Hormonal Proteins and Peptides, Volume XI: Gonadotropic Hormones deals with gonad stimulating hormones that cause precocious sexual maturity. This book begins by reviewing the relationship of the chemical structure to the biological activity of gonadotropins and chorionic hormones, followed by a brief presentation on the in vitro bioassay methods. A comprehensive discussion on some aspects of the molecular mechanism of gonadotropin action is also provided. This publication concludes with an analysis of the immunobiology of gonadotropins. This book is intended for endocirnologists, but is also useful for medical practitioners and researchers concerned with gonadotropic hormones.
