MicroRNA (miRNA) and target genes evaluation were carried out using <jats:italic>in silico<\/jats:italic> prediction analysis, Reverse transcription-quantitative PCR (RT-qPCR) validation, and Western blot confirmation.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The expression levels of miRNA-19a\/b-3p were significantly up-regulated and 51 target genes were significantly down-regulated in oligoasthenozoospermic men compared with age-matched normozoospermic men as determined by RT-qPCR. Correlation analysis highlighted that sperm count, motility, and morphology were negatively correlated with miRNA-19a\/b-3p and positively correlated with the lower expression level of 51 significantly identified target genes. Furthermore, an inverse correlation between higher expression levels of miRNA-19a\/b-3p and lower expression levels of 51 target genes was observed. Consistent with the results of the RT-qPCR, reduced expression levels of STK33 and DNAI1 protein levels were identified in an independent cohort of sperm samples collected from men with oligoasthenozoospermia.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> Findings suggest that the higher expression of miRNA-19a\/b-3p or the lower expression of target genes are associated with oligoasthenozoospermia and male infertility, probably through influencing basic semen parameters.
