德国专家:逛街太多会让男人性无能?

　　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。
