| Résumé : | In vitro addition of progesterone to oocytes taken out of Pleurodeles females which had received injections of Pregnyl markedly increases the frequency of maturations. Progesterone alone induced the maturation, in a high percentage of the cases, in Ambystoma mexicanum oocytes taken out of 3 females which had been reared under special conditions. Cytological analysis has not shown any major difference in the maturation of Urodeles and Anurans. The significance of these results is discussed. |
