My husband had a vasectomy in January 2012. He provided a semen sample 3 months later and it was negative. He provided a second sample one month after that and again, it was negative. I’m assuming negative means zero sperm count. Can we be confident enough to stop using any other form of contraception?
Yes, you can stop using a backup contraceptive, but since recanalization can very rarely happen, even after 2 negative semen analyses, get a third semen analysis at a year or two post vasectomy.
From Dr. Lisa Haddad: “Honestly, I am not sure. I usually say after 2 negatives, you are good. I may VERY well be wrong.”
