This manual covers all possible aspects of managing a child with differences in sex development, an entity easily missed by the unsuspecting clinician. Managing such children is challenging due to various processes (genetic, hormonal, environmental, chromosomal, and environmental) involved in developing gonads and brain imprinting. The entity of Gender dysphoria adds further to this complexity. With a global uproar caused by the cropping up of medicolegal issues concerning sex allotment and sex of rearing, a need is felt to know about the line of approach to address the problems of management of these children, which does not stop at medical and surgical treatment. Whereas many social and legal organizations are relentlessly working for the cause of such children, there is a lack of comprehensive literature on the round management of such children, which makes the book more of an essential addition to the existing reading material. Esteemed writers give all these aspects and explain lucidly with the help of tables, figures, and diagrams.
