据英国《太阳报》4月1日消息，贝尔法斯特皇后大学研究人员日前表示，通过实验证实那些服用伟哥以提高性能力的男人们在获得愉悦的同时可能也在损害着自己的生殖能力。

专家们表示，他们通过对许多服用了伟哥后的男人的精液的研究发现，作为医治阳痿特效药的伟哥，在某种程度上抑制了精子的形成，并降低了精子的活动能力。

专家们特别对那些纯粹只为取乐而使用伟哥的年轻男子发出警告，称伟哥对他们的生殖能力的损害程度远甚于患者。该研究小组负责人森纳·路易斯博士表示，“伟哥主要是针对阳痿患者，尤其是那些想生育子女、又上了点年纪的人。但不幸的是，现在它却成了一种助性的大众药物。我们的忠告就是：如果你还想生育子女建立家庭的话，在使用助情药时就应该慎重再慎重。”

Viagra in fertility warning

MEN who take Viagra to pep up their sex lives could be harming their fertility, scientists warned yesterday.

They said lab tests had shown the anti-impotence drug can reduce the ability of sperm to fertilise eggs.

The researchers from Queen's University, Belfast, added that the alert applied particularly to younger men who use Viagra "recreationally".

Team leader Dr Sheena Lewis said: "Viagra was aimed at men with impotence problems, primarily older men not interested in having children. Now it has become popular for sexual enhancement.

"Our message is that caution should be taken when using recreational drugs if you are hoping to start a family."

The tests -- which support earlier studies on mice -- also raise questions for fertility clinics.

Many give Viagra to men to help them provide semen samples.
