The field of human artificial reproductive technology (ART) is continually advancing and has witnessed significant changes since the inception of Louise Brown in 1978. Though Louise Brown herself was conceived after the trans fer of a blastocyst, there remain significant confusion and debate regarding the stage at which the human embryo conceived in the laboratory should be replaced in the mother. Developments in culture media formulations, leading to the introduction of sequential media, have brought the role of the blasto cyst in human ART back into the spotlight. It was due to this resurgence of interest in the niche of extended culture in human infertility treatment that the symposium on "ART and the Human Blastocyst" was held. of this meeting within this volume bring to the forefront The proceedings the main issues raised with the transfer of embryos at the blastocyst stage. It is evident from the chapters that follow that ART needs to be perceived as a continuum of procedures, each one dependent on the preceding one, and all equally as important as each other. That is to say, the development of a com petent embryo is ultimately dependent on the quality of the gametes from which it was derived. With regard to the oocyte, this then places the emphasis on the physician to use a stimulation protocol that both produces quality oocytes and does not impair endometrial function. Maintenance of gamete and embryo quality is the laboratory's role.

This volume contains the proceedings of the International Symposium on Embryo Implantation: Molecular, Cellular and Clinical Aspects, held from October 3-6, 1997 in Newport Beach, California. Internationally recognized experts discuss the development and future of human in vitro fertilization and embryo implantation, the cellular aspects of implantation, hormonal regulation, molecular markers of receptivity, trophoblast factors, primate models and animal studies, and transcriptional regulation of maternal-fetal recognition.

The advent of assisted conception procedures such as in-vitro fertili sation (IVF) has provided the impetus for exploration of the factors that lead to the establishment of pregnancy. This collection of papers from leading research workers brings together current concepts of the processes which may be of importance in implantation. The complex signals from the embryo to the ovary, endometrium and myometrium are now being revealed through studies in both primates and other mammalian species. This book addresses the interrelationship of pituitary and ovarian hormones in controlling ovulation and the preparation of the intrauterine environment for implantation. Once fertilisation has occurred and trophoblast has formed, the next vital step is the production of materials which signal the presence of the pregnancy to the rest of the body. Trophoblastic proteins and other early-pregnancy factors are prime candidates for this role. Recent studies have emphasised the importance of the intrauterine environment in implantation. Specific secretory products of the endometrium have great potential in this process. The prostaglandins also play an essential part. Immunological adjustments are now considered a condition for the successful establishment of pregnancy. The possible use of immuno therapy in the treatment of recurrent abortion has highlighted interest in this area. The use of immunological techniques for contraception are in their infancy but offer much hope for the future.

Long was I hugg'd close-long and long. Immense have been the preparations for me, Faithful and friendly the arms that have help'd me. Cycles ferried my cradle, rowing and rowing like friendly boatmen. For room to me stars kept aside in their own rings, They sent influences to look after what was to hold me. Before I was born out of my mother, generations guided me, My embryo has never been torpid, nothing could overlay it. -Walt Whitman, "Song of Myself" The womb is the seat of all mammalian life. In pregnancy, the uterus acquires this impor tance with the arrival of the fertilized egg, which takes up residence for periods ranging from about 2 weeks in the opossum to about 2 years in the elephant. The arrival of the embryo signals a crucial time for the establishment of pregnancy. For several days the blas tocyst remains free in the uterine lumen, where it depends on uterine secretions for its sur vival and differentiation. During this time, essential changes in the endometrium take place in preparation for attachment of the blastocyst and implantation. Early embryonic loss is an economic problem of global proportions in animal husbandry, where, in pigs and cattle for example, some 30% of all fertilizations fail to result in a pregnancy. In humans this figure may be even higher, and estimates of early spontaneous abortions range from 40 to 60% of all conceptions.

This concise work on embryo transfer is yet another contribution to the persevering effort to disseminate latest information on the science and skill of performing a traumatic and successful embryo transfer. It is the most critical culmination of the assisted reproductive technology (ART) stimulation cycle, and a rate-limiting step in dictating the success of treatment. The well-worded chapters draw the reader’s attention to significant aspects before initiating the actual embryo transfer, such as possible causes of failure at the embryo transfer stage, uterine evaluation, mock embryo transfer (ET), experience of the physician, and the use of ultrasound-guidance to monitor ET. The protocol for difficult transfers, variables that affect the success of ET, and the influence of the catheter used for ET have also been dealt with. The unique feature of this book is its pragmatic approach that can translate into solutions to the numerous frustrating ART failures that more often than not, may be attributed to an inefficient ET procedure. It helps the reader understand the integrity of embryo transfer, unravel its obvious simplicity and bridge the success between the several steps of ART. By highlighting the impeding problems associated with ET procedure and providing valid, scientific solutions, this stimulating edition will help the readers improve the ART success rates in their clinical practice.
