Article Abstract

Background: MicroRNA (miRNA) is small endogenous, single strand RNA molecules that regulate gene expression at post-transcriptional level through several mechanisms to affect key cellular event including male germ cells differentiation, proliferation, development and apoptosis. Mutation and/or aberrant expression of miRNAs have been associated with progression of various disorders, including infertility.

Objective: The purpose of this research was to study the estrogen receptor beta (ERβ(, hsa-mir-21 and, hsa-mir-22 expression level in oligospermic infertile and control fertile men and correlation between them.

Materials And Methods: In this study, the change in mir-21, mir-22 expression and their common target gene (ERβ) expression levels were evaluated in oligospermic infertile men (n= 43) compared with 43 age matched healthy control by Real-Time PCR methods.

Results: Expression analysis by qRT-PCR test on miRNA have identified that mir-21, mir-22 levels were significantly higher than those in normal controls (p<0.0001) and ERβ expression level significantly decreased in comparison with the normal group (p<0.0001).

Conclusion: Our study showed that mir-21 and mir-22 are indirectly involved in spermatogenesis by regulating of the estrogen receptor and might have a diagnostic and prognostic value in men infertility.
