my hubby is still intact but i hear that it is possible. the success rate of a vasectomy depends on the method that they use, but i hear that it is still possible for them to shoot out some soldiers from time to time.
my aunt knew a woman who had a hysterectomy once and then found out she was prenant months later because unbeknownst to her doctor, she had 2 sets reproductive organs (2 uterus' and 4 ovaries). bizzaro, but hey, anything is possible.
my boyfriend said that his dad had gotten one and his mom still got pregnant with his brother afterwards....but i dunno...my dad got one years ago and my parents haven't had any problems with poppin out any more kids haha
