About 6% of men who undergo vasectomy seek reversal or self-report
regret in long-term follow-up, according to a 2022 review of the urology
literature (PMC9476225). Individual study estimates range from 2.2%
(Galano et al. 2023, single-centre retrospective, n=274) to 7.4% (childless
men at telephone follow-up). Reversal-seeking almost certainly
underestimates true regret: the procedure costs $3,000-15,000 out of pocket
and success rates decline with time elapsed, meaning a man who regrets his
vasectomy at year 10 may not appear in reversal statistics. On the inaction
side, no published survey directly measures regret among men who chose not
to get a vasectomy. The 4% inaction proxy is constructed from the
contraceptive-burden literature: in a French survey of vasectomised men,
about three-quarters (76%) cited relieving their partner’s contraceptive
burden as the main motivation, suggesting that men who did not act may
carry latent awareness of the asymmetry — though this is a proximal
motivation measure, not a regret measure.
Age is the dominant moderator on the action side and accounts for most
of the clinical concern about vasectomy regret. Men vasectomised before
age 30 are approximately 12.5 times more likely to seek reversal than those
who wait until their 30s. The most common precipitant of regret across
studies is a change in partner — remarriage after divorce, or the death of
a child — rather than a change of mind about having children in a stable
relationship. This means the aggregate 6% rate masks a much higher rate
among young men who act before life circumstances have stabilised —
consistent with the 12.5-times-higher reversal-seeking rate cited above —
and a substantially lower rate among men in their 30s and 40s with
completed families.
The balanced classification reflects the overall population rather than
any particular subgroup. Gilovich and Medvec’s typical finding — inaction
regret dominates in the long run — is consistent with vasectomy as a
category: the option to act remains open at any time before the procedure
is taken, which dampens inaction regret. But the action side has measurable
regret with a known mechanism (age-related life-circumstance change), and
the inaction side lacks any direct measurement. Both rates carry
substantial uncertainty, and the delta (0.02) should be read as roughly
balanced, not as a precise quantitative claim.

Approximately 6% of men who have had a vasectomy seek reversal; key predictors include age <30, childless status, and change in relationship
Trecho
“"[Paraphrase from abstract -- full text paywalled] A review of the literature on vasectomy regret found that approximately 6% of men who undergo vasectomy seek reversal. Key factors influencing regret include age at the time of vasectomy, parental status, pre- and post-operative relationship status, unresolved physical and psychosexual problems, and development of chronic scrotal pain following the procedure. Men who elect vasectomy prior to age 30-35 are much more likely to regret the decision; one study found men who underwent vasectomy in their 20s are 12.5 times more likely to seek reversal."

PMC/Health Psychology Research narrative review (2022), PMC9476225. The ~6% reversal-seeking rate is the most commonly cited aggregate figure across the literature and is used as the action-side regret rate. Reversal-seeking underestimates true regret (many men who regret do not seek or cannot afford reversal), so the true regret rate may be higher, possibly 7-10%. The Galano et al. (2023) chart review of 274 patients found a lower 2.2% regret rate in a single- center sample, while the 2022 childless-men study found 7.4% present-day regret. The 6% is used as a representative midpoint.

Overall regret rate was 2.2% (6/274) in a retrospective chart review; primary reasons: change in partner (4), post-vasectomy pain (1), reconsideration of parenthood (1)

“"[Paraphrase from abstract -- full text paywalled] A retrospective chart review of 274 patients who underwent vasectomy at a single centre between 2014 and 2022, supplemented by semi-structured telephone interviews. The overall rate of regret was 2.2% (n=6). Primary reasons included a change in partner (n=4), post-vasectomy pain syndrome (n=1), and reconsideration of parenthood (n=1). Most men (90%+) reported being satisfied with their decision."

Galano et al. 2023, TAU. Single-centre retrospective study (n=274), so not representative of the general vasectomised population. The 2.2% figure is at the low end of published estimates and may reflect selection bias (patients at a specialist urology practice who received thorough pre-operative counselling). Used as a lower bound to anchor the 2-7% range; 6% is used as the primary rate.

“"A vasectomy is a surgical procedure performed as a method of birth control in men. It involves cutting the tubes (the vas deferens) that carry sperm from the testicles. Vasectomy is one of the most effective forms of birth control. Only about 15 of every 10,000 couples get pregnant in the year after the man has a vasectomy."

Cálculo
NICHD fact sheet used to contextualise the scale of vasectomy use and the contraceptive burden on couples. No direct inaction-regret figure is available. The 4% proxy is constructed as follows: men who do not get a vasectomy and rely on partner contraception or barrier methods sometimes experience unintended pregnancies or ongoing contraceptive burden that generates retrospective regret about not having acted. The 4% is below the action-side 6% on the assumption that the option remains open (inaction regret is dampened by the continued possibility of acting), and that most non-vasectomised men actively prefer non-permanent contraception. This is a placeholder proxy, not a survey finding -- see caveats.

Revisado por pares
The main motivation for vasectomy was the shift in contraceptive burden, reported by 76% of patients (survey of men undergoing vasectomy, n=446, 177 responders)
Trecho
“"The main motivation for vasectomy was the shift in contraceptive burden for 76% of patients. [...] 97% of men reported being satisfied with having undergone vasectomy; 96% had no regrets about surgery." This shows that relieving the partner's contraceptive burden is the dominant reason men elect the procedure, which supports the inaction proxy: men who do not act, and whose partners bear the full contraceptive burden, may carry ongoing awareness of that asymmetry -- a potential source of retrospective regret that is not directly measured.

Touil W, Delaunay B, Prudhomme T, et al. "Sexual and couple outcomes of vasectomy: Results of a French questionnaire survey." The French Journal of Urology 2024;34(9):102672. DOI 10.1016/j.fjurol.2024.102672. Consecutive series of 446 men undergoing vasectomy at a university centre (2010-2022); 177 responded to a 2022 online survey (median 33 months post-surgery). The 76% contraceptive-burden motivation figure is cited here to explain the construction of the inaction proxy: men who did not get vasectomies and whose partners bore the full contraceptive burden may retrospectively regret inaction, particularly after an unintended pregnancy or after their partner experienced serious side effects from hormonal contraception. The 4% figure is an editorial estimate, not a direct finding. (Replaces an earlier cite to PMC9476225 that attributed a "50.7% / 139 men" contraceptive-burden figure not present in that paper.)

Ressalvas
This entry is proxy_only on both sides. The action-side 6% is a literature-derived aggregate of reversal-seeking rates and self-reported regret from multiple studies; individual studies range from 2.2% (Galano 2023 single-centre) to 7.4% (childless men, telephone follow-up). Reversal- seeking underestimates true regret: many men who regret do not seek or cannot afford reversal surgery, which costs $3,000-15,000 and has declining success rates with time elapsed. The inaction-side 4% is a constructed placeholder proxy: no published large-sample survey directly asks non-vasectomised men whether they regret not having the procedure. The proxy is anchored slightly below the action side because inaction options remain open (a man can still act), which is the primary Gilovich mechanism for suppressing inaction regret. If anything, the true inaction-regret rate among men who experienced an unintended pregnancy or whose partner suffered serious contraceptive side effects is likely higher than 4%; the figure is deliberately conservative. Age is the dominant moderator on the action side: men vasectomised before age 30 are approximately 12.5 times more likely to seek reversal than those vasectomised at 30 or older. A separate entry specifically for young (<30) men seeking vasectomy would show a clear action_dominates pattern. The balanced classification here reflects the aggregate population, not the high-risk young-male subgroup. Data are predominantly from Western clinical populations; vasectomy uptake and regret patterns in countries with different contraceptive norms, family size expectations, or health system access may differ substantially.
