The spontaneous meiotic maturation of cumulus-free oocytes was not affected by progesterone or oestradiol-17beta at 2 microgram/ml, but both steroids decreased polar body production at 10 microgram/ml and progesterone decreased the number undergoing germinal vesicle breakdown.
裸卵的自发减数分裂成熟不受2微克/毫升孕酮或17β-雌二醇的影响,但两种类固醇在10微克/毫升时均会降低极体产生率,且孕酮会减少发生生发泡破裂的卵子数量。
