Objective: This study investigated the effects of Tartrazine and Erythrosine (T+E) on the reproductive hormones and expression of some pro-inflammatory cytokines and testicular genes in testis of male Wistar rats.

Methods: 25 male Wistar rats (150-180g) were divided into 5 groups (n=5). Group 1 received distilled water while groups 2, 3, 4 and 5 were treated with T+E (2.5mg/kg, 5mg/kg, 10mg/kg and 20mg/kg) for the period of 23 days. Toxicity studies of the combined dye were investigated by evaluating serum reproductive hormones [Follicle stimulating hormone (FSH), Luteinizing hormone (LH), Testosterone], gene expression and profiling, and testes histology.

Results: male Wistar rats (150-180g) were divided into 5 groups (n=5). Group 1 received distilled water while groups 2, 3, 4 and 5 were treated with T+E (2.5mg/kg, 5mg/kg, 10mg/kg and 20mg/kg) for the period of 23 days. Toxicity studies of the combined dye were investigated by evaluating serum reproductive hormones [Follicle stimulating hormone (FSH), Luteinizing hormone (LH), Testosterone], gene expression and profiling, and testes histology.

Conclusions: This present study reveals that the dyes could impair testicular function as evident in the up-regulation of pro-inflammatory cytokines and down-regulation of TESK-1 gene expression and architecture of the testes leading to Orchitis.
