title: [Casual analysis of menstrual disorders in adolescent girls].
abstract: OBJECTIVE
  Menstrual disorders are very common during the early postmenarcheal years. This study was undertaken to determine the causes of menstrual disorders in adolescents.
  
  
  METHODS
  In the research there were included 117 girls 14-18 years old without evidence of androgen excess (hirsutism, acne): the study group consisted of 87 adolescents with menstrual disorders and the control group of 30 girls with regular menstrual cycles. All the patients underwent gynecological and ultrasound examination and an analysis of the hormonal status.
  
  
  RESULTS
  The data from our investigation show that 43.7% of adolescents with menstrual dysfunction have eating disorders, 16.1%--immaturity of hypothalamic-pituitary-ovarian axis, 13.8%--polycystic ovary syndrome, 9.2%--hyperprolactinemia, 4.6%--delayed puberty, 3.4%--genetic defect and 9.2% other reasons.
  
  
  CONCLUSIONS
  A thorough history and physical examination focusing on the basic understanding of pubertal and menstrual physiology and pathology allows to obtain an accurate diagnosis. The prognosis for later fertility depends on the preventive measures token in adolescence.
