PURPOSE: Idiopathic asthenozoospermia is considered as one of the causes of male infertility and characterized by reduced sperm motility. For a better determination of pathogenic mechanism of asthenozoospermia, the exploration of differentially expressed proteins in normal sperm motility and idiopathic asthenozoospermia was conducted in our study. METHODS: Sperm proteins were extracted and isolated by two-dimensional electrophoresis. All significantly changed protein spots were picked up from 2D gels and identified by tandem mass spectrometry. Sixteen of the thirty-three total differentially expressed protein spots were successfully identified by matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry. RESULTS: Sixteen proteins identified belonged to 15 unique protein groups. GRP78, lactoferrin, SPANXB, PGK2, flagellin, DJ-1, XPA binding protein 2, CAB2, GPX4, and GAPDH were the first to be identified as differentially expressed proteins in idiopathic asthenospermia patients. Meanwhile, the analysis of quantitative RT-PCR was carried out to compare the protein levels, and the results indicated that the expression levels of the gene and protein were not entirely consistent. CONCLUSIONS: These experimental results expand the scope of the protein database, generating targets for further investigation of the pathogenic mechanism of idiopathic asthenozoospermia.
