Objective:To observe the changes in semen quality before and after operation in the officers and soldiers stationed at coastal areas with clinical varicocele，and to evaluate the outcome of operation.Methods:According to the results of the color Doppler ultrasound，a total of 113 patients with clinical left varicocele who underwent high ligation of the spermatic vein in the Department of Urology of the Beidaihe Rehabilitation and Recuperation Center of PLA Joint Logistics Support Force were divided into three groups：clinical grade Ⅰ（ n=31），clinical grade Ⅱ（ n=36），and clinical grade Ⅲ（ n=46）. The semen qualities of all patients were analyzed before and after operation. Results:There was no significant change in semen quality before and after operation in the clinical grade Ⅰ group（ P>0.05）；the semen quality in the clinical grade Ⅱ group was significantly improved after operation（ P<0.05）；the semen quality in the clinical grade Ⅲ group after operation was generally improved（ P<0.05）. There was no significant difference in semen volumes or sperm deformity rates before and after operation among the three groups（ P>0.05）. Conclusion:The incidence of clinical varicocele in officers and soldiers stationed at coastal areas is significantly higher than that in the general population. The improvement of postoperative semen quality is closely related to the severity of preoperative varicocele. Ultrasound combined with routine semen examination can effectively evaluate the improvement of postoperative semen quality.
