The Plasticity of Sex: The Molecular Biology and Clinical Features of Genomic Sex, Gender Identity and Sexual Behavior provides a comprehensive view on the development of human sexuality. As there has been a crescendo of interest over the past several decades about the nature and diversity of human sexuality, this reference brings the evidence-based research into one place. The emergence of issues surrounding gender identity, genital ambivalence and the transition from one sex to another is striking, with the public and treating physicians alike clamoring for an evidence-based, comprehensive treatment of human sexuality and all its variations. This is a must-have reference for biomedical researchers in endocrinology, neuroscience, development biology, medical students, residents, and practicing physicians from all medical areas.
