In many reptile species, sexual differentiation of gonads is sensitive to temperature during a critical period of embryonic development (thermosensitive period, TSP). Experiments carried out with different models among which turtles, crocodilians and lizards have demonstrated the implication of estrogens and the key role played by aromatase (the enzyme complex that converts androgens to estrogens) in ovary differentiation during TSP and in maintenance of the ovarian structure after TSP. In some… CONTINUE READING
