Abstract：Objective To study sperm mRNA transcript expression of CRISP2 gene in the semen of patients with different types of spermatogenetic failure. Methods A total of 150 male infertility patients were divided into normal group, asthenozoospermia group and oligozoospermia group(n=50 for each group). Total RNA was extracted from sperm cells. Re-al-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) method was used to detect CRISP 2 gene mRNA levels in three groups. Results There was a significantly higher expression of CRISP2 in normal group (10.281 ± 2.173) than that of asthenozoospermia group (2.092±0.969, P<0.05). There was no significant difference in the expression of CRISP2 between normal group and oligozoospermia group (9.420±2.794, P>0.05). The relative expression of CRISP2 was sig-nificantly lower in asthenozoospermia group than that of oligozoospermia group (P<0.05). Conclusion The CRISP2 expres-sion was significantly different in patients with different types of spermatogenic failure. The reduced expression of CRISP 2 may lead to the decreased sperm motility.
