Episode notes
Definitions Drive Detransition Rates
- Detransition definitions vary widely across studies, producing very different prevalence estimates.
- Kinnon MacKinnon's study defines detransition as identity shift plus stopping medical treatments, estimating 1–10% prevalence.
Two Equally Common Drivers
- Detransition reasons split roughly in half between internal and external causes.
- About half stop because their identity or health concerns change and half due to discrimination, lack of support, or finances.
