reproductive system
N |
• phenotypes observed in testes and ovaries at 6 weeks of age are recoverable by 3 and 6 months of age
|
• few sperm are seen within the epididymis at 6 weeks of age
|
• observe areas of spermatocyte loss from the testis cords at 6 weeks of age
|
• 6-8 week old females have decreased follicle development
|
• 6-8 week old females have reduced numbers of theca cells in the maturing follicles of the ovaries, although a thin, broken theca interna is seen in the ovary
|
small ovary
(
J:142042
)
• 6-8 week old females have small ovaries
|
• fewer steroid-producing cells are seen at E12.5-E14.5 in the testis
|
• testis cord formation is delayed at E12.5-E14.5
• observe areas of spermatocyte loss from the testis cords at 6 weeks of age
|
• reduction in number of adult Leydig cells at 6 weeks of age
|
small testis
(
J:142042
)
• testes are smaller at 6 weeks of age but by 10 weeks they appear normal sized
|
• 6-8 week old females have underdeveloped uteri
|
• delay in fertility, however by 3 to 6 months of age, mutants become fertile
|
anovulation
(
J:142042
)
• 6-8 week old females show no evidence of ovlulation
|
homeostasis/metabolism
• 6-8 week old females exhibit lower estradiol levels
|
• 75% of mutants exhibit low testosterone levels in the testes at 6 weeks of age, however by 10 weeks, levels are higher
|
endocrine/exocrine glands
• 6-8 week old females have decreased follicle development
|
• 6-8 week old females have reduced numbers of theca cells in the maturing follicles of the ovaries, although a thin, broken theca interna is seen in the ovary
