Protective effects of honey compound syrup on busulfan-induced azoospermia in male rats

Abstract

Objective: To evaluate the protective effects of honey compound syrup on sperm count and testis tissue in rats. Methods: Thirty rats were randomly assigned to five groups. The control group received 1 mL normal saline with dimethyl sulfoxide intraperitoneally; the busulfan group received busulfan 10 mg/kg body weight at the first and twenty-first days of the experiment via intraperitoneal injection; the last three groups received busulfan 10 mg/kg body weight to induce azoospermia, and then received 1.0, 1.5, or 2.0 mg/kg honey compound syrup, respectively, after induction of azoospermia. After administration, the testis and epididymis of all rats were removed. Then, reproductive organ weight and sperm parameters (sperm concentration, epididymal sperm reserve and daily sperm production) were measured. After hematoxylin-eosin staining, seminiferous tubule cells and diameters were assessed. Results: Busulfan damaged the testis tissue and impaired spermatogenesis. Administration of honey compound syrup in three doses improved testis tissue and spermatogenesis. The protective effects of honey compound syrup may relate to the antioxidant properties of honey and other compounds in this syrup. Conclusions: Administration of honey compound syrup could be an ameliorative agent for the side effects of chemotherapy drugs such as busulfan on the male reproductive system.
