title: [Is sexual differentiation in cephalopods embryos (Sepia officinalis L) under endocrine control (author's transl)].
abstract: The sex differenciation in the gonad of the cuttlefish is only evident after the hatching, -- the "A" cells become spermatogonia or ovogonia. In the embryonic gonads, bigger cells called "B" seem participate in this differenciation (ultrastructural active aspects in concordance with sexual differentiation).
