title: [Hypogonadism and intersexuality--genetic causes and cytogenetic diagnosis].
abstract: Hereditary types of hypogonadism and intersexuality are based on a chromosomal aberration, on a monogenetic defect of androgen synthesis, or on a androgen receptor. Cytogenetic diagnostic methods are suitable mainly for diagnosis of gonosomally caused syndromes. Monogenic defects have to be proved on the basis of the known karyotype by endocronologie techniques.
