| Abstract | ||
| Comparing the Sertoli cell ratio, diameter and quality of the eight stages of seminiferous epithelial cycle in stressed rabbit to the normal control group. It was resistant to heat, type B sharply affected. In the process of spermatocytogenesis, there were three target stages to heat stress application. Stage three (pachytene transformation) and stage five ( zygotene to pachytene transformation) and the secondary sper matocytes. The zygotene cells were found to be heat resistant. Although the spermiogenesis were severely affected, type A rounded spermatids were unchanged. The processes of accumulation of dusty chromatin (Type B), the spermatid eleongation (Type C) and sper matid maturation (Type D) were severely damaged. | ||
