Background: The aim of the current study was to assess the mRNA levels of two mitochondria-related genes, including nuclear-encoded NRF1 (nuclear respiratory factor 1), mitochondrial transcription factor A (TFAM), and mitochondrial-encoded cytochrome c oxidase subunit 1 (MT-CO1) genes in various stages of the human oocyte maturation. Methods: Oocytes were obtained from nine infertile women with male factor undergoing in vitro fertilization (IVF)/intra-cytoplasmic sperm injection protocol. Mitochondrial-related mRNA levels were performed by single-cell TaqMan Real-time PCR. Results: the expression level of the target genes was low at the germinal vesicle stage (P>0.05). Although the mRNA level of NRF1 gene remained stable in metaphase I, the mRNA level of TFAM and MT-CO1 increased significantly (P<0.05).In metaphase II, the expression level of all genes increased compared to metaphase I (P<0.05). Conclusion: The overexpression levels of NRF1, TFAM, and MT-CO1 genes are related to the oocyte maturation. Therefore, the current study could be used clinically to improve the success rate of IVF.
