Contrariwise to a previous report (Takeda, 1999),
we have been unable to consistently detect sexual
steroids through sensitive specific RIAs, both in the
testis and the haemolymph of this apple-snail.
Therefore we have looked for presumably paracrine
tissues in the genitalia that could sustain their
development. Zencker-fixed genital organs of adult
males were stained with haematoxylin, eosin and
light green. Epithelioid tissues composed by
elongated cells bearing a vacuolar-granular
cytoplasm and associated to haemolymphatic
spaces, were found underneath exocrine and
covering epithelia of the penial sheath, and the
exocrine epithelium of the prostate gland. It is
suggested that this tissues may be involved in
sustaining development of the masculine genitalia
in Pomacea canaliculata.Pomacea canaliculata.
