Sonographic incidence of polycystic ovaries in a gynecological population



The prevalence of polycystic ovaries in a large population of 1078 women of reproductive age was determined by pelvic ultrasonography. The ovarian ultrasonic appearance of 183 (17%) women met the morphological criteria of polycystic ovaries. Of these women, 147 (80.3%) had irregular cycles (group A) and 36 (19.70%) had normal cycles (group B). The remaining women constituted the control group. Ovarian volume was calculated in all women in whom at least one ovary was visualized. Serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH) and testosterone were measured in 124 women from group A, 25 from group B and 50 controls. Mean ovarian volume was statistically higher in both group A (13.4 ml) and group B (11.8 ml) than in the control group (6.2 ml). Mean LH/FSH ratio and mean testosterone values were statistically higher in group A only (2.1 and 1.1 ng/ml, respectively) compared with the mean values in the control group (0.7 and 0.7 ng/ml, respectively). Obesity and hirsutism were more common in group A than in group B and the controls.

Screening the ovaries in women of reproductive age and subsequent assessment of morphology in polycystic ovaries can aid in the diagnosis of this condition in patients who may have a varied clinical presentation. Copyright © 1995 International Society of Ultrasound in Obstetrics and Gynecology
