title: On fragmentation and elimination of ovarian oocytes.
abstract: Examination of numerous fragmented oocytes in the ovary revealed an asynchronous relationship between nuclear and cell divisions. The asynchrony was observed in non-fragmented oocytes as well and was considered to be one of the common processes leading towards oocyte elimination of the ovary. The present study additionally demonstrates the morphology of follicle cell degeneration observed on the surface of fragmented oocytes.
