Retracted: Endometrial scratch injury in infertile women seeking conception through natural or intrauterine insemination cycles: A systematic review and meta‐analysis

Abstract

Implantation is the attachment of the developing embryo to the uterine wall followed by its penetration to the maternal circulatory system to form the future placenta. 1 The embryo invades the endometrium completely only in great apes and humans. Implantation is restricted in both time and space. This implantation window begins 2-3 days after the fertilized ovum reaches

Biomedical Innovation in Fertility Care

“…This procedure, rated amber on the Human Fertilisation and Embryology Authority (HFEA) rating system, has been very popular over the last years worldwide (Lensen et al, 2016;Palomba et al, 2023b). Various reviews and meta-analyses (Maged et al, 2023;Palomba et al, 2023a;van Hoogenhuijze et al, 2023), including a Cochrane review (Lensen et al, 2021a), underline that it is unclear whether this procedure increases the chance of implantation and live birth and, if so, for whom, and how the scratch should be performed. Beside the uncertainty regarding its effectiveness, concerns have been raised due to the similar weakness in the quality of evidence both for and against ES.…”

Immune Cell Functionality during Decidualization and Potential Clinical Application

“…For a more detailed insight, many reviews and meta-analytic publications were published concerning this topic, which seems to be declining but is still under a heated debate (reviewed i.a. in [ 171 , 172 , 173 , 174 , 175 , 176 , 177 , 178 ]).…”
