"Systems theory looks at the world in terms of the interrelatedness and interdependence of all phenomenon, and in this framework an integrated whole whose properties cannot be reduced to those of its parts is called a system." Fritjof Capra, The turning point: science, society and the rising culture, p. 43


Endobiogeny is a terrain theory that assesses how the internal (endo-) life (bio-) of the body is generated and sustained (-geny). It is a systems theory of biology that considers the endocrine system to be the true manager of the body. The endobiogenic concept was conceived by Christian Duraffourd, MD, and its teaching developed by Dr. Duraffourd and Jean-Claude Lapraz, MD.

The modern biomedical approach has produced a highly detailed understanding of physiology, and offers impressive interventions for life-threatening and degenerative disorders. Endobiogeny neither rejects nor is outside this system because it is based on modern physiology. Where it differs from the standard biomedical approach is in its understanding of the body as a system, which owing to the interrelated and interdependent nature of its physiology, requires an integrated approach to history, evaluation and treatment.

Role of the Endocrine system

The body is an organized system. Endobiogeny considers the endocrine system to be the true manager of the body because it is the only system that is ubiquitous, self-managing and able to manage other systems simultaneously. From fetogenesis, the endocrine system is the first and primary system that manages childhood, puberty, pregnancy, parturition, genital pause, death, and adaptation against every stressor. Thus, the endocrine system is the primary object of study with respect to the structure and function of the body. As the initiator of adaptation, the autonomic nervous system plays an important role too.

The functionality of the body is evaluated through two key concepts: relativity and action. Functionality is not determined by quantitative serum levels of regulating factors but by their relative activity, one to another. These concepts help explain the mechanisms of installation and persistence of illnesses currently categorized as "functional" or "idiopathic."
