Contraception--Tubular gels
避孕--管状凝胶
Researchers want to make reversible vasectomies a one shot deal
研究人员希望使可逆输精管切除术成为一种一次性解决方案
The most reliable means of contraception for men--and one that cannot fail or be forgone in the heat of the moment--is a vasectomy.
对男性来说,最可靠的避孕方法是输精管结扎术,这是一种不会在一时的狂热中失败的方法。
But the procedure is largely irreversible: it involves stopping the flow of sperm from the testes by cutting conduits known as the vas deferens and sealing them or tying them off.
但这一过程在很大程度上是不可逆转的:它包括通过切割被称为输精管的管道来阻止精子从睾丸流出,并将它们密封或打结。
A reconnection, after a reconsideration, is no small task.
在重新考虑之后,重新建立联系并不是一项小任务。
Researchers are now examining a different tack: blocking the vas deferens using compounds that combine to form a barrier that can later be removed.
研究人员现在正在研究一种不同的方法:使用化合物来堵塞输精管,这些化合物结合在一起形成一道屏障,以后可以被移除。
Lab trials have involved four separate injections to establish a sperm-proof barrier, which could later be dissolved using a blast of focused, infrared light.
实验室试验包括四次单独的注射,以建立防精子屏障,之后可以用一束聚焦的红外光来溶解它。
