BackgroundDisorders of sex development (DSD) are congenital conditions characterized by atypical development of chromosomal, gonadal, and phenotypic sex. 46, XY DSD can result from disorders of testicular development or androgen synthesis.MethodsWe present 2 rare cases of 46, XY DSD, specifically XY pure gonadal dysgenesis and complete androgen insensitivity syndrome.ResultsBoth cases underwent prophylactic gonadectomy due to the elevated risk of gonadal malignancy. Bilateral gonadoblastoma and dysgerminoma were diagnosed on one side, while Leydig cell hyperplasia and only Sertoli cells were diagnosed in the seminiferous tubules on both sides. The normal menstruation for the pure gonadal dysgenesis patient only as CAIS patients never menstruate. Estrogen replacement therapy was administered periodically to promote the development of secondary sexual characteristics and menstruation in pure gonadal dysgenesis case, as well as to prevent osteoporosis. Follow-up examinations revealed no tumor recurrence, and the patient with Swyer syndrome had regular menstrual cycles.ConclusionLaparoscopic bilateral prophylactic gonadectomy and long-term hormone therapy with patient counseling and support are recommended.Copyright © 2024 the Author(s).
