Is it possible to get pregnant after 12 years is a man got a vasectomy?

Yes, it is possible, though rare, for a man to get someone pregnant after a vasectomy. In some cases, the vas deferens can spontaneously reconnect, or sperm may remain in the reproductive tract for a time after the procedure. Additionally, if the vasectomy was not successful or properly performed, there may still be a chance of pregnancy. If pregnancy is a concern, it's important to discuss options with a healthcare provider.
