In vivo developmental potentials of in vivo and in vitro matured oocytes fertilized in vitro were assessed in cattle. One-cell stages produced from in vivo matured oocytes developed into a pregnancy when transferred to the ampulla part of oviducts of synchronized heifers. In vitro matured oocytes achieved high penetration and cleavage rates but did not develop into pregnancies when transferred to synchronized heifers.
对牛体内成熟和体外成熟的卵母细胞体外受精后的体内发育潜能进行了评估。由体内成熟卵母细胞产生的单细胞阶段胚胎，转移到同期发情小母牛输卵管壶腹部后可发育成妊娠。体外成熟的卵母细胞体外受精后有较高的穿透率和卵裂率，但转移到同期发情小母牛体内后未发育成妊娠。
