What is the prevalence of detransition among adolescents who took puberty blockers in peer-reviewed studies?
Executive Summary
Peer‑reviewed studies report very low measured rates of detransition or regret among adolescents who began puberty blockers, typically around 1–2% in cohort studies but up to 4% for broader “regret” measures in at least one survey; however, these figures come with major caveats about definitions, follow‑up, and missing data. The literature’s big picture is a scarcity of large, long‑term, representative studies: the strongest cohort evidence shows nearly all adolescents who started blockers remained in gender‑affirming care over available follow‑up, while other peer‑reviewed and observational papers report wider ranges and emphasize methodological limits [1] [2] [3].
1. Why the headline numbers look small — large cohort studies that follow prescriptions and visits
The most frequently cited peer‑reviewed cohort evidence of adolescents who received puberty blockers shows very high continuation rates: a Dutch study of 720 adolescents found 98% still had active prescriptions at average follow‑up, implying about 2% no longer had prescriptions, but this does not equate directly to true detransition or regret because some discontinued for medical, social or surgical reasons [2]. A separate peer‑reviewed survey of 220 treated adolescents found 4.1% reported regret and 1.8% had stopped medical care, which researchers interpreted as ~1.8% detransition in that sample [1]. These figures are important but reflect narrow operational definitions, clinic populations, and limited follow‑up windows, so they should not be read as definitive lifelong rates. The measurement method — prescription records vs. self‑reported regret — drives much of the difference in reported prevalence [1] [2].
2. Why some studies and reviews report wider ranges — definitions and denominators matter
Critical reviews and investigative summaries emphasize that the published range for discontinuation or regret varies substantially because studies use different endpoints: “detransition,” “discontinuation of care,” and “regret” are not interchangeable. Reviews summarizing heterogeneous literature find discontinuation ranges from 1.9% up to nearly 30% in some small or poorly controlled series, and regret estimates from under 1% to around 13%, depending on how outcomes and follow‑up loss are handled [4] [3]. Journalistic investigations and critical reviews underscore that loss to follow‑up, exclusion of those who died, and clinic selection bias can undercount regret or detransition, while self‑selected detransitioner surveys can overstate rates if they lack denominators [3] [5]. The disparate methodologies create a wide, not contradictory, evidence landscape that requires careful interpretation.
3. What the peer‑reviewed record cannot tell us — key gaps and uncertainties
Available peer‑reviewed studies generally lack long‑term, population‑representative follow‑up covering the entire period from puberty blocker initiation through adulthood, so we cannot yet compute a definitive lifetime prevalence of detransition among adolescents treated with blockers. Studies often exclude individuals lost to follow‑up, fail to capture non‑prescription reasons for stopping care, and rarely provide standardized, validated measures of “regret” versus clinically appropriate discontinuation [6] [7]. Experts and reviews warn that placebo, evolving standards of care, changing patient populations, and limited follow‑up are important omitted considerations that constrain interpretation of the low percentages reported in cohort studies [6] [7]. These limitations matter for policy and clinical counseling because they affect how clinicians and families weigh risks and benefits.
4. Voices from detransitioners and methodological counterpoints — different data types, different stories
Qualitative and survey‑based research captures experiences that cohort prescription studies miss: cross‑sectional surveys of self‑identified detransitioners document diverse reasons for stopping transition‑related care, including social pressure, evolving identity, or adverse effects, but these studies lack denominators and cannot provide population prevalence [8] [5]. Investigative reporting and critiques urge caution about undercounting regret, noting some clinic‑based series likely miss dissatisfied patients lost to follow‑up and that self‑report samples highlight narratives and care gaps that cohorts do not [3] [5]. These contrasting data types are complementary: cohorts estimate rates within treated populations under clinical follow‑up, while detransitioner surveys reveal lived experiences and potential system failures that cohorts may underrepresent.
5. Bottom line for clinicians, policymakers, and the public — cautious interpretation with clear next steps
The peer‑reviewed evidence to date supports that measured detransition/regret among adolescents who started puberty blockers is low in the cohorts studied (roughly 1–2% for documented discontinuation; up to ~4% for self‑reported regret in one survey), but this conclusion must be qualified by important methodological gaps, variable outcome definitions, and short follow‑up making a definitive prevalence impossible. The evidence agenda is clear: standardized outcome definitions, longer and more representative follow‑up, transparent accounting of losses to follow‑up, and mixed methods that include detransitioner perspectives are required to resolve current uncertainty [1] [2] [3]. Policymakers and clinicians should use current figures as provisional clinical data, not immutable population truths, and communicate uncertainties to patients and families when discussing puberty blockers.
