reproductive system
• at 18 weeks of age (J:170710)
• at P30 compared to heterozygous controls (J:170710)
• in some ovaries a disproportionate increase in oocyte size relative to the follicular cells is seen at P30 (J:170710)
• increase in the number of follicles at P30 (J:170710)
• marked decrease in the number of primary follicles at P60 (J:170710)
• increase in the number of secondary follicles at P30 (J:170710)
• at 18 weeks of age ovarian follicles are absent in 3 of 4 mice and the remaining mouse has a few degenerating primordial follicles (J:170710)
• at P3 some primordial follicles show an increase in the size of primary oocytes (J:170710)
• at P14 most of the remaining primordial follicles contain an enlarged primary oocyte surrounded by spindle-shaped/squamous follicular cells (J:170710)
• marked decrease in the number of primordial follicles at P60 (J:170710)
• at 18 weeks of age 1 of 4 mice has a few degenerating primordial follicles (J:170710)
• at P30 compared to heterozygous controls (J:170710)
• at 1 year of age occasional females have grossly enlarged ovaries (J:170710)
• apparent asynchronous development of the oocyte and follicle (J:170710)
• females lose fertility by about 8 weeks of age
• however, males display normal fertility
• oocytes are less likely to have a polar body on ovulation (J:170710)
• apparent asynchronous development of the oocyte and follicle (J:170710)
• at P3 some primordial follicles show an increase in the size of primary oocytes (J:170710)
• oocytes are less likely to have a polar body on ovulation (J:170710)
• increased proportion of superovulated oocytes that are arrested at metaphase of meiosis I (J:170710)
• oocytes cultured overnight are more likely to fragment than those from superovulated heterozygous females (J:170710)

tumorigenesis
• found in grossly enlarged ovaries at 1 year of age (J:170710)
• Background Sensitivity: teratomas are seen in about 1 in 6 mice of aged up to 8 months in mice on an FVB/NJ background but not in mice on an inbred C57BL/6J background (J:170710)

mortality/aging
• females lose fertility by about 8 weeks of age
• however, males display normal fertility

endocrine/exocrine glands
