Sunderland MA : Sinauer Associates ; Journal of Heredity. Caring for Stranded Marine Animals. Aromatase helps to convert sex steroids, a group of hormones that influence sex development and reproduction, from male sex hormones androgens to female sex hormones estrogens.

  • In certain reptiles with temperature-dependent sex determination TSD , estrogens act as a signal for female differentiation. Because aromatase produces estrogens from androgens, this enzyme plays a pivotal role in TSD.
  • Turtles and tortoises are believed to have existed for about million years, making them among of the oldest organisms on Earth.
