title: [Biophysical parameters of early puberty in girls].
abstract: OBJECTIVE
  The appearance of breast development in girls characterizes an early period of puberty. Ultrasonographic examinations of the uterus and ovaries make possible the estimation of first pubertal changes in sexual organs.
  
  
  METHODS
  The aim of this work was to study the clinical and ultrasonographical features of early puberty in girls.
  
  
  METHODS
  33 healthy girls were observed quarterly in the course of prepuberty. Body mass, height, body mass index (BMI), quantity of adipose tissue were investigated. Stage of puberty was established according to Tanner. The uterus and ovaries were studied ultrasonographically, and the volume of the uterine body, length of the cervix and ovarian volume and size of ovarian follicles were scrutinised.
  
  
  RESULTS
  Statistical differences were observed in weight, height, quantity of adipose tissue and the volume of body and that of the uterus, in length of the cervix between prepuberty and early puberty periods. Luminastity of mucus in the cervical canal in half of girls in the breast stage M1 was obtained.
  
  
  CONCLUSIONS
  Ultrasonographic investigations of internal sexual organs with estimation of clinical sexual features are helpful in examination of early stage of puberty.
