondrial dysfunction of spermatozoa and their biological adequacy

One of the most significant indicators affecting male fertility is sperm nuclear and mitochondrial DNA fragmentation index (DFI). damage depends on biotic abiotic factors, leading to oxidative stress (O.S.). This research aimed investigate relationship between dysfunction spermatozoa their biological adequacy. The material was frozen-thawed samples from Ayrshire, Russian Black Pied Holstein, Red Limousin, Polled breeding bulls. Assessments mobility, morphology, were performed using computer-assisted analysis (CASA). It found that there a negative correlation activity with coefficient r = -0.24. incidence abnormal correlated 0.77. nDNA in chromatin varied 0 25%.
