reproductive system
• seminal vesicle glands continue to grow as mice age and show pathologic changes, including regions of necrosis and hemorrhage
|
• seminal vesicles are significantly enlarged in adult males
|
• seminal vesicle-to-body weight ratio is significantly increased in adult males
|
• adult testes exhibit significantly more seminiferous tubules per cross-section
• however, seminiferous tubule diameter and ratio of stage VIII to the total numbers of seminiferous tubules per cross-sectional area remain normal
|
• Leydig cells retain their ability to proliferate and functionally generate a hyperandrogenic condition
• an indicator of adult Leydig cells, Hsd3b6, fails to show the expected developmental increase in adult testes
|
• adult testes are significantly enlarged
|
• testicular interstitial compartments are significantly expanded and contain more MKI67+ cells than wild-type testes
• several Leydig cell progenitor-associated transcripts remain elevated in adult testes
|
• testis-to-body weight ratio is significantly increased in adult males
|
• serum testosterone levels are significantly increased, androgen-responsive tissues are hyperstimulated, and sperm production is significantly greater than in wild-type males
• testis hyperfunctionality is driven by altered developmental maturation of Leydig cells
|
• total sperm count is significantly increased in adult males
• however, sperm exhibit normal patterns of motility
|
• precocial development of the scrotal region at time of weaning (P21)
|
• females are subfertile; only 58% mated during cohabitation with wild- type males and only 57% of the seminal plug-positive females were pregnant on gestation day 9.5
• however, male fertility is relatively normal
|
homeostasis/metabolism
• serum testosterone levels are significantly increased in adult males
|
• serum LH levels are significantly increased in adult males
|

|
• Lhb (luteinizing hormone beta) mRNA levels are significantly increased whereas Fshb (follicle stimulating hormone beta) mRNA levels are significantly reduced in the pituitary of adult males
• however, serum FSH levels are normal in adult males
|
• serum testosterone levels are significantly increased, androgen-responsive tissues are hyperstimulated, and sperm production is significantly greater than in wild-type males
• testis hyperfunctionality is driven by altered developmental maturation of Leydig cells
|
growth/size/body
• body weight is significantly increased in adult males
|
nervous system
• Lhb (luteinizing hormone beta) mRNA levels are significantly increased whereas Fshb (follicle stimulating hormone beta) mRNA levels are significantly reduced in the pituitary of adult males
• however, serum FSH levels are normal in adult males
