[Human follicular oocytes (cytologic and physiologic characteristics)].

The morphology and the rate of degenerative changes were studied in the oocytes recovered from the antral follicles of the operated women. The rate of meiosis resumption, chromosome aberrations and electrophysiological properties were studied in the cultivated oocytes. These indices were compared in women of different age and pathology. A small part of the whole population of follicular oocytes is capable to complete in vitro cytoplasmic and nuclear transformations indispensable for fertilization and further development. A conclusion is drawn that the heterogeneity of follicular oocytes reflects the regular processes of follicle growth and elimination in the ovary.
