Professionals must deal with difficult questions when anomalies, or sex errors, occur during development: What factors should be considered when assigning sex to a newborn of indeterminate sex? How can one address the concerns of adolescents with intersexual anomalies such as androgen insensitivity syndrome (AIS) and congenital adrenal hyperplasia (CAH)? What guidance is there for an individual who is considering sex reassignment? Now, this fully revised and expanded edition helps professionals answer these questions, providing the basic knowledge needed to inform and counsel parents of babies born with sexological disabilities and affected individuals themselves as they grow older. This extensively illustrated resource simplifies complicated concepts but retains medical and technical detail. Also, sharing his decades of counseling experience, the author emphasizes the importance of helping individuals attribute problems associated with an anomaly to the anomaly, rather than to themselves. Pediatricians, physicians, psychologists, counselors, sex educators, and others in the helping professions will find Sex Errors of the Body and Related Syndromes indispensable as a text, as a reference, and as a counseling guide. In addition, individuals with developmental sexual disabilities and their families will turn to this reliable resource for the clear, concise information they need to help them make critical decisions.
