Prevalence of Polycystic Ovary Syndrome Phenotypes Using Updated Criteria for Polycystic Ovarian Morphology: An Assessment of Over 100 Consecutive Women Self-reporting Features of Polycystic Ovary Syndrome

“…A subset of participants evaluated in this study was used to develop revised sonographic criteria for polycystic ovarian morphology as described previously. 13 …”

Hormon anty-müllerowski i zespół policystycznych jajników

“…Ponadto, stosowanie aparatów ultrasonograficznych o wysokiej rozdzielczości umożliwia dokładniejszą ocenę puli pęcherzyków jajnikowych. Skłania to do zmiany kryterium liczby pęcherzyków jajnikowych z 12 (wg kryteriów rotterdamskich z 2003 r.) do 19 bądź 25 [4,51]. Lauritsen i wsp.…”

The New Three-dimensional Ultrasound Modes allow a Better Polycystic Ovary Syndrome Ultrasound Diagnosis beyond the Rotterdam Criteria

“…Early comparative studies showed intra and interobserver variations in the two-dimensional (2D) transvaginal AFC in the general population and a 12 to 13% rate of underestimation in the exact number of antral follicles present within the ovary, 11 however, recent studies, using new three-dimensional (3D) US modes, increase this underestimation rate up to 20 to 30%. [12][13][14][15][16][17]22 Besides this limitation, and in order to maintain standard criteria for research purposes, 2D transvaginal scan remains as the recommended method for antral follicle count in the general population including PCOS patients, and the count of at least 12 follicles remains the limit to categorize a polycystic appearance ovary. 6 Herein, we describe several and modern 3D ultrasound modes for the study of PCOS-related ovarian morphology; these new methods are scarcely mentioned on the medical literature since the clinical experience is limited; further, they are sometimes described as 'future techniques'.…”

“…16,17,21,22 Recent publications focused on PCOS patients showed a mean number of AFC of 19 to 26 follicles. 12,13,28 This situation has arisen from the marked improvements in the level of spatial resolution afforded by newer ultrasound scanners. Ovarian volume or area (OA) were also included as mandatory diagnostic criteria by ESHRE.…”
