This book brings together authoritative accounts by leaders in the field of reproductive biology, researchers who have closely investigated implantation. The subject is approached from several angles: biochemical, endocrinological, pharmacological, anatomic, and immunological.
The "contraceptive revolution" of the 1960s and 1970s introduced totally new contraceptive options and launched an era of research and product development. Yet by the late 1980s, conditions had changed and improvements in contraceptive products, while very important in relation to improved oral contraceptives, IUDs, implants, and injectables, had become primarily incremental. Is it time for a second contraceptive revolution and how might it happen? Contraceptive Research and Development explores the frontiers of science where the contraceptives of the future are likely to be found and lays out criteria for deciding where to make the next R&D investments. The book comprehensively examines today's contraceptive needs, identifies "niches" in those needs that seem most readily translatable into market terms, and scrutinizes issues that shape the market: method side effects and contraceptive failure, the challenge of HIV/AIDS and other sexually transmitted diseases, and the implications of the "women's agenda." Contraceptive Research and Development analyzes the response of the pharmaceutical industry to current dynamics in regulation, liability, public opinion, and the economics of the health sector and offers an integrated set of recommendations for public- and private-sector action to meet a whole new generation of demand.
The placenta is fascinating and complex. Basically foreign to the maternal body, it can be thought of as an organ transplanted onto the mother's host tissue. As such it embodies all the principles of tissue acceptance and rejection. Many of the risks of pregnancy and labor have now been eliminated and the placenta is likely to be at the root of many of the dangers to the unborn child that remain. A breakdown of the relationship between the placenta and the maternal tissue may turn out to be the cause of the majority of early lost pregnancies.
The placenta is an organ that connects the developing fetus to the uterine wall, thereby allowing nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. Proper vascular development in the placenta is fundamental to ensuring a healthy fetus and successful pregnancy. This book provides an up-to-date summary and synthesis of knowledge regarding placental vascular biology and discusses the relevance of this vascular bed to the functions of the human placenta.
The last step in the IVF treatment cycle, embryo transfer, is also the process with the highest failure rate. No matter how good the laboratory technique is, a successful pregnancy will not be achieved without meticulous preparation of the uterus to accept the embryo. This book reviews the scientific evidence on endometrial receptivity, including histological, hormonal, biochemical, and immunological factors. Practical and concise, it supports gynecologists and embryologists to make evidence-based decisions that can influence the success rates of implantation and live births. Part of a series of books offering treatments and strategies for fertility and conception to optimize IVF outcomes, this volume is for all clinicians and embryologists working in reproductive medicine.
