About the book
The handbook maps how males and females develop in utero and during puberty through full-page, color-coded diagrams and scientific commentary. It follows chromosomes, genes, gonads, hormones, and genitalia through typical development and 25 disorders of sex development.
The visual and written approach brings together genetics, endocrinology, developmental biology, and clinical practice for educators, students, medical professionals, and general readers. Its left-page diagrams are paired with right-page explanations, and an expanded glossary covers more than 40 conditions.
Among the representative conditions discussed are Turner Syndrome, Klinefelter Syndrome, 5-Alpha Reductase Deficiency, Androgen Insensitivity Syndrome, Congenital Adrenal Hyperplasia, Hypospadias, Swyer Syndrome, and Ovotesticular Disorder.
The book focuses on biology and medicine, including medical ethics surrounding DSDs and the effects of unnecessary cosmetic surgeries on infants. The content utilizes primary scientific literature and was reviewed by doctors and clinicians working in sex development, DSD treatment, pediatrics, endocrinology, and restorative surgery.
