Actually, the legality of vasectomies has never been up for debate in the US--it's legal as long as you're 18 years or older, and will continue to be so.
It's why a LOT of people are upset about the double standard of reproductive health care for people with uteruses, because those with a vas never have to request permission to receive a vasectomy (other than referral from a primary care physician like all specialized surgeries). However, those with a uterus have, depending on the state, to receive written or in-person permission from their husband/father or will otherwise be given a TON of shit by their doctors if they want a hysterectomy. Go figure, right?
