Hello,
Anything is possiable...but probable...no, not unless he lied, had a reversal surgery or you slept with someone else or had invetro...there might be 1 in 500,000 that it did not hold or was not done correctly... this was from my memory not stats from the EXPERTS...Do you want children, did he now change his mind on kids....Even if you do not have natural children there are plenty of beautiful babies out there looking for a mommy and daddy...maybe after your boyfriend is your husband you can "WORK ON THE PROJECT"...lol Have a wonderful Blessed Day!!!! GOD BLESS!!!! loimmarmar
Has he had a test after the vasectomy that showed a sperm count of 0? If so, then you would not get pregnant from him, unless he had a surgery to reconnect the tubes that were clipped.
