Serial ultrasound (US) examinations are performed to assess the number and size of follicles during controlled ovarian stimulation (COS). Ovarian folliculometry during COS is the most frequent ultrasound procedure daily performed, an also a highly time consuming and reiterative process. However, it has been shown that manual measurement of follicles with 2D US is often inaccurate and subject to significant intra- and interobserver variability In addition, a follicle is a three-dimensional (3D) structure and its volume is the most accurate measure of its size. Therefore, 3D transvaginal ultrasound in gynaecology and reproductive medicine has supposed a great advance, because it makes possible to obtain ovarian volumes during controlled ovarian stimulation
