My dh said a long time ago that if either of us were to have a procedure done, it would be easier for him than for me. Since neither of us want to have our fertility taken away permanently, it is not an option that we are considering in the foreseeable future. Extended breastfeeding does not work for us, AF shows up within two to three months after my baby's birth. We do NFP most of the time. Both procedures are invasive, but if you had to choose the lesser of two evils a vasectomy would probably be less invasive.
