Summary

Doctors at a large US children's gender clinic reviewed records of 1,050 teens who had taken cross-sex hormones for at least six months. At their most recent contact, 93% were recorded as still taking hormones, 2% had paused and restarted, and 4% had stopped. Only five people (0.5%) stopped because they again identified with their birth sex. Others mostly stopped because they had reached the body changes they wanted, or had trouble getting or taking hormones. The authors conclude stopping is rare and should not be assumed to mean regret or detransition. But the figures only show short-term use of hormones in one clinic's records. About 1 in 5 patients had not been heard from for over a year, yet were counted as still on hormones. Average follow-up was under three years. And people who detransition often do not tell their original clinic.

Key findings

Trong 1.224 thiếu niên bắt đầu dùng hormone tại Bệnh viện Nhi Boston từ tháng 1 năm 2007 đến tháng 12 năm 2022, 1.050 người được đưa vào vì có chẩn đoán phiền muộn giới và dùng hormone ít nhất sáu tháng liên tục.
Tại lần liên lạc cuối cùng, 973 người (93%) được ghi nhận vẫn đang dùng hormone, 20 người (2%) đã ngừng hơn ba tháng và bắt đầu lại, và 37 người (4%) đã ngừng mà không bắt đầu lại.
Năm người (0,5%) ngừng vì họ lại nhận mình theo giới tính khi sinh; các tác giả mô tả đây là dưới 1%.
Trong 37 người ngừng, 14 người cho biết họ đã đạt được những thay đổi cơ thể mong muốn; khó khăn trong việc tiếp cận hoặc duy trì hormone là các lý do chính khác, theo các tác giả và một bài xã luận đăng cùng.
210 trong 973 người được tính là vẫn đang dùng hormone đã không có tin tức trong hơn một năm, không có ghi nhận chuyển sang bác sĩ khác (tuổi điển hình của họ ở lần khám cuối khoảng 20).
Thời gian theo dõi ngắn: bài xã luận cho biết kết quả được đo trung bình khoảng 2,7 năm sau khi bắt đầu dùng hormone.
Các tác giả khuyến nghị nghiên cứu trong tương lai nên hỏi tại sao mọi người ngừng, thay vì cho rằng đó là chuyển giới trở lại hay hối hận.

Abstract

Purpose: To understand the rate of, and reasons for, discontinuation of gender-affirming hormones (GAH) in transgender adolescents.

Methods: Retrospective cohort study of individuals starting GAH between January 2007 and December 2022. Individuals were included if they were diagnosed with gender dysphoria, were prescribed GAH, and took GAH continuously for a minimum of 6 months. Of 1,224 individuals who started GAH, 1,050 met the eligibility criteria for this analysis. The primary study outcome was the status of GAH use at last communication. We also assessed gender identity at the time of GAH discontinuation and reasons for discontinuation among individuals who discontinued GAH for periods of 3 months or longer.

Results: Of 1,050 eligible individuals, 973 (93%) had been on GAH continuously at last contact, 20 (2%) had discontinued GAH for greater than 3 months then restarted hormones, and 37 (4%) had discontinued GAH without restarting hormones. Of those who discontinued hormones without restarting, 5 (0.5%) individuals did so because they reidentified with the gender associated with their sex assigned at birth. This represents less than 1 percent of the cohort.

Conclusions: In a large cohort of transgender adolescents seeking GAH, persistent discontinuation of hormones was rare and primarily reflected having accomplished gender expression goals or difficulties accessing or taking hormones - rather than individuals reaffirming a gender identity associated with their assigned sex at birth. It is important for future research on individuals who discontinue GAH to evaluate the reasons for discontinuation and not to make assumptions about detransition and/or regret.

Methodological limitations

Many lost from view but counted as still on hormones: 210 of the 973 reported as still on hormones (20% of the group) had not been heard from for more than a year. Whether they still take hormones, or how they identify, is unknown. So 93% is the highest the true figure could be.
Short follow-up: Average follow-up was about 2.7 years (Olson, 2025 editorial). In published surveys, detransitioners say they identified as trans for several years before stopping (5.4 years on average in Littman et al., 2024). So later stopping is likely missed.
One clinic's records only: Stopping and reasons came from one hospital's files. People who stop often do not tell their doctor (only 27% of detransitioners in Littman et al., 2024 told their clinician). Those who moved, aged out, or switched to adult or private care may not show up.
Measures hormone use, not wellbeing or regret: The study only checked whether hormones continued. It did not measure mental health, satisfaction, regret or identity. Staying on hormones does not by itself show benefit.
Early stoppers left out: Requiring six months of continuous use excluded 174 of 1,224 who started, including anyone who stopped early. This makes the stopping rate look lower.
Short breaks not counted: Only stops of three months or longer counted. Shorter breaks, irregular use and lower doses were not captured.
Reasons taken from doctors' notes: Why people stopped, and how they identified, came from clinical notes. These depend on what patients chose to tell doctors and how it was written down. No one was formally interviewed.
May not apply elsewhere: Patients were treated at a large, well-funded university clinic with assessment by several specialists. Results may not apply to other clinics, clinics that prescribe on request, or other countries.
Long, changing time span: Starts run from 2007 to 2022, when the kinds of patients and clinic practice changed a lot. The summary does not report results separately by period.
Clinic judging its own care: All authors work in Boston Children's Hospital departments (hormones, gynaecology, psychiatry) that provide this treatment. The clinic is reporting on its own care, with no independent check.
