Resumen:
Temperature sex determination (TSD) in reptiles has been studied to elucidate themechanisms by which temperature is transformed into a biological signal that determinesthe sex of the embryo. Temperature is thought to trigger signals that alter geneexpression and hormone metabolism, which will determine the development offemale or male gonads. In this review, we focus on collecting and discussing importantand recent information on the role of maternal steroid hormones in sex determinationin oviparous reptiles such as crocodiles, turtles, and lizards that possess TSD.In particular, we focus on maternal androgens and estrogens deposited in the eggyolk and their metabolites that could also influence the sex of offspring. Finally, wesuggest guidelines for future research to help clarify the link between maternal steroidhormones and offspring sex.
