In vitro fertilization and first cleavage rates. A In ‘FSH + hCG, MII group’ and ‘FSH-priming, MII group’ the fertilization rates were calculated from the number of in vivo matured oocytes. In ‘FSH + hCG, IVM group’ and ‘FSH-priming, IVM group’ the fertilization rates were calculated from the number of oocytes matured in vitro. B First cleavage rate calculated as the percent of 2-cell embryos from fertilized oocytes. Both MII groups refer to in vivo matured oocytes, while IVM group includes oocytes matured in vitro. The number of stimulations in each group is shown in square brackets. The number of stimulations in each group is shown in square brackets. The experiments during which no mature oocytes were obtained were not included in the respective groups. * p < 0.05, ** p < 0.01, *** p < 0.001
