IMO 1-2% rate is quite high for an unnecessary procedure, I am glad OP is talking about it to make more people aware of this.

What do you mean by "unnecessary"?

Unnecessary to be healthy, or unnecessary as in "something you do you should not" (say, like injections in the lips to make them bigger)?

Unnecessary to be healthy. If someone doesn't want a kid, there are other forms of birth protection available which can be relied on and they are quite effective if used as advised.
