Abstract
SUMMARY: The population of oocytes in the ovaries of the rat decreases slowly and continuously throughout middle and old age. The proportion of oocytes diagnosed as 'atretic' declines as the total number of oocytes diminishes. Reproductive capacity declines before the 'stock' of oocytes is exhausted.Keywords
