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.

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, 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.

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.

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.

The process of implantation is a dynamic, complex reciprocal interaction between the embryo and uterus. The major events of this process include synchronized development of the preimplantation embryo into an implantation-competent blastocyst with preparation of the uterus to the receptive state, attachment of the blastocyst to the uterine luminal ...

Endothelins and their receptors in embryo implantation
Journal of Cellular Biochemistry, 2019AbstractAs a critical stage of pregnancy, the implantation of blastocysts into the endometrium is a progressive, excessively regulated local tissue remodeling step involving a complex sequence of genetic and cellular interplay executed within an optimal time frame. For better understanding the causes of infertility and, more importantly, for developing

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 ...
