Abstract
Fully mature oocytes are the rarest cells in the body. A premenopausal woman produces only one during each menstrual cycle and that survives for just a single day. Ovarian productivity is parsimonious in order that the ovulation rate matches the optimal capacity of the uterus for carrying conceptuses to full-term. But, in this new era of assisted reproductive medicine, there are many applications for which spare oocytes are needed (Table 1), and it is desirable to obtain more cells than are routinely available during superstimulated cycles. Since the great majority of ovarian oocytes undergo atresia (> 99.9%), the possibility of tapping the store of immature oocytes before they degenerate and maturing themin vitrois very attractive.
