Abstract: Purpose: We aim to estimate the future fertility of patient undergoing their first IVF cycle attempt with no oocyte retrieved, and to identify factors that might predict those who will conceive in subsequent IVF cycle attempt. Methods: A cohort retrospective study of all consecutive women attending our IVF unit, for their first IVF cycle attempt, between January 2013 to December 2019, who reached the ovum pick-up (OPU) stage with zero oocyte retrieved. Patients’ characteristics and infertility-treatment-related variables in the first IVF cycle attempt were compared between those who conceived in a subsequent cycle and those who did not. Moreover, infertility-treatment-related variables during successful cycles resulting in pregnancy were compared to those without. Results: 59 met the study inclusion criteria, yielding zero oocytes. During the follow-up period, 12 (20.3%) women conceived (one conceived twice), and 8 (14%) gave birth to a live infant. Cumulative live-birth rate per OPU and per patients were 4% and 14%, respectively. Clinical pregnancies were achieved after 3.61+1.4 cycle attempts (range: 1–6), with no live-births following the fifth IVF cycle attempt. No in-between group differences were observed in ovarian stimulation variables of their first IVF cycle attempt. Moreover, in those cycles resulting in pregnancy, patients achieved a significantly higher number of fertilized oocytes (2.15+1.5 vs 0.94+1.5, respectively; p
