cellular
• at 8 weeks, hemizygous mutant males show a marked reduction of the total number of germ cells in their seminiferous tubules, although the number of spermatogonia is apparently normal
• no spermatozoa are detected at 8 weeks of age

reproductive system
• at 8 weeks, hemizygous mutant males show a marked reduction of the total number of germ cells in their seminiferous tubules, although the number of spermatogonia is apparently normal
• no spermatozoa are detected at 8 weeks of age
• at 8 weeks, spermatogenesis is incomplete, as primary spermatocytes are readily observed, but no secondary spermatocytes, spermatids or spermatozoa are detected
• spermatogenesis is arrested at meiosis I
• at 8 weeks of age
• at 8 weeks of age
• at 8 weeks of age, the tunica propria is more prominent in the mutant testis with 2-3 layers visible relative to one layer found in wild-type males
• although Leydig cells are present in similar numbers to those found in wild-type testes, the interstitial connective tissue appears to be more pronounced in mutant testes
• at 8 weeks, the seminiferous tubules in mutant testis are smaller in diameter relative to wild-type controls
• at 8 weeks of age, mutant testes are smaller than wild-type
• at 8 weeks of age, the testis mass of hemizygous mutant males is reduced by 95% relative to wild-type control males
• mutant testes are located intra-abdominally
• hemizygous mutant males display female external genitalia

growth/size/body
• at 8 weeks and 10 to 25 weeks hemizygous mutant males weigh less than wild-type males; their mean body weight is intermediate between wild-type male and female control littermates
• contrary to expectation, hemizygous mutant males do not become heavier than wild-type control males with increasing age

homeostasis/metabolism
• at 9 weeks of age, serum testosterone levels of hemizygous mutant males are reduced relative to wild-type control littermates

endocrine/exocrine glands
• at 8 weeks of age
• at 8 weeks of age
• at 8 weeks of age, the tunica propria is more prominent in the mutant testis with 2-3 layers visible relative to one layer found in wild-type males
• although Leydig cells are present in similar numbers to those found in wild-type testes, the interstitial connective tissue appears to be more pronounced in mutant testes
• at 8 weeks, the seminiferous tubules in mutant testis are smaller in diameter relative to wild-type controls
• at 8 weeks of age, mutant testes are smaller than wild-type
• at 8 weeks of age, the testis mass of hemizygous mutant males is reduced by 95% relative to wild-type control males
• mutant testes are located intra-abdominally
