Abstract:

Objective To explore the preventive role of tea polyphenol (TP) on the chronic alcoholism induced sperm damage and the potential mechanisms. Methods Forty male Kunming mice were randomly divided into chronic alcoholism (CA) group, TP low-dosage (TP-L) group, TP high-dosage (TP-H) group and normal control (NC) group. Eight hours after daily alcohol administration, the mice in CA, TP-L and TP-H groups were treated with water, 1% TP or 2% TP respectively. The mice in NC group were administered with water twice a day. 90 days later, sperm suspension was prepared to detect sperm density, activity ratio and malformation ratio; Bcl-2 and Bax expression were observed in testicular tissue via immunohistochemistry. Results In CA group, the density, activity ratio of sperm and ratio of Bcl-2 positive cells in testicular tissue were lower, the ratios of sperm malformation and Bax positive cells in testicular tissue were higher than that of NC group. Above changes were reversed in the TP-L and TP-H groups. Moreover, this benign effect showed a positive correlation with dosage. Conclusion Tea ployphenol could alleviate alcoholism induced sperm damage. This effect might relate with the Bcl-2 and Bax expression during spermatogenesis.
