Footnotes: aTotals are not 100 percent due to some patients having more than one diagnosis. bTotals are not 100 percent due to some patients undergoing more than one controlled ovarian stimulation/oocyte-pickup cycle. Abbreviations: RIF: repeated implantation failure; SD: standard deviation; GnRH: gonadotropin-releasing hormone.
