Protogen.

The word ovoprotogen is a combination of two Latin-derived terms: ovo and protogen.
The term ovo comes from the Latin word ovum, which means egg. It is often used as a prefix denoting something related to eggs.
The term protogen comes from the Greek word protos, meaning first, and the suffix -gen, which means producer or originator. It is commonly used to describe the first or primary stage of something.
Therefore, ovoprotogen can be understood to mean originating from or related to eggs or the first or earliest stage of development involving eggs.
