Symposium on Nuclear Sex covers the proceedings of the 1957 Symposium on Nuclear Sex, held at King's College Hospital Medical School. This book is organized into three sections encompassing 22 chapters that consider the problem of developmental sex anomalies and certain cytological aspects. After a brief presentation of the history of chromosomal sex and sex anomalies, this book goes on exploring the genetic and cytological observations related to nuclear sex, with a particular emphasis on the genetic implications of nuclear sexing. The second part deals first with the fundamentals of sex chromosomes and the development of human intersexes. The discussion then shifts to problems in intersexuality, children of homosexuals, transvestism, sexual development disturbances, and the nature of the genetic defect in Klinefelter's syndrome. The third part covers studies of the nuclear sex of a group of teratomas and other sex tumors. This book will prove useful to workers and researchers in the fields related to nuclear sexing including anatomy, biochemistry, biology, clinical medicine, cytology, endocrinology, genetics, pathology, physiology, psychology, and surgery.
