[Indications for the surgical intervention in endocrine disorders of the ovaries].

Endocrine disturbances of the ovaries with indication for surgery are rare. They require close cooperation between paediatric endocrinologist and paediatric surgeon. Clarification is mainly based on endocrinological findings and ultrasound examination of the ovaries. The following disturbances are discussed: Central (genuine and peripheral or pseudo-) precocious puberty, hormonally active ovarian tumours and cysts, the various forms of dysgenesis of the gonads, especially tumour-prone mixed gonadal dysgenesis with XO/XV karyotype, the syndromes of polycystic ovaries, and girls who grew up as boys with male external genitals.
