Introduction: In cases of disorder of sex development (DSD), the change between the gender assigned at birth and the individual's chosen gender identity can occur especially after puberty.
Aim: was to determine the relationship between genetic sex, gender assigned at birth and gender identity, and the importance of molecular diagnosis.
Method:154patients older than 14years of age, who were followed up with the diagnosis of DSD from 1983 to 2023 were included.
Results: The mean age at admission was 7.7years ± 6.4. Sixty three (41%) patients had 46,XXDSD and 75 (48.7%) patients had 46,XYDSD. Sex chromosomeDSD was identified in 16 (10.3%) patients. Of the 46,XX cases, 2 (9.5%) of 6 cases reared as male chose female gender identity during follow-up. With 46,XY cases, female gender identity was maintained in 28 of 36 (48%) cases who were raised as female, female-to-male gender transition occurred in7 (19.5%) cases and 1 case was uncertain. One of the 7 (43.7%) patients with sex chromosome DSD and assigned male gender identity preferred female gender identity (table1).

Conclusion: Gender determination is always a complex, challenging experience for clinicians. Gender reassignment management should be individualized in collaboration with a multidisciplinary team to preserve gonadal function, avoid irreversible surgeries, and align gender identity with the assigned gender.
