Disorder of Sex Development: A Case of Late-Diagnosed Ovotestis and Its Postsurgical Follow-up

True hermaphroditism is characterized by the presence of both testicular and ovarian tissue. This case report aimed to describe a case of ovotestis in adolescents. A 17-year-old patient presented with undifferentiated genitalia. Thelarche occurred at age 14, menarche occurred at age 15, and menstruation was regular. Physical examination showed female phenotype, Tanner IV breasts, gynecoid hair, enlarged clitoris, and labia majora symphysis with a single orifice. The patient presented high levels of total testosterone. The left gonad contained typical ovarian tissue and the right gonad contained both seminiferous tubules and ovarian tissue (ovotestis). Vaginoscopy revealed a single orifice (urethra and vagina). Right gonadectomy confirmed the presence of ovotestis. Knowledge of true hermaphroditism is important for early diagnosis and proper management.
