A vasectomy can be reversed, though it's a more invasive procedure. Moreover, even when the surgery is successful, conceiving a child is not always easy. You should be fairly certain that you do not want additional children prior to having a vasectomy. Consider sperm banking as a precaution. Should you decide to have a child the sperm is thawed and placed into the women's cervix through a process called artificial insemination. This is not the same as the very costly in vitro fertilization.
