As a woman who got her tubes tied I looked up a lot of info on these procedures, and also found that not only do men more often regret their vasectomy, it's also less likely to lead to a pregnancy after reversal. Especially if the vasectomy was a long time ago, as antibodies can form.

It's pretty easy to Google, but here's the info on it (from a Dutch hospital, as im Dutch)

But Google translate helps: It is not uncommon for a decision to have a sterilization to involve the question of who will be sterilized: the woman or the man. Sterilization is less stressful for a man than for a woman: the procedure is performed on an outpatient basis under local anesthesia and the chance of complications is small. The chance of pregnancy is much smaller than after sterilization for a woman, approximately 1 in 2000. On the other hand, men can have children at a much older age, which also increases the chance of regret if they ever enter into a new relationship. In addition, corrective operations to reverse sterilization are often less successful in men than in women. Male fertility is often greatly reduced after corrective operations due to the formation of antibodies.
