PELVIC ULTRASOUND MEASUREMENTS IN NORMAL GIRLS - RELATION TO PUBERTY AND SEX-HORMONE CONCENTRATION

Pelvic ultrasonography was performed on 75 normal girls. Values were o btained for uterine length, fundal/cervical ratio (FCR), ovarian volum e and sex hormones. The resultant data were grouped according to age a nd pubertal stage (Tanner), For uterine length, FCR and ovarian volume , the data were positively skewed, and the variance increased with age and pubertal stage (p<0.001). The uterus underwent a regular increase in size and the corpus gradually became larger than the cervix, Uteri ne length, right ovary volume, FCR and hormones (serum estradiol, foll icle-stimulating hormone and luteinizing hormone) showed a correlation with the Tanner score (p<0.001), Although the correlations were signi ficant, the best correlation was between pubertal stage and serum estr adiol level.
