From a man's point of view, a women should never get sterilized unless it's needed medically. The recovery is more involved.

I got spaid and neutered after our second child. I got it done right after work on a Friday, sat around with an ice pack for 2 days and then was back to work on Monday. No muss, no fuss. It's just so much easier for the man that they should be the one doing it.
