Now men have the perfect excuse to avoid shopping.It could make them impotent。

　　According to Daily Telegraph on June 29, researchers have made the startling discovery that a gender bending chemical compound is present in the ink on some till receipts. And the levels of hazardous substance Bisphenol A (BPA) can be high enough to suppress male hormones in the body. The compound, used to make ink visible on thermally sensitive paper, is ingested by men when they handle the receipts and then touch their mouths or handle food。

　　Prof Frank Sommer, 42, a Berlin-based urologist, explained, "A substance like that could shift the balance of the sex hormones in men towards oestrogen." In the long term, this leads to less sexual drive, encourages the belly instead of the muscles to grow and has a bad effect on erection and potency。

　　BPA is also used in food cans, shower curtains, toys and babies bottles. It is linked to disorders associated with metabolism, fertility and neural development. In addition to suppressing male hormones it is thought that it may be triggering early puberty in girls - and putting them at greater risk of cancer and diabetes。

　　如今，男人们有了一个不逛街的绝佳理由—男人经常逛街购物会导致性无能。

　　据英国《每日电讯报》6月29日报道，研究人员惊奇地发现一种有易性作用的化合物存在于商场收银机开出的购物发票中。这种发票的墨水里含有有害化学物质双酚A(BPA)。该物质会抑制雄性激素分泌。以前，这种化合物用做显影剂。当男人触摸发票后，双酚经由手、口而被身体吸收。

　　德国柏林42岁的泌尿科专家弗兰克•索莫教授表示，该物质会打破雌雄激素的平衡，使雌激素分泌过量。时间一长，会导致男性不长肌肉长肚腩、性欲减退、阳痿。

　　除了收银机发票墨水之外，罐头食物内壁、淋浴帘、玩具甚至奶瓶里都有双酚A。另外，有害化学物质双酚A还与新陈代谢紊乱、肥胖和神经系统发育不良关系密切。经常接触双酚A也会让女孩过早发育，并增加她们患癌症和糖尿病的风险。
