As human in vitro fertilization (IVF) technique rapidlydevelopsininfertilitytreatment,notonlyanimalIVFhasoffereda veryvaluabletooltostudymammalianfertilizationandearlyembryodevelopmentas treatment, but also its commercial applications have being increased quickly. So far, this technologyhasgonethrough threemajorchanges, thatis,(1)traditionalembryo transfer(invivoembryoproductionbydonorsuperovulation)inanimals,especiallyin cow,(2)invitroembryoproductionbyovumpickupwithinvitrofertilization(OPU‐ IVF)in humanand animalsand(3)notablycurrentcloningtechnique bysomatic cell nuclear transfer and transgenic animal production. Embryo transfer technology has widelybeenusedinanimalindustrytoimproveanimalbreeds. Inhuman,manyIVF cliniccentershavebeensetupforinfertilitycoupletreatmentoverthewhole world. As embryo transfer techniques have accumulated over long period, many kinds of books about embryo transfer on human and various animals have been published. Most of books have described embryo transfer procedures and manipulation protocols. The purpose of this book doesnotconcentrate on thedetaildescription of basic embryo transfer techniques and procedures, while we will update and review some new developed theories and technologies and focus on discussing some encountered problems during embryo transfer and give some examples how to improve pregnancy rate by innovated techniques so that readers, especially embryologists and physicians for human IVF programs, may acquire some new and usableinformationaswellassomekeypracticetechniques. Thisbookcontainsfourpartswith16chapters.Firstly,anoptimalstimulationscheme for ovaries, particularly natural and minimal stimulation of ovaries, has been discussed in the first part. Then, one paper analyzed that how many oocytes per retrieval willbe thebestforhumanIVFpractice.Ifonestimulation schemeproduces too many eggs, it often results in hyperstimulation syndrome. Thus, a chapter reviewed hyperstimulation syndrome diagnosis, prevention and treatment. In the second part, some advanced technologies in insemination have been listed. After introduction of normal sperm physiology, sperm meiotic chromosome abnormalities and DNA fragmentation infertile patients are analyzed. Then, newly developed intracytoplasmic sperm injection (ICSI) techniques, such as intracytoplasmic X Preface morphologically‐selected sperm injection (IMSI) and selection of hyaluronan bound spermforuseinICSI(PICSI), have beenreviewed.Finally, weintroducedsomenew techniquesandmethodswhichcanmakeazoospermicmenrealizetheirdreamtohave children. In the third part, it will mainly discuss how to increase pregnancy rate by improving embryo transfer procedures including optimal embryo transfer skills, blastocystselectionandsingleembryotransfer,andtherelationshipofintercourseand pregnancy success rate. In the last part, endometrial receptivity and embryo implantationarediscussed,interestingly,morethan20biomarkershavebeenfoundin uterus to determine embryo implantation window and pregnancy failure.
