Morphological features measured by polarized light microscopy (PLM) on the oocytes of the three groups of expected poor responders (ePR), expected normal responders (eNR), and expected high responders (eHR). In all groups, n refers to the number of analyzed oocytes; there was no significant difference between patients receiving CFα day 2 or CFα day 4 regimen for all measured variables
