Transvaginal ultrasonography has been found to be very useful in gynaecological practice especially for its image clarity in assessing the ovaries and other pelvic organs. Its superiority to transabdominal sonography in assessing ovaries and monitoring follicles in invitro-fertilization (IVF) is not in doubt. The aim of this study is to establish normal values for ovarian volume in this environment using transvaginal technique. This was a prospective study carried out from June 2009 to February 2010. The volumes of right and left ovaries of 50 non pregnant female patients between the ages of 18 and 43 years who had transvaginal scan at the center were documented. None of the patients was on ovarian induction. And anyone with ovarian pathology was not recruited in the study. Results of this study suggest that mean ovarian volume in this environment is 9.7 and 10.2 cm3 for the right and left ovaries, respectively with combined mean of 9.8 cm3 . Transvaginal examination of the ovaries remains the better option in assessing the ovaries and monitoring ovarian size because of its better image quality and resolution.
