The chances of miscarriage or possible effects on children are lessened, however, if the woman is younger than 35.
As for reversal of vasectomy, it depends on the time after vasectomy, and experience of the surgeon. One specialist surgeon, who has performed this procedure on 700 men in 3 years, has a high success rate, including a forum member.
