Abstract
miRNAs play a critical role in the regulation of highly orchestrated gene expression profiles during spermatogenesis and early human embryonic development. However, there is much less information available on the effects of sperm-borne miRNAs on human embryonic development than on spermatogenesis. This study was designed to assess the relationship between two sperm-borne miRNAs (miR-34c and miR-149) and preimplantation embryo development in conventional in vitro fertilization treatment. A positive correlation was seen between a decreased level of miR-149 and a higher percentage of good-quality embryos on day 3 in conventional in vitro fertilization treatment (P < 0.0001), but no correlation was seen between miR-34c and a higher percentage of good-quality embryos (P = 0.1084). Receiver-operating characteristic curve analysis and logistic regression analysis showed that sperm-borne miR-149 with decreased expression was significantly associated with a high rate of good-quality embryos (area under the curve 0.781) (odds ratio: 0.078, 95 % confidence interval: 0.024-0.259, P < 0.0001). Our results demonstrate that the expression profile of miR-149 with significantly decreased expression could be used as a first indication of early embryonic development and may provide novel insight into the biological background of idiopathic infertile males.
