Background The aim of this study was to document the reproducibility of endometrial volume measurements by 3D‐ultrasound and VOCAL TM . Materials and methods One three‐dimensional endometrial measurement was performed on each 79 consecutive infertile patients undergoing IVF. All scans were obtained using the Voluson 530 D (Kretztechnik AG, Zipf, Austria) the day of the oocytes retrieval and stored on a 540 Mbyte with an integrated magneto optical drive. After B mode analysis of the endometrium the system was switched into volume mode. Endometrial volume was calculated with the VOCAL TM software. Volume was calculated by two different observers ( O1 and O2 ) and every 15° and 30° in order to appreciate inter and intra observer reliability. Results Mean endometrial volume was 4.00 cm 3 for each observer. Intra observer reproducibility was better for volume calculated at 15° (0.9754 for O1 and 0.9683 for O2 ) than volume calculated at 30° (0.9303 for O1 and 0.9602 for O2 ). A paired t ‐test showed that there was no statistical difference between the two observers for volume calculated each 15° and significant difference for volume calculated each 30°. Conclusion VOCAL permitted an easy and reproducible inter and intra observer calculation of endometrial volume during controlled ovarian stimulation for IVF.
