Background and Objectives Diabetes mellitus is a metabolic disease which causes disorders in the reproductive system. Recent studies have revealed that the main components of saffron like crocin and safranal have several physiological effects on different biological systems. Given the role of crocin in the modulation of antioxidant defense system, this study aimed to determine the effect of crocin on pituitary-testicle hormonal axis in alloxan-induced diabetic male rats. Subjects and Methods In this experimental study, 28 Wistar male rats were allocated into 4 equal groups: control, diabetic control, and two diabetic groups treated with crocin at two concentrations. Induction of diabetes in the diabetic control and the diabetic groups treated with crocin was done by an intraperitoneal injection of 240 mg/kg alloxan. Crocin at concentrations of 50 and 100 mg/kg [0.5 ml] was intraperitoneally injected into the two diabetic groups for 25 days. Saline solution [0.5 ml] was injected into the animals in the control and diabetic control groups for 25 days. At the end of the treatment period, serum levels of LH, FSH, estrogen, testosterone and DHT were measured by ELISA. Statistical analysis was carried out using one-way ANOVA and Tukey post hoc test. P <0.05 was considered statistically significant. Results Compared with the diabetic control group, administration of crocin at concentrations of 50 and 100 mg/kg significantly increased serum levels of LH, FSH, estrogen, and DHT testosterone in a dose-dependent manner [p<0.05]. Conclusion The results show that by increasing the activity of pituitary-testicle hormonal axis, crocin improves hormonal disorders in diabetic rats.
