estrogen-like

The term is a modern scientific compound. The first element, 'estrogen', is itself a 20th-century formation from the Greek oistros, originally meaning a gadfly or a state of frenzy, which was applied biologically to the period of sexual frenzy in animals (estrus), combined with the suffix -gen (producer). Thus, estrogen literally means "a producer of estrus". The second element, the native English suffix 'like', meaning "having the form or character of", is attached to create an adjective. The compound 'estrogen-like' therefore logically describes any substance that mimics the form or function of the primary female sex hormone, bridging a vivid ancient concept of frenzied impulse with a precise modern biochemical descriptor.
