Objective@#To investigate the mRNA and protein expressions of outer dense fiber 2 (ODF2) in the sperm of the asthenospermia patient and their differences from those in normal healthy men.@*METHODS@#According to the WHO criteria, we collected semen samples from 45 asthenozoospermia patients and 15 normal healthy volunteers. Using computer-assisted sperm analysis (CASA), we divided the semen samples from the asthenospermia patients into a mild, a moderate and a severe group, and determined the mRNA and protein expressions of ODF2 in different groups by RT-PCR and Western blot.@*RESULTS@#Compared with the normal healthy men, the expression of the ODF2 gene showed no statistically significant difference in the mild asthenospermia group (1.112 0 ± 0.525 5 vs 0.688 0 ± 0.372 0, P >0.05) but remarkably decreased in the moderate (0.483 3 ± 0.186 3, P 0.05), but markedly lower than in the moderate (0.145 4 ± 0.053 6, P <0.05) and severe asthenospermia patients (0.122 7 ± 0.045 7, P <0.01), which was consistent with the results of RT-PCR.@*CONCLUSIONS@#Decreased mRNA and protein expressions of ODF2 in the sperm are positively correlated with declined sperm motility of the asthenospermia patient, which is suggestive of the involvement of the ODF2 gene in the regulation of sperm motility.
