Ovarian volume in premenarchal girls - a reference guide for routine pelvic ultrasonography.

OBJECTIVES

To provide reference values for ovarian volume in healthy premenarchal girls for use in routine pelvic ultrasonography interpretation.

MATERIAL AND

METHODS

A retrospective analysis of 170 healthy girls aged 0 to 11 years who underwent pelvic ultrasound examinations between 2015 and 2022 at a private gynecology clinic. Ovarian volumes were measured using transabdominal ultrasonography and calculated by the prolate ellipsoid formula. Mean ovarian volumes were analyzed by age groups.

RESULTS

The mean ovarian volume increased with age. A significant difference between right and left ovarian volume was not observed in most age groups. The data provides age-specific reference values that may aid in the clinical evaluation of ovarian development in premenarchal girls.

CONCLUSIONS

Our study confirmed that significant variations in ovarian volume occur across various stages of growth and puberty, making the accurate determination of abnormal values essential for proper diagnosis.
