Endocrine disrupting chemicals (EDCs), including the mass-produced component of
plastics, bisphenol A (BPA) are widely prevalent in aquatic and terrestrial habitats. Many …

This paper reviews the current knowledge concerning the endocrine and environmental
regulations of both gonadal sex differentiation in gonochoristic and sex inversion in …

Abstract Cytochrome P450 aromatase (CYP19) is the terminal enzyme in the steroidogenic
pathway that converts androgens (eg, testosterone) into estrogens (eg, estradiol) …

As a first step toward understanding estrogen's role in neurodevelopment, a PCR cloning
strategy was used to isolate complementary DNAs encoding two distinct cytochrome P450 …

In many reptile species, sexual differentiation of gonads is sensitive to temperature during a
critical period of embryonic development (thermosensitive period, TSP). Experiments carried …

Sex determination is the process deciding the sex of a developing embryo. This is usually
determined genetically; however it is a delicate process, which in many cases can be …

In the tilapia Oreochromis niloticus, sex is determined genetically (GSD), by temperature
(TSD) or by temperature/genotype interactions. Functional masculinization can be achieved …

This book is comprised of 12 chapters covering topics in reptilian incubation. The chapters
are written by several authors. This book is aimed at serving as a valuable reference text for …

In many vertebrate species, sex is determined at fertilization of zygotes by sex chromosome
composition, knows as genotypic sex determination (GSD). But in some species—fish …

A brain aromatase gene was identified from the Nile tilapia Oreochromis niloticus. The cDNA
sequence of this gene differed from that of the ovarian aromatase gene previously reported …
