ABSTRACT

This study was conducted to establish the normal values of ovarian volumes in this locality. A convenience sample of 141 apparently and gynecologically healthy and non pregnant females was studied using transabdominal sonography. The length, width and anteroposterior dimensions of both the right and left ovaries were measured. Volumes of the ovaries were determined using the prolate ellipsoid formula. The mean ovarian volumes were found to be a 9.5cm³ and 10.cm³ for the right and left ovaries respectively. A mean ovarian volume (Right and left) was 9.9cm³. A mean (right and left) range of 5.3cm³ to 13.9cm³ was also established. Significant correlations were noted between ovarian volumes and age (r=0.93, p<0.05) and between ovarian volumes and body weight (r=0.73, p<0.05). This study has established a nomogram for ovarian sizes in this locality which would offer a valid method of evaluating ovarian volumes in clinical practice.
