Determinants of Embryo Implantation: Roles of the Endometrium and Embryo in Implantation Success

Reproductive Sciences, 2023
Both 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, 1998
The 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.

MicroRNA and Embryo Implantation

American Journal of Reproductive Immunology, 2015
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

Uterine contractility and embryo implantation

Current Opinion in Obstetrics & Gynecology, 2005
The aim of this article is to assess the importance of uterine contractility in the implantation of human embryos.Recent findings show that the receptive phase of the endometrium seems to occur in close association with the appearance of pinopodes and endometrial integrins that may be activated by the IL-1 system.

Number of Embryos Transferred and Implantation

Annals of the New York Academy of Sciences, 2004
Abstract: 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.

Chocolate and Embryo Implantation [PDF]

Homoeopathic Links, 2015
Two infertile women in whom five apparently normal embryos formed by in vitro fertilisation (IVF) had failed to implant were treated with the homeopathic medicine Chocolate. Both women successfully implanted the next IVF embryo and gave birth to daughters.

Role of Aneuploidy on Embryo Implantation

Gynecologic and Obstetric Investigation, 2007
Approximately 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.

Lipid signaling in embryo implantation

Prostaglandins & Other Lipid Mediators, 2005
A 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.

Embryo-uterine interaction in implantation

Life Sciences, 1980
Abstract 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 ...
