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精管，这些化合物结合在一起形成一道屏障，后可除。

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

另一个患上了精子肉芽肿，这基本上是输精管外一团精子，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， 实际上只有避输精管切除术，外科医生会关闭输精管， 让精子从睾丸中向上游出。

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.

它包括通过切割称为输精管管道来阻止精子从睾丸流出，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.

所他们可将这种凝胶注入输精管，然后形成一个塞子， 本质上它做了同样事情，但你不必切割它。
