Abstract Objective: To investigate the relationship between the diabetes of men and their semen quality. Methods: The data of 168 infertility men from September 2016 to February 2017 were retrospective analyzed. The included men were divided into group A (74 cases with normal fasting glucose), group B (62 cases with fasting glucose impaired), and group C (32 cases with diabetes) according to the level of fasting blood glucose. CASA system was used to detect the semen parameters of all men. Results: There were significant difference in total number of spermatozoa, the sperm concentration, and the percentage of sperm moving forward (P<0.05). The total number of spermatozoa of men in 20-25 years old was the lowest. As for the men in 26-30 years old, the percentage of sperm moving forward of men in group B and C was significant lower than that of male in group A (P<0.05). Correlation analysis showed that the sperm concentration, total sperm count, and the percentage of sperm moving forward of man was significantly negative correlation to fasting glucose concentration (P<0.05). Logistic regression analysis showed that the risk of abnormal semen quality of overweight or obesity men in group C was 3.667 times of that of normal weight men in the group A, and the interaction index (S) of overweight or obesity with hyperglycemia was 1.43, RERI was 0.798, and attribution percentage (AP) was 21.76%. Conclusion: Hyperglycemia can decrease the semen quality, and hyperglycemia and overweight or obesity may increase the risk of abnormal semen.
