FCS stands for Football Championship Subdivision and FBS stands for Football Bowl Subdivision. Teams in the FBS, formerly known as Division 1-A, determine their champion via â¦ ratings, both human and computer.
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.
But you can still get your partner pregnant until your sperm count is zero. You must use another method of birth control until you have a follow-up sperm count test 2 months after the vasectomy (or after 10 to 20 ejaculations over a shorter period of time). Once your sperm count is zero, no other birth control method is necessary.
