Endogen

Endogen is a term used across multiple disciplines to denote something that originates from within a system, as opposed to being introduced from outside. In many contexts, the related adjective endogenous is preferred, but Endogen may appear as a noun or brand name in various settings.

In science and medicine, endogenous refers to processes, substances, or rhythms produced inside an organism or system. Examples include endogenous hormones, endogenous metabolism, and endogenous circadian rhythms. The concept emphasizes internal origin and regulation rather than external causation.

In economics and social sciences, endogenous factors are those determined within the model or system being studied. This contrasts with exogenous factors, which come from outside the system. Endogenous growth theory, for instance, explores how internal mechanisms like innovation, human capital, and institutions drive sustained economic growth.

Endogen also appears as a proper name in some contexts, including company names, software projects, or product lines. Because there is no single, universally recognized entity called Endogen, references should specify the particular organization or context involved.

Etymology wise, endogenous derives from Greek roots meaning within and to be born or produced, reflecting the idea of internal origin. The term is used across disciplines to signal internal causation, development, or generation.
