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.

据英国《每日邮报》报道，科学家表示，绿茶能掩盖动物体内真实的睾酮水平。

研究发现，绿茶提取物能使体内激素浓度最多降低30%。

奥运会兴奋剂检测官员表示，要谨防运动员在例行药检中饮用绿茶掩盖升高的睾酮水平。睾酮常被用来增加肌肉。

世界反兴奋剂组织科学主任奥利弗·拉宾表示，相关变革势在必行。
