A fish (Sparidae) Spondyliosoma cantharus L. has been chosen because of his protogynous hermaphroditism. Histology and immuno-precipitation show that during the period of vitellogenesis or after hormone treatments (androgens and estrogens), the liver of female takes a caracteristic apperance. This aspect has been observed before in the gonochoric species and it concerns the elaboration of the vitellin proteins and their blood transportation from liver to ovary. The immatures and males are sensitive to the estrogens, but react only exceptionally to androgens.
