title: Effects of progesterone and oestradiol-17beta on the spontaneous meiotic maturation of mouse oocytes.
abstract: 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.
