Forensic Medicine · Identification: ovotesticular disorder of sex development

Sample item

Gonadal biopsy in a patient with ambiguous genitalia shows ovarian tissue with follicles in one part and testicular tissue with seminiferous tubules in another. What is the diagnosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. True hermaphroditism (ovotesticular DSD)

In true hermaphroditism both ovarian and testicular tissue are present in the same individual, in one gonad (ovotestis) or in separate gonads. In pseudohermaphroditism the gonads are of one sex only but the external genitalia do not match.

Option by option

  • A. Female pseudohermaphroditism

    Female pseudohermaphroditism has ovaries only with virilised external genitalia.

  • B. Male pseudohermaphroditism

    Male pseudohermaphroditism has testes only with under-masculinised genitalia.

  • C. Klinefelter syndrome

    Klinefelter syndrome has small testes and an XXY karyotype without ovarian tissue.

  • D. True hermaphroditism (ovotesticular DSD) (correct)

    Correct. Both gonadal tissues in one person define it.
