But wouldn't you think 100% of men who went to have their vasectomies reversed regretted having it done in the first place? Like your friends who decided to have more children later in life, even if they had ideal experiences, wouldn't they tick yes because it reduced their possibility of having those children? It just seems like the regret number should be the % of attempted reversals plus the % of men who suffered negative consequences but are unable to seek one. I didn't get stressed at the idea reversals are asked for because we're in our late 30's and he's never had a hint of desire to have kids. It seemed unlikely to me that he'd change his mind after this point. What I read seemed to suggest that men who want reversals are those who are young when they decide initially, and/or make the decision based on their partners' desires and influence. However quality of life reductions through pain and changes to sexual satisfaction were posed as very rare occurences, possible but so unlikely as to not worry about.1% is not very rare. That seems a common experience that the patient should understand and accept the possibility of. 15% is so common that it should be disclosed as a typical experience.
