Abstract. Ejeh SA, Abu HA, Onyeyili PA, Abenga JN, Abalaka SE, Enefe NG, Eugiene I. 2024. Ethanol leaf extract of Alchornea cordifolia (Euphorbiaceae) effects on reproductive dysfunctions in streptozotocin-induced diabetic male Wistar rats. Asian J Nat Prod Biochem 22: 35-42. Diabetes and some of its treatment agents reportedly induce male reproductive dysfunction in male Wistar rats. Therefore, the study investigated the therapeutic effects of ethanol leaf extract of Alchornea cordifolia (Schumach. & Thonn.) Müll. Arg. on diabetic male Wistar rats. Twenty-five male Wistar rats were used, and 50 mg/kg freshly prepared streptozotocin in cool citrate buffer single intraperitoneal injection was used to induce diabetes mellitus. The rats were grouped into 5 of 5 rats each. Group 1 was normal + distilled water; group II was diabetic untreated; group III was diabetic + 100 mg/kg metformin HCl; and IV and V rats were diabetic and received 100 and 200 mg/kg of the extract orally, respectively. Treatment was done for 28 days; after that, reproductive parameters such as extrapyramidal sperm parameters (sperm motility, count, concentrations, viability, morphology, and acrosome integrity) and hormonal assay (FSH, LH, and Testosterone) were evaluated using a standard protocol. Testicular and epididymal histopathological changes were analyzed using standard procedure. The results revealed a marked impairment in all the parameters evaluated in the untreated diabetic group. However, groups exposed to the ethanol leaf extract of A. cordifolia recorded a significant (p <0.05) improvement in the above-mentioned reproductive parameters, including the restorations of the collapsed epididymal tubules observed in the diabetic untreated group. Therefore, the ethanol leaf extract of A. cordifolia can potentially facilitate and restore reproductive dysfunctions associated with diabetes mellitus complications, hence a possible alternative to synthetic antidiabetic agents.
