The book "Estrogen" has been edited to present the latest topics on estrogen's function and use as a therapeutic agent. Thousands of functions are carried out by estrogen; a few need to be better explained vis-à-vis their proper physiological

function. The collection of topics in this book aims to fulfill this need.
