Scientists say that green tea can help mask the levels of testosterone in the body, the Daily Mail reported.

A study found extracts contained in the beverage reduced concentrations of the hormone by up to 30 percent.

Olympic doping officials have now raised concerns that athletes could use tea to hide increased levels of testosterone from standard drugs tests. Testosterone is commonly used to build muscle.

Olivier Rabin, scientific director of the World Anti-Doping Agency, said that changes could be necessary.

據英國《每日郵報》報道，科學家表示，綠茶能掩蓋動物體內真實的睪酮水平。

研究發現，綠茶提取物能使體內激素濃度最多降低30%。

奧運會興奮劑檢測官員表示，要謹防運動員在例行藥檢中飲用綠茶掩蓋升高的睪酮水平。睪酮常被用來增加肌肉。

世界反興奮劑組織科學主任奧利弗·拉賓表示，相關變革勢在必行。
