A 2024 study in the Journal of Pediatric Urology administered the validated Decision Regret Scale to parents of both circumcised and uncircumcised boys at a US outpatient urology clinic. The result was a rare null finding: 21% of parents in each group reported moderate-to- strong regret. Both groups had a median regret score of 0, and the authors found no difference in median scores between them; pooled across both arms, scores were positively skewed with a mean of 22 and ranged from 0 to 75. Whichever choice a parent made, about one in five second-guessed it.

This symmetry is unusual in the regret literature, where most decisions show at least a modest tilt toward one side. The circumcision debate is culturally and politically charged, with strong advocacy on both sides claiming the other path leads to regret. The data suggests neither side has the stronger empirical claim. A companion study in Frontiers in Pediatrics found that even among parents who went so far as to pursue circumcision revision, 27.5% reported any decisional regret and only about 5% (2 of 40) reported moderate-to-strong regret — the procedure does not appear to generate outsized decisional distress.

The major caveat is the study population. Parents presenting at a pediatric urology clinic are not a general-population sample — they are there because something prompted a visit, which likely inflates concern and regret in both groups. The absolute 21% figure may overstate regret among all parents. More fundamentally, the DRS captures parental regret, not the preferences of the person whose body was modified. Adult men circumcised as infants may hold views that diverge from what their parents report, and that data is sparse.

    Parent decisional regret regarding neonatal circumcision in an American outpatient pediatric urology clinic
    Statistic
    21% of parents of circumcised boys scored moderate-to-strong regret (DRS 30-100); median DRS was 0, mean was 22
    Excerpt
    “"One in five parents of both circumcised and uncircumcised boys expressed moderate to strong regret regarding their decision about neonatal circumcision in our pediatric urology clinic. Overall, 55% of both groups reported no regret (DRS = 0), 24% had low-mild regret (DRS 5-25), and 21% yielded moderate-strong regret (DRS 30-100)." ”

    Calculation
    The Decision Regret Scale (DRS) was administered to parents at a pediatric urology outpatient clinic (91 circumcised, 28 uncircumcised; 119 total). 21% scored moderate-to-strong regret in the circumcised group (n=91). We use 0.21 as regret_rate. Note: clinic population may overrepresent parents with concerns.

    Parent decisional regret regarding neonatal circumcision in an American outpatient pediatric urology clinic
    Statistic
    21% of parents of uncircumcised boys also scored moderate-to-strong regret (DRS 30-100); both groups had a median DRS of 0, and there was no difference in median regret scores between them
    Excerpt
    “"One in five parents of both circumcised and uncircumcised boys expressed moderate to strong regret regarding their decision about neonatal circumcision.

    Calculation
    Same study, same instrument, same clinic population. The uncircumcised parent group (n=28) showed the identical 21% moderate-to-strong regret rate. The null finding — no difference between the two decision arms — is itself remarkable, though the small inaction-side sample limits precision.
  2. [2] Frontiers in Pediatrics / Bar-Yaakov et al. — Parental Regret Following Decision to Revise Circumcision
    Parental Regret Following Decision to Revise Circumcision
    Statistic
    Among parents whose sons underwent revision of a neonatal circumcision, 27.5% (11/40) reported decisional regret on the DRS — nine mild (23%) and two moderate-to-strong (5%); mean DRS 7.98 in the regret group
    Excerpt
    “"Parental decisional regret according to the DRS was reported in 11 cases (28%). Decisional regret as reflected by the DRS questionnaire was reported by 27.5% of parents of children who underwent revision of neonatal circumcision for excess foreskin. No clinical, surgical, or demographic characteristics predicted parental decisional regret." ”

    Calculation
    This study measured regret among parents who chose to revise a prior circumcision (n=40 surveyed). Most reported regret was mild (9/40, 23%); only 2/40 (5%) was moderate-to-strong. That even a corrective second procedure produces mostly mild regret is consistent with the main study's finding that circumcision decisions do not generate outsized regret in either direction.

Caveats

The study population was drawn from a pediatric urology outpatient clinic, which likely overrepresents parents who have concerns about their child's penile health — a selection bias that could inflate regret in both directions. The identical 21% figure across both groups is the finding, but the absolute level may be higher than in a general population sample. The uncircumcised group is notably small (n=28 vs 91 circumcised), so the inaction-side regret rate carries wide confidence intervals and should be interpreted with caution. The DRS measures parental regret, not the child's future preferences — adult men circumcised as infants may have different views. Cultural, religious, and regional norms heavily influence circumcision rates (58% of US newborns are circumcised vs <10% in most of Europe), which limits cross-cultural generalizability.
