getting pregnant after vasectomy?

My husband had a vasectomy a year ago....only snipped (not burned) we were told that the procedure is reversible. I wanna know if any of you have/know someone who has gotten pregnant after having a vasectomy. We are thinking in 3 years of trying for a baby. Please no amarrada remarks about how "irresponsible" getting a vasectomy is. I have adverse reactions to birthcontrol. Hormonal and Non.
