Numerous evidences suggested that microRNAs (miRs) could play an active and significant role during spermatogenesis. Cysteine-rich secretory protein (CRISP3) has a role in inflammatory response and is extremely over-expressed in adolescents with varicocele seminal plasma and modified semen analysis. Nowadays, the miRs expressions association with their target genes is well recognized. The aim of this study was evaluating the association of CRISP3 and four candidate miRs among teratozoospermia (TZ) infertile men. First, we have selected four miRs, miR-182-5p, miR-192-5p, miR-204-5p, and miR-493-5p bioinformatically. After that, RNA was extracted from semen samples of 21 TZ patients and 20 normozoospermia (Norm). Then, their expression levels were assessed using real-time polymerase chain reaction method. In the next step, we quantified the expression of two CRISP3 protein isoforms, targeted by these miRs, using western blotting. According to our results, up-regulation of miR-182-5p, miR-192-5p, and miR-493-5p was observed. MiR-182-5p, miR-192-5p, and miR-493-5p showed good AUC values which can be introduced as possible biomarkers of TZ. In addition, the expression level of the CRISP3 glycosylated (31 kDa) isoform was significantly lower in TZ patients than Norm ones. Notably, in TZ patients, there was a possibly positive correlation of glycosylated CRISP3 expression with normal sperm morphology. According to our results, CRISP3 protein can play a significant role in male infertility especially in maturation formation of spermatozoa. Also, deregulation of the studied miRs, miR-182-5p, miR-92-5p, and miR-493-5p, can suggest a regulatory network between these miRs and CRISP3 isoforms and suggest their regulatory roles in male infertility.
