Summary

Researchers in Uppsala used Swedish national records to follow everyone first diagnosed with gender dysphoria between 2013 and 2023, 7,293 people. They checked who changed legal gender and who changed back. About a third (2,467) made a legal change. Only 21 changed back, so the estimated chance of keeping the new legal gender for 10 years was about 98%. The records are complete, but narrow. In Sweden, changing back needs a new application and a psychological assessment, so it is only a small, formal part of detransition. People who stop hormones, regret surgery or re-identify with their birth sex without changing their papers are not counted. Most people were followed for only a few years after their legal change, while detransition often happens 5 to 10 years after transition. The study shows that changing legal gender back is rare; it does not show that detransition is rare.

Key findings

  • Η μελέτη κάλυψε και τα 7.293 άτομα στη Σουηδία που διαγνώστηκαν για πρώτη φορά με δυσφορία φύλου μεταξύ 2013 και 2023 (4.083 γεννημένες γυναίκες και 3.210 γεννημένοι άνδρες), με παρακολούθηση περίπου 5 χρόνων το καθένα κατά μέσο όρο.
  • 2.467 άτομα (34%) άλλαξαν νομικό φύλο, κατά μέσο όρο 3,2 χρόνια μετά την πρώτη διάγνωση· η εκτιμώμενη πιθανότητα να το κάνουν μέσα σε 10 χρόνια ήταν 58%.
  • Μόνο 21 άτομα άλλαξαν νομικό φύλο πίσω στο φύλο γέννησής τους: 0,9% όσων είχαν αλλάξει και 0,3% ολόκληρης της ομάδας.
  • Η εκτιμώμενη πιθανότητα διατήρησης του νέου νομικού φύλου για 10 χρόνια ήταν περίπου 98% (πιθανώς μεταξύ 96% και 99%), χωρίς διαφορά μεταξύ ατόμων που γεννήθηκαν γυναίκες και ατόμων που γεννήθηκαν άνδρες.
  • Τα 21 άτομα που άλλαξαν πίσω ήταν παρόμοια με όλους τους άλλους· μόνο 2 είχαν διαγνωστεί πριν από την ηλικία των 18 και ήταν κατά μέσο όρο περίπου 30 ετών όταν άλλαξαν πίσω.
  • Οι συγγραφείς τονίζουν ότι η αλλαγή του νομικού φύλου πίσω δεν είναι το ίδιο με την αποχώρηση από την αλλαγή φύλου, δεν λέει τίποτα για λόγους ή ταυτότητα και πρέπει να αντιμετωπίζεται ως ελάχιστο.
  • Η συζήτηση της εργασίας δίνει το ποσοστό αναστροφής ως 0,09% όσων είχαν νομική αλλαγή, που είναι δέκα φορές χαμηλότερο από το 0,9% (21 από 2.467) στα δικά της αποτελέσματα.

Abstract

IMPORTANCE: The number of people seeking treatment for gender dysphoria (GD) has risen in recent decades, yet data remain limited for understanding cases of detransition (ie, the reversal of social, medical, or legal transition). Legal gender change in national registers poses an opportunity to examine legal gender reversals, which may reflect an aspect of the detransition process, while also informing an understanding of the stability after a legal gender change. OBJECTIVE: To determine the probability of obtaining a legal gender change and its stability over time among people diagnosed with GD in Sweden during a 10-year study period. DESIGN, SETTING, AND PARTICIPANTS: In this population cohort study using data from Swedish national registers from January 1, 2013, to December 31, 2023, individuals who received their first International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10), diagnosis code for GD during the study period were included. While participants may have received a GD ICD-10 code as youths, legal gender changes only occurred for adults (aged ≥18 years) based on legal requirements during the time of data collection. EXPOSURE: Gender dysphoria. MAIN OUTCOMES AND MEASURES: Legal gender change and its stability, that is, absence of legal gender reversal, as reported in the registry. Kaplan-Meier survival analysis was used to determine the probability of legal gender change and its stability during a 10-year study period. RESULTS: A total of 7293 people with a GD diagnosis were included (36 025 person-years). Approximately one-third of the sample (n = 2467) obtained a legal gender change during the study period. The probability of legal gender change at 10 years following diagnosis was 58.3% (95% CI, 56.2%-60.4%). Twenty-one cases of legal gender reversal were identified. The probability of legal gender stability at 10 years following the initial change was 97.7% (95% CI, 96.3%-99.2%), with no differences by sex assigned at birth for either outcome. CONCLUSIONS AND RELEVANCE: In this cohort study using national population registry data, a significant proportion of participants with GD in Sweden obtained legal gender change within 10 years of follow-up. Despite significant growth of the population with GD, the probability of legal gender stability during the 10-year study period was high, at almost 98%. These results highlight that legal gender reversal was an infrequent occurrence in a national sample.

Conclusion

In this cohort study using national population registry data, a significant proportion of participants with gender dysphoria in Sweden obtained legal gender change within 10 years of follow-up. Despite significant growth of the population with gender dysphoria, the probability of legal gender stability during the 10-year study period was high, at almost 98%, and legal gender reversal was an infrequent occurrence in a national sample. No differences by sex assigned at birth were observed, and most individuals who legally reverted were in their twenties at first diagnosis. The authors note that legal gender reversal is not synonymous with detransition, should be considered a lower-bound approximation, and cannot be generalized to social or medical detransition.
