Notably, distinct RBP gene clusters exhibit significant differential expression, particularly in Sertoli cells as they mature from neonatal to adult stages. Our analysis has revealed temporally-regulated RBP clusters that correlate with the developmental progression of Sertoli cells and the advancement of spermatogenesis. Moreover, we have established links between specific RBPs and the pathogenesis of non-obstructive azoospermia (NOA) through the regulation of alternative splicing (AS) events. Additionally, RPL10, RPL39, and SETX have been identified as potential diagnostic biomarkers for NOA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This research provided an in-depth look at RBP expression patterns during human testis development and spermatogenesis.
