reproductive system
• increased oocyte retention
|
• longated shapes, pronounced cytoplasmic granularity and abnormal polar-body-like structure
|
• fewer total oocytes and no mature MII oocytes are detected
|
• abnormal spindle formation and chromosome alignment at the metaphase plate
|
• some follicles have 2 or 3 layers of granulosa cells indicating the beginnings of premature antrum formation
|
• 3-fold increase in number of secondary follicles
|
• some follicles house 2 oocytes
|
• impaired ovulation
|
• despite normal estrous cycle and mating behavior
|
• after super-ovulation of female mice and breeding with wild-type males, no two-cell embryos are collected 42 h later
|
