PURPOSE OF REVIEW: Since its first description in 2003, the endometrial scratching procedure has been the topic of over 1000 studies. This procedure, used to improve endometrial receptivity for assisted reproduction, is accessible - any gynecologist can easily perform it - and has been adapted into clinical routine by some reproductive units. However, the available data are controversial, and no biological plausibility exists to support the use of this intervention. This study aims to critically review the existing data, focusing on the last 2 years, regarding the efficiency of endometrial scratching...

PURPOSE: Lipocalin 2 (LCN2) is a secretory protein that is involved in various physiological processes including iron transport. We previously identified LCN2 as an up-regulated gene in endometrial carcinoma, and found that the overexpression of LCN2 and its receptor, SLC22A17, was associated with a poor prognosis. However, the functions and mechanism of action of LCN2 currently remain unclear. METHODS: The LCN2-overexpressing endometrial carcinoma cell lines, HHUA and RL95-2, and LCN2-low-expressing one, HEC1B, were used...

BACKGROUND: The success rate of infertility treatments remains modest. Endometrial injury has been suggested as an intervention to increase the probability of pregnancy in women undergoing assisted reproductive technologies such as in vitro fertilisation (IVF). The majority of studies and systematic reviews have reported that endometrial injury improves the outcomes of IVF, intrauterine insemination and natural conception; however, the size and quality of the studies are poor. The low quality of the available evidence questions the presence of any real beneficial effect, and the applicability of the intervention in different populations remains unclear...

PURPOSE OF REVIEW: To review updated information on the influence of endometrial scratching on IVF. RECENT FINDINGS: Endometrial receptivity remains an important rate-limiting step affecting the success of IVF. The current evidence on the effect of endometrial scratching on IVF ranges from marked improvement, no difference to a potentially negative impact. The heterogeneity of studies presents a challenge in interpretation of data for routine clinical practice. SUMMARY: Endometrial scratching performed in the preceding cycle is associated with improved clinical pregnancy and live birth rates in women with recurrent implantation failure, but not in unselected subfertile women undergoing IVF...
