Abstract
RESULTS of biological assays have shown Conger conger ovary1 as well as other teleost ovaries2–6 to contain œstrogenic material. No indication of the chemical structure of the steroids present in the ovaries of these fishes has so far been ascertained. Only recently œstradiol-17β has been identified in the ovarian extracts of Salmo irideus and œstradiol-17β, œstriol and 16-epi-œstriol in the ovarian extracts of Cyprinus carpio7.
