Summary

Researchers at the Amsterdam clinic that pioneered the Dutch approach of blocking puberty linked the records of 720 young people who started puberty blockers and then cross-sex hormones as teenagers to the national prescription register. At the end of 2018, 98% still had a hormone prescription, and no medical factor predicted stopping. The authors called this reassuring. The figure is widely cited as proof that regret is rare, but it counts prescriptions, not satisfaction or wellbeing. Half the group was about 19 or younger at follow-up, detransition often happens years later, the reasons the 16 people stopped are unknown, and people whose ovaries or testes have been removed need hormones regardless. It shows most people stayed on treatment into early adulthood, not that regret is low.

Key findings

  • شملت الدراسة 720 شخصاً (69% وُلدوا إناثاً) بدؤوا حاصرات البلوغ قبل 18 ثم أضافوا الهرمونات المغايرة في عيادة أمستردام.
  • في نهاية 2018، كان لدى 704 (98%) وصفة هرمونات مغايرة في السجل الوطني؛ ولم يكن لدى 16 أي وصفة.
  • كان العمر المعتاد عند بدء الحاصرات 14 لمن وُلدوا ذكوراً و16 لمن وُلدن إناثاً؛ وعند المتابعة كان العمر المعتاد نحو 20 و19 فقط.
  • لم يتنبأ العمر وسنة الزيارة الأولى ومرحلة البلوغ والعمر عند بدء الهرمونات واستئصال المبايض أو الخصيتين بمن توقف عن الهرمونات.
  • عدّت الدراسة وصفة يدفع التأمين ثمنها، لا هل أُخذت الأدوية فعلاً، ولا الرفاهية أو الرضا أو الندم، وأسباب توقف الـ 16 مجهولة.
  • كان جميع من في الدراسة قد بدؤوا الهرمونات المغايرة، لذا لم يُحتسب المراهقون الذين توقفوا بعد الحاصرات وحدها.
  • وجدت دراسة لسجلات الصحة العسكرية الأمريكية (روبرتس وآخرون، 2022) أن نحو 30% توقفوا عن الهرمونات خلال أربع سنوات، مما يظهر أن النتائج تختلف بشدة بين الأماكن.

Abstract

BACKGROUND: In the Netherlands, treatment with puberty suppression is available to transgender adolescents younger than age 18 years. When gender dysphoria persists testosterone or oestradiol can be added as gender-affirming hormones in young people who go on to transition. We investigated the proportion of people who continued gender-affirming hormone treatment at follow-up after having started puberty suppression and gender-affirming hormone treatment in adolescence. METHODS: In this cohort study, we used data from the Amsterdam Cohort of Gender dysphoria (ACOG), which included people who visited the gender identity clinic of the Amsterdam UMC, location Vrije Universiteit Medisch Centrum, Netherlands, for gender dysphoria. People with disorders of sex development were not included in the ACOG. We included people who started medical treatment in adolescence with a gonadotropin-releasing hormone agonist (GnRHa) to suppress puberty before the age of 18 years and used GnRHa for a minimum duration of 3 months before addition of gender-affirming hormones. We linked this data to a nationwide prescription registry supplied by Statistics Netherlands (Centraal Bureau voor de Statistiek) to check for a prescription for gender-affirming hormones at follow-up. The main outcome of this study was a prescription for gender-affirming hormones at the end of data collection (Dec 31, 2018). Data were analysed using Cox regression to identify possible determinants associated with a higher risk of stopping gender-affirming hormone treatment. FINDINGS: 720 people were included, of whom 220 (31%) were assigned male at birth and 500 (69%) were assigned female at birth. At the start of GnRHa treatment, the median age was 14·1 (IQR 13·0-16·3) years for people assigned male at birth and 16·0 (14·1-16·9) years for people assigned female at birth. Median age at end of data collection was 20·2 (17·9-24·8) years for people assigned male at birth and 19·2 (17·8-22·0) years for those assigned female at birth. 704 (98%) people who had started gender-affirming medical treatment in adolescence continued to use gender-affirming hormones at follow-up. Age at first visit, year of first visit, age and puberty stage at start of GnRHa treatment, age at start of gender-affirming hormone treatment, year of start of gender-affirming hormone treatment, and gonadectomy were not associated with discontinuing gender-affirming hormones. INTERPRETATION: Most participants who started gender-affirming hormones in adolescence continued this treatment into adulthood. The continuation of treatment is reassuring considering the worries that people who started treatment in adolescence might discontinue gender-affirming treatment. FUNDING: None.

Conclusion

Most participants who started gender-affirming hormones in adolescence continued this treatment into adulthood. The authors consider the continuation of treatment reassuring given concerns that people who start treatment in adolescence might later discontinue it.
