I had a vasectomy 20 years ago. Can I impregnate any one?

I have slept with women but none got pregnant. I slept with a woman and now she's 7 weeks pregnant. I don't know if it's mine or her boyfriend's. I told her it can't be mine, but she's adamant. Is it possible that I am fertile?

Check semen analysis or have semen examined under a microscope to check for any sperm. If no sperm, then you are fine.

Yes. But the odds after twenty years are extremely low. Get a semen analysis and you will have your answer!

One in 2000 vasectomies fail long term due to a process called recanalization. A semen analysis can help you determine if you have sperm in your ejaculate.
