reproductive system
• males produce, on average, fewer total germ cells but accumulate more ES in the lumen of seminiferous tubules
• male germ cells grown in culture exhibit higher mortality than wild-type germ cells
• high rate of head or DNA material loss in sperm isolated from the epididymis
• germ cell progression through meiosis is hindered
• germ cell content at 3, 4, 7, 10, and 15 weeks of age shows that the ratio of germ cell populations remains stable throughout this time unlike in wild-type males which show that primary spermatocytes diminish and rapid growth of spermatids and spermatozoa is seen

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
