Efficiency of metaphase II oocytes following minimal/mild ovarian stimulation in vitro fertilization

Background An inverse relationship between oocyte efficiency and ovarian response was reported in conventional IVF. The purpose of this study was to report metaphase II (MII) oocyte efficiency according to oocyte yield in minimal/mild stimulation IVF (mIVF) and to assess whether oocyte yield affects live birth rate (LBR). Methods Infertile women (n = 264) aged 0.05). The number of MII oocytes had poor sensitivity and specificity for predicting a live birth. Conclusion These data extend the hypothesis of oocyte efficiency reported in conventional IVF protocols to mIVF protocols. Trial registration Registration clinicaltrials.gov: NCT00799929.
