Reproducibility of Endometrial Volume by VOCAL in the Prediction of Success Rate of IVF/ICSI in Women with Unexplained Infertility

Objective: To explore the role of estimating endometrial volume by Virtual Organ Computer-aided Analysis (VOCAL) and it's correlation with endometrial thickness, on the day of hCG, in prediction of IVF/ICSI success. Patients and Methods: It was a prospective study that was carried out at Al-Amin Maternity Hospital, Saudi Arabia. Endometrial thickness and volume were measured in women undergoing an IVF/ICSI cycle, on the day of HCG, using the 3D trans vaginal ultrasound probe. Women were divided as regards to endometrial volume calculated into 3 subgroups; < 3 ml, 3-5 ml, and >5 ml, also according to endometrial thickness into 3 groups; <7 mm, 7-12 mm and >12 mm. Success rate of IVF/ICSI was compared between all groups.
