Repeated implantation failure versus repeated implantation success: discrimination at a metabolomic level [PDF]
Human Reproduction, 2016 Is there any difference at the serum metabolic level between women with recurrent implantation failure (RIF) and women with recurrent implantation success (RIS) when undergoing in vitro fertilization (IVF)?Eight metabolites, including valine, adipic acid, l-lysine, creatine, ornithine, glycerol, d-glucose and urea, were found to be significantly up ...

Options for overcoming implantation failures in infertility of uterine genesis due to chronic endometritis. A review [PDF]
Гинекология, 2022 Chronic endometritis remains one of the most controversial issues of modern gynecology. The high relevance of research in this area is confirmed not only by the high prevalence but also by the extremely negative impact of this disease on the reproductive

Research progress on effect of hydrosalpinx on pregnancy outcomes and treatment strategies [PDF]
Xin yixue, 2022 Hydrosalpinx is one of the causes of repeated embryo implantation failures in assisted reproductive technology. It is generally considered that mechanical washout, reduced endometrial receptivity, and toxic effects of hydrosalpinx on the embryos are the ...

Assessment and treatment of repeated implantation failure (RIF) [PDF]
Journal of Assisted Reproduction and Genetics, 2012 Repeated implantation failure (RIF) is determined when embryos of good quality fail to implant following several in vitro fertilization (IVF) treatment cycles. Implantation failure is related to either maternal factors or embryonic causes. Maternal factors include uterine anatomic abnormalities, thrombophilia, non-receptive endometrium and ...
