Effect of hermaphroditic gland homogenate on the regulation of the gametogenesis in Helix pomatia (Gastropoda, Pulmonata).

On the effect of ovotestis (glandula hermaphroditica) homogenate the number of ovocytes of 1st and 2nd order and of the eggs increased very significantly, while spermiocytes of 1st order sperms significantly decreased in number. When snails with extirpated tentacles were injected with ovotestis homogenate the ovogenesis was activated which was proved by a significant increase in the number of ova.
