Abstract:
Background: The selection of sperm with good genomic in-tegrity and surface antigens is a critical factor in the success of assisted reproductive technology (ART) especially in male fac-tor infertility. This study assessed the potential DJ-1 and serum amyloid P compound (SAP) two sperm surface pro teomes as bio markers for sperm selection.Materials and Methods: Sperm were obtained from 114 men (72 asthenoteratozoospermic (AT) and 42 normospermic(N) who presented at Avicenna Fertility Clinic for their treatment. The semen characteristic, DNA fragmentation (DFI), chromatin maturation index ( CMI ), bio marker levels on sperm, and their correlation with embryo quality were assessed in both groups. The paired samples t-test and independent-samples t-test were used for analyzing the data and P values<0.05 were considered significant.Results: Outcomes exhibited the major reduction in DJ-1 and SAP following reduction in sperm quality and DNA integrity (P<0.001) with cut-off value of 12% (DJ-1) and 10% (SAP). The specificity of these three biomarkers was 73.8 and 88.1%, respectively. Also, DFI (P<0.001), CMI (P<0.05), cleavage (P<0.05), and embryos quality (P<0.001) decreased signifi-cantly in AT group in compared with NS group. It was shown that DFI was 76.5% in DJ-1 and 94.1% in SAP, and CMI was 75.50% and 87.5%, respectively. The significant correlation was found between of the two bio markers and CMI (P<0.001), DFI (P<0.001) and embryos quality (P<0.001).Conclusion: By comparing the efficiency of these two bio markers for selecting sperm with the lowest level of chromatin damages, it seems that selection based on SAP has significance over others.
