OBJECTIVE: To derive norms for the size of uterus, uterine shape (fundal-cervical ratio) and ovarian volume in girls in various Tanners stages of puberty. METHODS: Pelvic ultrasound was performed in ninety-two healthy girls in the age group of 8-15 years. These included twenty girls each in Tanner stages 1-4 and twelve in stage 5. All the subjects enrolled in the study had a weight and height within 5th-95th percentile of NCHS standards and their bone ages corresponded to the chronological age. Uterine height, fundal-cervical ratio (FCR) and ovarian volume were measured in all the subjects. The data was stratified according to various pubertal stages as well as for different ages. Statistical analysis was carried out to derive the percentiles for the three parameters in different pubertal stages and to study the correlation between these parameters and age, weight and height of the subjects. RESULTS: A statistically significant increase in uterine height, FCR and ovarian volume was observed with progressive pubertal stages. Maximum increase in uterine height was observed during the transition from stage 2 to stage 3. All girls beyond the age of 10 years or beyond Tanner stage 2 had a FCR>1. The ovarian volume, after showing an initial increase, tended to plateau and there was no significant increase from stage 4-stage 5. A significant correlation was found between the three parameters and the subject's age, weight and height, the maximum correlation was with age (correlation coefficients being 0.748, 0.648, 0.568 for uterine height, FCR and ovarian volume respectively). Centiles for these parameters were obtained for different pubertal stages. CONCLUSION: This work has provided some guidelines for normative data for various pubertal stages as well as for ages between 8-15 years. These may be used as a reference in evaluation of patients with suspected disorders of puberty.
