My husband had a vascectomy five years ago… no problems. I am 30 years old and I have not gotten my period yet. I have tender breast, pimple like things on my areola, bloating, fatigue and I have been sick every morning for 2 weeks. I took a test a week or so ago and it was negative. How common is pregnancy after a vascectomy. Also, he never went for follow-up appointments to have sperm level checked!”
Getting pregnant with someone who’s had a vasectomy is very unusual, but not impossible.
A 2004 study of a group of 540 women found that 6 of them were pregnant after a husband’s vasectomy, a failure rate of .01 percent. Other studies have found the failure rate for vasectomies to be about 1 in 2,000 in the few months after the procedure is performed when couples have unprotected sex too soon after surgery with still live sperm around. Late vasectomy failures are even more unusual, estimated at less than 1 of 4,000 procedures.
Also what these studies don’t appear to account for is the possibility of a father other than the study subjects’ husbands.
With late failures, what can happen is something called “late recanalization,” which is when the vas deferens actually manages to grow back together, usually as the result of poor surgical technique. So it is much more likely is that your symptoms are caused by other things, like PMS or a mild flu. Still, if you still don’t have your period within a month after you were expecting it, you may want to give your health care provider a call—and have your husband’s sperm count checked, just for your peace of mind!
