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.
