Figure 6.

The effect of streptozotocin, crocin, and streptozotocin plus crocin on the germinal layer of seminiferous tubules (×40). Normal seminiferous tubules structure and germinal layer thickness in the normal control group (a) and crocin (150 mg/kg) (c) were seen. In the diabetic control group (b) decreased in germinal layer thickness and the sperm cell was seen (blue arrows). In the diabetic (50 mg/kg) group (d) a normal seminiferous tubules structure was seen. The black arrows in figures show the normal germinal layer thickness
