reproductive system
• less decidual response to mechanical stimulation
• reduced response to estrogen treatment
• growth reduced about 34% in castrated males after testosterone treatment
• smaller testes but structurally normal
• 19% reduction in testis/body weight ratio

homeostasis/metabolism
• after a low-iodine diet and propylthiouracil and L-T3, mice exhibit mild resistance to thyroid hormone compared with wild-type mice

endocrine/exocrine glands
• ductal development only about half normal at 8 weeks of age
• alveoli much less developed
• growth reduced about 34% in castrated males after testosterone treatment
• smaller testes but structurally normal
• 19% reduction in testis/body weight ratio

behavior/neurological
• increased escape latency in a Morris water maze
• slower swim speed
• tended to fall in a hanging wire test about 29% earlier than controls
• shorter latency to falling in a rotarod test and less improvement with repeated testing

nervous system
• absent at birth
• gradually reached normal levels by about age 10 days
• development of Purkinje cell precursors delayed from E10.5 to around E12.5

embryo
• reduced response to estrogen treatment
• less decidual response to mechanical stimulation

integument
• ductal development only about half normal at 8 weeks of age
• alveoli much less developed
