[Homoplastic transplantation of crayfish testes (Pontastacus leptodactylus leptodactylus (Eschscholtz, 1823)) in sexual rest into normal and destalked males and females: preliminary results].

Comptes rendus hebdomadaires des seances de l'Academie des sciences. Serie D: Sciences naturelles, 1977
Implantation of Crayfish testes in sexual rest into females leads to a new onset of spermatogenetic activity characterized by a precocious appearance of spermatocytes. However, these cells degenerate: their evolution never goes further than the pachytene stage of meiosis prophase.
