The ultrastructure of oocytes from large follicles and the meiotic maturation rate of preovulatory oocytes of intact and androgenized rats were studied. The oocytes of defeminized animals were characterized by the lack of organelles and by changes of their structure. According to the rate of meiosis they were divided into two groups. The one entered the II stage metaphase earlier than in the control, the other was characterized by a slower chromosome transformation.
研究了大卵泡卵母细胞的超微结构以及完整和雄激素化大鼠排卵前卵母细胞的减数分裂成熟率。去雌性化动物的卵母细胞表现为细胞器缺乏及其结构变化。根据减数分裂速率，它们被分为两组。一组比对照组更早进入减数第二次分裂中期，另一组的特征是染色体转化较慢。
