New Perspectives in Human Embryology

In the past decade, many new technologies and understandings in human embryology have rapidly been developing. This book collects five papers with the newest human embryology knowledge. The first chapter identifies some novel transcription factors involved in spermatogonial stem cells. Next, three papers in human assistant reproductive technology describe the application of abnormally fertilized eggs, noninvasive testing of preimplantation embryos, and the research progress of correcting pathogenic mutations by base editing. Finally, a perspective chapter discusses a new view of the endocrinology of pregnancy and parturition. Thus, this book provides perspective information for readers, especially embryologists, physicians, and obstetricians/gynecologists, for their clinical practice.
