Uterine and ovarian parameters in healthy North Indian girls from 5 to 16 years by ultrasonography.

INTRODUCTION

Knowledge of uterine and ovarian growth patterns during early age and puberty helps in investigating disorders of pubertal development i.e. precocious puberty, premature thelarche, or pubarche. There is a paucity of data for uterine and ovarian parameters. Aim of the study: The aim of this study is to present normative data for Uterine length, Mean ovarian volume (MOV), and fundo cervical ratio (FCR) from 5 to 16 years in healthy girls from north India and to correlate these parameters with age, weight, height, and pubertal Tanner staging.

MATERIAL AND

METHODS

A cross-sectional observational study was performed on 130 healthy girls age 5 to 16 years. Age, anthropometric parameters were measured and the pubertal stage was categorized using Tanner staging. All subjects underwent pelvic ultrasonography for the measurement of uterine and ovarian parameters.

RESULTS

Normative data of uterine length, MOV, and FCR were presented as mean, SD, median, and 95% confidence interval as per age and Tanner stage. A progressive increase in uterine length, MOV & FCR was observed with increasing age, weight, height, and Tanner stage (p < 0.001). A sudden significant increment in uterine length and MOV was observed between the age of 11-12 and 12-13 years (p < 0.001). Uterine length of < 4 cm, MOV < 2 cm3 and FCR < 1 were specific to identify pre-pubertal girls.

CONCLUSIONS

Normative data of uterine and ovarian parameters generated in our study by ultrasonography would be useful for screening girls with abnormalities of pubertal development.
