Im young so I might not have the perspective that comes with parenthood or age, but as far as the legality of it is concerned a vasectomy is not that different than an abortion there are laws protecting women from needing the consent or even knowledge of anyone, the father or her parents when seeking an abortion I think the same thing applies to all reproductive surgeries. But I also agree with the rest of you that any relationship where one person feels they can or have to keep something like that a secret is not a healthy relationship. So I think its only a ethical / moral question not a legal one but from my perspective it would be far worse if the wife didnt want more children and the husband did something (poking holes in condoms or whatever) to make sure she would get pregnant.
