Researchers are now examining a different tack: blocking the vas deferens using compounds that combine to form a barrier that can later be removed.

使用化合物来堵塞输，些化合物结合在一起形成一道屏障，以后可以被移除。

Another developed a sperm granuloma, which is basically a lump of sperm outside the vas deferens that could become painful.

另一个患上了肉芽肿，基本上是输外一团，可能会变得疼痛。

For biosex males, there’s really only condoms and vasectomies, where a surgeon shuts the vas deferens tubes that let sperm travel up and out from the testicles.

对于 biosex 男性， 实际上只有避孕套和输切除术，外科医生会关闭输， 让丸中向上游出。

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.

它包括通过切割被称为输道来阻止丸流出，并将它们密封或打结。

So they have this ability to inject this gel into what's called the vas deferens, and it makes this plug, so then essentially it does the same thing, but you're not cutting it.

所以他们可以将种凝胶注入输，然后形成一个塞， 本质上它做了同样事情，但你不必切割它。
