Abstract: 【Abstract】 Objective〓To investigate the protective role of spermatogenesis by cremaster-sparing tension-free hernia repair in a rat model. Methods〓Twenty-four adult SD rats were randomized into 4 group, control group, sham group, operation group (OP1 and OP2, again). Op1 performed surgery by cremaster-sparing tension-free hernia repair, and cremaster was cut during operation in Op2 group. The animals were sacrificed in 90 days after experimental animal model establishment. The testiculartissue was taken for H.E staining and the assessment of quantity changes of spermatogeniccells in each group. The pathological changes of the testis in each group were observed. Results〓The testis of rats group OP2showed degenerative changes. The germinal epithelium disorder, the number of germinal cells were decreased, and the number of haploid cells and diploid cells were significantly decreased, as compared with group OP1 and group sham group (all P values were less than< 0.05). Conclusion〓Cremaster could be protective role on the spermatogenic function in rats underwent tension-free hernia repair. It is maybe an important step for hernia repair to protect the continuity and integrity of cremaster.
