How it's used
Refers specifically to the surgical removal of the testicles, primarily used in veterinary contexts for pets. While it can apply to humans in historical or extreme medical contexts, using it in casual conversation about people is considered highly offensive or derogatory. It is much more common to hear people use the term 絕育 when discussing pets in a general sense.
Examples
Has the dog had its castration surgery yet?
The vet suggested castrating the cat.

castration surgery
Common mistake
Learners often confuse this with 絕育, which is a broader term for sterilization that can apply to both males and females. Using 去勢 for a female animal is anatomically incorrect.
