To obtain much information on round spermatids, culture of round spermatids under in vitro conditions is an effective method. Mouse round spermatids cultured in the presence of recombinant FSH and testosterone show normal differentiation into elongating spermatids, and the elongated spermatids show normal oocyte activation and fertilization.","PeriodicalId":126001,"journal":{"name":"Reproductive Immunology and Biology","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126943579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is also true that the rate of development of the embryo into the blastocyst after ICSI is lower than that after in vitro fertilization (IVF) [1,2]. It is unknown whether these facts are closely related. Although it is impossible to simply compare the results of IVF and ICSI due to the difference in their indications, it has been determined that pregnancy rates, the endpoint of fertilization failure treatment, are similar between ICSI and IVF treatments. This is because negative impacts of ICSI on fertilization do not become apparent due to a considerable effect of the in vitro culture environment. In this report, we discuss causes for the low development rate of the blastocyst after ICSI.","PeriodicalId":126001,"journal":{"name":"Reproductive Immunology and Biology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122807311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In human pregnancy, this system takes an important role on trophoblast invasion, spiral artery remodeling and the maintenance of the course of pregnancy. In this review, we describe roles of proteases (matrix metalloproteinases, plasminogen activators and inhibitors) in early pregnancy, especially on placentation. A radical switch of the placentation process from invasive trophoblast invasion (until 10w GA) to spiral artery remodeling (12 to 15w GA, which now regarded as a key pathophysiology of the complicated human pregnancy if it failed) is considered to be owe to the protease system alteration on invasive trophoblast and uterine natural killer cells. Further research into protease system in human reproduction is needed for understanding of mysterious establishment of early human pregnancy.","PeriodicalId":126001,"journal":{"name":"Reproductive Immunology and Biology","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124380030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
