Sonographic Quantification of Ovarian Volumes in an Adult Nigeria Population

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; p0.05) and between ovarian volumes and body weight (r
