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的一团精子，可能会变得疼痛。

But the researchers looked at other rhesus monkey health data they had collected, too, and found that sperm granulomas seemed to be more common in monkeys with vasectomies than in the group with Vasalgel.

但研究人员也查看了他们收集的其他恒河猴健康数据，发现精子肉芽肿似乎在接受输精管切除术的猴子中比接受 Vasalgel 的猴子更常见。
