N normal phenotype
mortality/aging
• only about 6% of mice survive to adulthood
• neonatal lethality, with about 6% of mice surviving to adulthood

growth/size/body

reproductive system
• reduction in total number of spermatogenic cells, however spermatogenesis proceeds through meiosis and reaches round spermatid and even elongated spermatid stages
• spermatocytes and spermatids appear to be constantly depleted, leading to a complete lack of spermatozoa in the epididymis
• about 2-fold increase in apoptotic cells, mainly spermatocytes and early round spermatids, in the testes
• males are completely infertile
