title: [Ovarian hyperandrogenism in adolescent girls with menstrual disorders].
abstract: OBJECTIVE
  In women with polycystic ovaries (PCO) hyperandrogenemia, an increased LH-concentration and a hightened ratio of LH/FSH are common. In adolescent hirsute girls with menstrual disorder, which may herald PCO in adulthood, ovarian hyperandrogenemia was under scrutiny. In most of them functional ovarian hyperandrogenism (FOH) is present in response to challenge with GnRH analog. It is not known whether FOH is involved in the pathogenesis of menstrual disorders in adolescent girls without hirsutism.
  
  
  METHODS
  24 girls with menstrual disorder in the mean age of 17.5 +/- 1.6 years old were investigated and compared to the age matched group of girls with regular menses. Basal and GnRH stimulated levels of ovarian androgens and gonadotropins were measured and USG of the ovaries were performed in all girls.
  
  
  RESULTS
  In over 50% of girls with menstrual disorder basal and stimulated 17 OH progesteron and androstenedione levels were found significantly higher as compared to the control groups. In all girls but three they were not associated with the polycystic structure of the ovaries. Only half of these girls had an increased LH/FSH ratio.
  
  
  CONCLUSIONS
  Functional ovarian hyperandrogenism may be present in adolescent girls with menstrual disorder in spite of the absence of the clinical signs of hirsutism and polycystic structure of the ovaries.
