• no defects were observed in the postnatal testes

|
• reduced number of oocytes in the postnatal ovary
|
• progressive decrease in primordial germ cells in both females and males; ~25% that of wild-type controls at E11.5 and ~10% at E12.5
• in spite of the reduced PGC number in males, normal numbers of differentiating germ cells were observed in older males, putatively due to an increase in the mitotic proliferation of spermatogonia
