Determinants of Embryo Implantation: Roles of the Endometrium and Embryo in Implantation Success
Reproductive Sciences, 2023Both uterine endometrium and embryo contribute to implantation success. However, their relative role in the implantation success is still a matter for debate, as are the roles of endometrial receptivity analysis (ERA), endometrial scratch (ES), endometrial microbiome, and intrauterine or intravenous measures that are currently advocated to improve the ...

Cytokines and embryo implantation
Journal of Reproductive Immunology, 1998The implantation process is currently considered the most relevant limiting factor for successful pregnancy. It is evident that molecular interactions at the embryo-maternal interface at the time of implantation are crucial in order to understand the mechanisms of embryonic implantation.

Number of Embryos Transferred and Implantation
Annals of the New York Academy of Sciences, 2004Abstract: Multiple pregnancies are considered the most frequent and serious complication of assisted reproduction technology. To reduce the frequency of multiple pregnancies, several centers have adopted a policy of reducing the number of embryos transferred in the uterus, suggesting single embryo transfer.

Micro
ProblemIn mammals, implantation involves interactions between an activated blastocyst and a receptive endometrium. There are controversies on the role of microRNAs in preimplantation embryo development. The actions of endometrial microRNAs on implantation are beginning to be understood.Method of StudyReview of literature on microRNAs in preimplantation

Current Opinion in Obstetrics & Gynecology, 2013
Implantation is an essential step in the development of a pregnancy, but often fails in humans. In assisted reproductive technologies, implantation failure continues to impair treatment outcomes, with distressing results for patients and physicians.Morphokinetics, comprehensive chromosome screening, and the analysis of embryo-derived products ...

Lipid signaling in embryo implantation
Prostaglandins & Other Lipid Mediators, 2005A reciprocal interaction between the implantation-competent blastocyst and the receptive uterus is required for successful implantation. Although various molecular pathways are known to participate in this cross-talk, a comprehensive understanding of the implantation process is still missing.

Role of Aneuploidy on Embryo Implantation
Gynecologic and Obstetric Investigation, 2007Approximately 30% of oocytes in the human species carry a chromosomal imbalance. This condition has severe clinical consequences as approximately one-third of spontaneous abortions are aneuploid. The most obvious link to the increase of aneuploidy in oocytes is maternal age. This has been directly confirmed by the analysis of polar bodies.

Embryo-uterine interaction in implantation
Life Sciences, 1980Abstract Pregnant donor (day 3) and non-pregnant recipient rats were hypophysectomized and injected daily for 6 days with 2 mg of progesterone. A single dose of 20 ng of estradiol-17β in saline was administered via a tail vein to either the donor, the recipient, or to both animals; blastocysts were transferred 60 to 90 minutes after the latter ...

Antibodies, implantation and embryo survival
Reproduction, Fertility and Development, 1992The diverse strategies adopted among species for the maintenance of luteal function converge to meet the indispensable requirement for this hormone particularly at the time of onset of implantation. What has emerged from immunization studies is the difference that exists between various species in the effects of progesterone depletion.
