Welcome to EmpowHER. Sorry to hear this. Even though, a vasectomy is considered a permanent form of birth control to make a man unable to father a child. It is a surgical procedure in which the tube that carries the sperm from the testes to the urethra is cut or sealed off to prevent sperm from being released during ejaculation. Researchers say that a study shows that like other birth control methods, vasectomies are not always 100% effective. It's important for you and your husband to be seen by a doctor and explain all your symptoms.
