Steroid signaling and temperature-dependent sex determination — reviewing the evidence for early action of estrogen during ovarian determination in turtles. Expression profiles of Dax1, Dmrt1and Sox9 during temperature sex determination in gonads of the sea turtle Lepidochelys olivacea.
Variation in reproductive behavior within a sex: neural systems and endocrine activation. Hatchlings from single-sex producing temperatures also had higher first-year survivorship than the hatchlings from the temperature that produces both sexes. The authors went on to identify these proteins as heterogeneous nuclear ribonucleoprotein particles hnRNPs.

Charles Deeming. Retrieved April 16, — via ETI. 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. Although few previous studies had supported the theory in reptiles, Pieau proposed TSD as an alternative to genotypic sex determination.
