Single injection of streptozotocin (STZ) resulted diabetes mellitus which was reflected here by the levels of fasting blood glucose and serum insulin. Moreover, this experimental diabetes also resulted testicular dysfunctions evaluated by count, viability and motility of sperm as well as by the activities of key enzymes for androgen synthesis. Diabetes induced testicular oxidative stress has been indicated here by the monitoring of testicular peroxidase and catalase activities as well as by quantification of TBARS and CD of testis. Testicular glucose was increased and leydig cell nuclear area was decreased in STZ induced diabetes. Treatment of herbal formulated drug named as MTEC consist of aqueous-methanol extract of Musa paradisiaca, Tamarindus indica, Eugenia jambolana and Coccinia indica to streptozotocin induced diabetic rat at the ratio of 2 : 2 : 1 : 1 at the dose of 60 mg/d for two times a day for 14 d resulted a significant protection in fasting blood glucose and serum insulin levels (p<0.05) along with correction of testicular above parameters towards the control level (p<0.05). This herbal formulated drug has no general toxic effects on the body weight, as well as on the activities of serum glutamate and pyruvate transaminases in serum. The results support the validity of this herbal drug for the management of testicular disorders noted in diabetic state.
