  • 全球首个男性避孕药或将推出

    就是射精时将成熟的精子运送到尿道的部位。Sharma对《印度斯坦时报》说,这样做的目的是要阻挡精子,因此男人就不可能让女人怀孕了,有效期长达13年。[/cn] [en]In some ways, it’s similar to a vasectomy, a surgery that involves cutting or tying the vas deferens to stop sperm from entering the urethra and getting passed along to a female partner. But reversing a vasectomy requires more surgery, and the RISUG treatment can reportedly be reversed simply with another shot that breaks down the gel. It could cost as little as $10 in developing countries.[/en][cn]在某些方面这有点类似输精管结扎术,那是一种手术,通过切断或扎住输精管以阻止精子进入尿道从而进入女性性-伴侣的体内。但想要达到逆向作用还需要进行手术,而据报道RISUG疗法的逆向方法很简单,只需要再注射能溶解凝胶的物质就可以。发展中国家的注射费用仅为10美元。[/cn]   翻译:菲菲

And, as you've no doubt guessed, it's also a main contributor to ozone depletion and global warming.[/en][cn]现在这种气体主要来源是人类的农业活动,比如使用廉价的氮肥。如你所料,它也是臭氧消耗和全球变暖的主要原因。[/cn] [en]To make matters worse, we've seriously underestimated its use.
