- An
oogonium (pl.:
oogonia) is a
small diploid cell which, upon maturation,
forms a

- germ cell (PGC),
which then
undergoes mitosis,
forming oogonia.
During oogenesis, the
oogonia become primary oocytes. An
oocyte is a form of

called oogonia.
Development proceeds and the
oogonia become fully surrounded by a

- and the
gametogonia turn into
oogonia,
which become fully surrounded by a
layer of

completely without the aid of spindle-coordinating centrosomes. The
creation of
oogonia traditionally does not

After migration primordial germ
