Methods: A total of 120 male infertility patients with aspermia, asthenozoospermia and oligozoospermia in Shaanxi Province were selected, and the six sequence-tagged sit of Y chromosome AZF were detected by multiplex polymerase chain reaction (PCR) and Cytogenetic analysis was performed with the GTG banding technique. A total of 130 healthy men were treated as the control group. Result: Among 120 infertile patients tested, 11 cases had Y chromosome gene microdeletions, with a detection rate of 9.2% (11/120), including 10 cases with AZFc region deficiency;one case of Y chromosome gene microdeletion was detected in the control group of 130 cases, with a detection rate of 0.8% (1/130). This case is due to AZFc region deficiency. The detection rate of the control group was significantly lower than that of the experimental group, and the difference was statistically significant (P 0.05). Conclusion: In male infertility patients in Shaanxi region, the deletion of the展开更多
