Autógenos

Autógenos is the plural form of autógeno, a term used in Spanish to describe processes, materials, or structures that originate within a system or organism. The root comes from auto- “self” and -geno “origin,” signaling self-origin or internal production. The exact meaning varies by field, but the common thread is self-generated or endogenous origin.

In metallurgy and materials science, autógena (and by extension autógenos) refers to welding or cutting without added filler metal. Autogenous welding uses heat from the same metal pieces to fuse them, producing joints without external material. The technique is valued for simplicity and cleanliness but is limited to certain materials, thicknesses, and joint designs.

In psychology and physiology, autógenos is associated with autogenic training (entrenamiento autógeno), a relaxation method developed in the early 20th century. It relies on self-suggestion to elicit physiological responses such as warmth and heaviness in the limbs, with aims of reducing stress and improving concentration.

In biology and medicine, the term can denote substances or tissues derived from the same individual, i.e., autogenous or autologous sources. This usage appears in discussions of autografts or therapies that use the patient’s own cells or tissues. Terminology can vary by language and discipline, and autógenos is often contextual rather than a single standardized term.

Overall, autógenos denotes self-origin across disciplines, with distinct applications in welding, relaxation techniques, and biomedical contexts.
