This study aims to investigate the difference in the number of oocytes obtained by performing ovarian stimulation in follicular phase vs. luteal phase in a population of patients with previous suboptimal response. This is a controlled randomized clinical study. We aim to include 41 patients diagnosed with suboptimal response who will undergo an ovarian stimulation in order to vitrify and accumulate oocytes. The main variable for evaluating the efficacy in this exploratory study will be the number of oocyte cumulus complexes obtained.
