There are three primary ways a pregnancy can occur after a vasectomy: 1  Having sex without contraception before the manâs sperm count is confirmed to be zero. 2  Natural reversal, also known as recanalization. 3  Surgical error.
Mom Answers. Studies have shown that tubal ligation (tying of the fallopian tubes) is not a 100% guarantee of contraception. There's still at least a 1% chance of getting pregnant after your tubes are tied. This risk then increases to about 1.8% after 10 years. It has also been noted that most pregnancies occurring after ligation are ectopic in nature, meaning that the pregnancy occurs at the fallopian tube instead of the uterus.
