N normal phenotype
cellular
• 75% reduction of epididymal sperm count relative to wild-type
• 40% reduction in the number of motile sperm relative to wild-type

endocrine/exocrine glands
• blocked prior to antral follicle formation
• progressive reduction in size beginning at 14 days of age
• however, serum testosterone levels in males were similar to those of wild-type and the epididymides and seminal glands were of normal size

homeostasis/metabolism
• 50% decrease relative to wild-type
• FSH was undetected in the pituitary

reproductive system
• 75% reduction of epididymal sperm count relative to wild-type
• 40% reduction in the number of motile sperm relative to wild-type

• progressive reduction in size beginning at 14 days of age
• however, serum testosterone levels in males were similar to those of wild-type and the epididymides and seminal glands were of normal size
