About the book
Embryogenesis, which usually involves the first eight weeks of development after fertilization, is an incredibly complicated process. As the development of various assisted reproductive technologies in last decade, some navel discovers and concepts such as epigenetics, mitochondrial functions have been formed on embryogenesis. Thus, we urgently need to update some navel findings and to summarize new theories in human embryogenesis for embryologists and physicians in human in assisted reproductive technology. This book will concentrate on discussing human embryogenesis based on current assisted reproductive technologies including oocytegenesis, spermgenesis, sperm fragmentation check and good sperm selection, insemination, in vitro fertilization (IVF), introcytoplasmic sperm injection(ICSI), sperm and egg combination, embryo culture, embryo formation with gene expression and regulation, mitochondrial change and function, epigenetics, assisted zona hatching (AZH), embryo section technology, preimplantation genetic testing (PGT including PGT-A for aneuploidy, PGT-M for mutations and PGT-SR for structural rearrangements), and recent developed gene editing in embryos. These new technique and theory discussions intend to provide the reader with a comprehensive overview of the current state-of- the-art in human assisted reproductive technology area so that they are will further improve current IVF technology success rate and make many infertile couples realize their dream to have a baby in their family.
