The success of assisted reproduction, although gradually increasing over the years, is still less than satisfactory. Many couples have benefited from this treatment; many have also been left frustrated following multiple failed attempts (Bulent Urman et al. 2005). Repeated implantation failure (RIF), defined as three or more failed IVF attempts or failure of IVF after cumula- Abstracts of the 5...
Failure of embryo implantation is a major limiting factor in early pregnancy and assisted reproduction. Determinants of implantation include the embryo viability, the endometrial receptivity, and embryo-maternal interactions. Multiple molecules are involved in the regulation of implantation, but their specific regulatory mechanisms remain unclear. MicroRNA (miRNA), functioning as the transcript...
in this paper pre-implantation embryo from the viewpoint of civil liability of the medical group, third parties, effect of conditions of contract on change of civil liability and blood money will be discussed. the islamic jurists and lawyers have investigated all of them from the viewpoint of lawfulness and unlawfulness of this case itself, the method of creation and transfer and its jurisprude...
The normal intrauterine fluid environment is essential for embryo implantation. In hydrosalpinx patients, the implantation and pregnancy rates are markedly decreased after IVF-embryo transfer, while salpingectomy could significantly improve the pregnancy rates. The leakage of hydrosalpinx fluid into the endometrial cavity was supposed to be the major cause for impaired fertility. However, the u...
Embryo implantation is essential for mammalian pregnancy, which involves intricate cross-talk between the blastocyst and the maternal endometrium. Recent advances have identified various molecules crucial to implantation and endometrial receptivity, including leukemia inhibitory factor, calcitonin, and homeobox A10. There is a close relationship between implantation and inflammation. Lipoxins, ...
Objective The primary objective of the study was to compare baseline KP levels in females with different causes of infertility and then correlate it with the risk of failure to conceive, preclinical abortion and pregnancy after intracytoplasmic sperm injection (ICSI). MaterialsAndMethods AA longitudinal cohort study was carried out from August 2014 till May 2015 recruiting one hundred and twent...
The molecular basis of embryo-maternal relationship, that leads to proper implantation into a receptive maternal endometrium to successfully establish a pregnancy, is still not fully understood. The human endometrium undergoes morphological and hormonal changes during the menstrual cycle in preparation for successful embryo implantation, or menstrual shedding in the absence of implantation. The...
BACKGROUND Embryo implantation is crucial for animal reproduction. Unsuccessful embryo implantation leads to pregnancy failure, especially in human-assisted conception. Environmental factors have a profound impact on embryo implantation. Because people are being exposed to more light at night, the influence of long-term light exposure on embryo implantation should be explored. METHODS The eff...
the success rate of several advanced basic and clinical techniques in the field of mammalian biotechnology, including cloning, pre-implantation genetic diagnosis, and assisted reproductive techniques (art) depends mainly on the success rate of pregnancy following in vitro fertilization-embryo transfer (ivfet). the techniques used in art have advanced considerably since the first in vitro fertil...
Failure of the human embryo to implant into the uterine wall during the early stages of pregnancy is a major cause of infertility. Implantation involves embryo apposition and adhesion to the endometrial epithelium followed by penetration through the epithelium and invasion of the embryonic trophoblast through the endometrial stroma. Although gene-knockdown studies have highlighted several molec...
