The Aim: To assess the usefulness of ultrasound in the diagnostic strategy of anovulation and polycystic ovary through observation and recording of the size of the ovary, follicular development and any associated anomalies in the anovular cases in comparison with laparoscopy.Methods: Transvaginal ultrasound and laparoscopy were performed to the selected 37 inpatients.Results: From the previous data, an increase of ovarian size is a sign of PCOD. Ovarian size was estimated by calculating the cross sectional area and the roundness index. Diagnosis of PCOD by laparoscopy is based on the presence of three criteria or two criteria at least which are enlarged ovaries with smooth surface and the pearly white colour of the ovaries due to thickened tunica albuginea.Conclusion: Ultrasound can predict the presence or absence of polycystic ovaries almost as accurately as laparoscopy. The noninvasive natures of ultrasound makes repeat scans and follow up of ovarian response to therapeutic measure possible. Laparoscopy is found to be an important step to confirm the diagnosis of PCOD done by ultrasound and it might diagnose some overlooked cases.
