N normal phenotype
mortality/aging
• most female mice die between 4 and 6 weeks of age and all die by 9 weeks of age
• male mice survival 19 weeks

reproductive system
• male germ cells are depleted and degenerated
• tubule-like structures resembling Sertoli-like cells are found adjacent to tumor unlike in wild-type mice
• mice develop aggressive bilateral ovarian tumors with hemorrhagic foci
• tumors contain granulosa-like cells
• tubule lumens are filled with Sertoli cells unlike in wild-type mice
• mice develop testicular tumors formed of granulosa-like cells with numerous sites of hemorrhage
• mice fail to develop early Sertoli cells unlike in Esr1tm1Ksk Inhatm1Bay or Esr2tm1Unc Inhatm1Bay double homozygotes

neoplasm
• mice develop aggressive bilateral ovarian tumors with hemorrhagic foci
• tumors contain granulosa-like cells
• mice develop testicular tumors formed of granulosa-like cells with numerous sites of hemorrhage
