N normal phenotype
endocrine/exocrine glands
N
• normal gonadotrope cellularity
• lactotropes are reduced in number in females
• lactotropes were undetected in males
• reduced somatotrope cellularity
• thyotrope hyperplasia and hypertrophy
• disorganized follicles
• seminal glands were not readily visible, consistent with testosterone deficiency
• follicles were reduced in size
• no progress beyond the preantral stage
• development of the tubules ceased perinatally
• size reduction observed at 8 weeks of age

growth/size/body
• mice were approximately half the size of wild-type littermates at 4.5 weeks of age
• first evident between 2 and 3 weeks of age
• no gender difference in size, putatively due to the decrease in testosterone levels

homeostasis/metabolism
• serum testosterone was undetected in male mice

reproductive system
• spermatogenesis was blocked at meiosis I
• seminal glands were not readily visible, consistent with testosterone deficiency
• follicles were reduced in size
• no progress beyond the preantral stage
• development of the tubules ceased perinatally
• size reduction observed at 8 weeks of age
• underdeveloped and threadlike at 3 weeks of age

nervous system
• lactotropes are reduced in number in females
• lactotropes were undetected in males
• reduced somatotrope cellularity
• thyotrope hyperplasia and hypertrophy

cellular
• spermatogenesis was blocked at meiosis I
