The first thing children ask about sex is typically, "Where do babies come from?" This, the most perplexing scientific question of all time, was hailed by the ancient Greeks as "the mystery of mysteries". Throughout history the most intelligent and well-educated men and women have struggled to understand how we reproduce, and the full picture is far from complete. In the mid-17th century, a theory of reproduction - preformation - sparked an intensely heated debate that continued for over 100 years. Preformation proposed that miniature creatures waiting to be born existed inside each potential parent much like a Russian nesting doll. It was thought that God placed these beings during Creation and predetermined the precise moment that each would unfold and exist. In "The Ovary of Eve", Clara Pinto-Correia traces the fascinating and often-amusing history of this much-maligned theory, ultimately revealing its critical influence on the modern view of conception. Opinion on preformation was sharply divided. "Ovists" believed that preformed individuals existed in the egg, but "spermists" argued that the locus of perfection before birth was in the sperm.This controversy ranged beyond the narrow confines of biology. Most scholars were reluctant to allow perfection to women. After all, these debates occurred in a culture which held women responsible for the Fall and original sin and which saw women as imperfect or incomplete males. Yet spermism entailed a formidable moral dilemma, - why would God allow millions of preformed individuals to die with each ejaculate? Pinto-Correia recounts this controversy in all its complexity, revealing the religious, cultural and social climate of the day. Acknowledging that several modern authors have presented preformation as little more than an entertaining interlude in the study of reproduction, Pinto-Correia nonetheless seeks to recast preformation as an important theory with a precious legacy. Her book shows that the basic tenets understood by the old preformationists are still a crucial part of developmental biology and effect such state-of-the art techniques as cloning.

How does one make a decision today about in vitro fertilization, abortion, egg freezing, surrogacy, and other matters of reproduction? This book provides the intellectual and emotional intelligence to help individuals make informed choices amid misinformation and competing claims. Scott Gilbert and Clara Pinto-Correia, renowned scientists and communicators, speak to the couple trying to become pregnant, the woman contemplating an abortion, and the student searching for sound information about human sex and reproduction. Their book is an enlightening read for men as well as for women, describing in clear terms how babies come into existence through both natural and assisted reproductive pathways. The book first covers the most recent and well-grounded scientific conclusions about fertilization and early human embryology. It then discusses the reasons why some of the major forms of assisted reproductive technologies were invented, how they are used, and what they can and cannot accomplish.Most important, the authors explore the emotional side of using these technologies to become pregnant, focusing on those who have emptied their emotions and bank accounts in a valiant effort to get pregnant. This work of science and human biology is informed by a moral concern for our common humanity.

Laparoscopic Surgery of the Abdomen is intended to give the practicing surgeon or trainee an in-depth analysis of the technical aspects of the most commonly performed laparoscopic procedures, their indications, contraindications, and complications. Included are strategies to prevent complications as well as ways to handle them once they occur. Heavily illustrated, the book breaks new ground in visualizing operative procedures and problems. Seven sections, comprising the core curriculum of accepted procedures in laparoscopic surgery, present gallbladder disease, common bile duct exploration, hernia, colon diseases, anti-reflux procedures, acute abdomen and the role of diagnostic laparoscopy, and emerging procedures on the spleen and adrenals. Recognized leaders in the field tackle each section, emphasizing what to do when and how to solve acute situations. Laparoscopic Surgery of the Abdomen is a practical, must-have resource for the general surgeon, imparting the clinical insight needed for successful performance of the core miminally invasive procedures as well as a source of useful patient information for the office practice.

Although everybody is familiar with the dodo bird, very few people know its history. Yet this history is compelling when read as a fable of the negative impact of humans on Earth's ecosystems. The author describes the complexity of the factors involved in animal extinction. Although we think of ourselves as more ecologically aware than our ancestors, we are propelling extinction to alarming rates.
