| The oogonial initial penetrates the antheridial initial and rapidly expands to form the oogonium. |
| It could provide technical support for the basic research on regulation of c-FLIP on the bovine oogonium development, and be important for further research. |
| It is seldom that more than one antheridium applies itself to an oogonium. |
| The parent also contains antheridia which produce sperm and an oogonium which produces the egg. |
| In humans, primordial germ cells or oogonium are the first stage of development into ovums, or mature eggs. |
