cellular
• degeneration of preovulatory prophase I oocytes
• ovaries show high levels of apoptosis, not only within oocytes but also in surrounding granulosa cells
• early oogenesis arrest, with degeneration of preovulatory prophase I oocytes
• 8-week-old ovaries show oocytes in various stages of degeneration and cell death
• 5-week-old ovaries have oocytes that show initial signs of degeneration, with 35% of oocytes remaining in the living state and the remainder showing various abnormalities

endocrine/exocrine glands
• ovaries show high levels of apoptosis, not only within oocytes but also in surrounding granulosa cells
• the presence of corpora lutea (indicating previous ovulation) are not seen
• mature antral follicles ready for ovulation are not seen
• smaller ovaries with arrest of follicular growth at the early antral stage and no sighs of significant follicular growth
• ovarian follicle growth cannot be restored by hormonal stimulation with pregnant mates serum gonadotropin (PMSG) or human chorionic gonadotropin (hCG)
• smaller ovaries with no sighs of significant follicular growth or earlier ovulation
