Sex steroids are involved in sex determination in almost all vertebrates, including species
with temperature-dependent sex determination (TSD). It is well established that aromatase …

Temperature-dependent sex determination (TSD) is a mechanism in which environmental
temperature, rather than innate zygotic genotype, determines the fate of sexual …

Most anurans have no identified sex-markers; therefore, alternative methods for
identification of early changes in sex ratios are required. In this study, Lithobates sylvaticus …

Simple Summary The Chinese soft-shelled turtle has obvious sex dimorphism, which is an
important aquatic economic species in China. Exogenous hormones can cause the sexual …

In species with temperature-dependent sex determination, embryonic gonadal differentiation
can be modified by exposure to exogenous chemicals such as environmental contaminants …

In many turtles the temperature during the middle of incubation determines the gonadal sex
of the hatchling. In the red-eared slider turtle (Trachemys scripta), an incubation temperature …

Aromatase, encoded by Cyp19a1, is essential in estrogen biosynthesis and crucial in sex
differentiation and ovary development. Although aromatase regulates the proliferation …

Vertebrate sexual fate can be established by environmental cues (eg, temperature-
dependent sex determination, TSD) or by genetic content (genotypic sex determination …

Temperature-dependent sex determination (TSD) was first discovered in reptiles. Since
then, a great diversity of sex-determining responses to temperature has been reported …

Sex determination in egg‐laying amniotes may be fundamentally different from that of
placental mammals. The mammalian ovary differentiates normally in the absence of …
