OBJECTIVE: To assess whether endometrial injury in the cycle preceding controlled ovarian hyperstimulation during intracytoplasmic sperm injection (ICSI) improves the implantation and pregnancy rates. METHODS: Between January 1, 2016, and March 31, 2017, a randomized controlled trial was conducted at a center in Egypt among 300 women who met inclusion criteria (first ICSI cycle, aged <40 years, day-3 follicle-stimulating hormone <10 IU/L, normal serum prolactin, no uterine cavity abnormality)...

OBJECTIVES: To determine the implantation success of local endometrial injury in patients undergoing intrauterine insemination following ovulation induction with gonadotropins as an infertility treatment. MATERIAL AND METHODS: In this prospective randomized controlled trial, ovulation induction was performed with gonadotropins in 80 patients following intrauterine insemination. In 40 patients, local endometrial injury (scratch) was performed in the midluteal phase of the cycle preceding ovarian stimulation with a Novak curette to the posterior side of the endometrial cavity...

OBJECTIVE: To explore the expression level of Nrf2 in adenomyosis and study the mechanism of abnormal expression of Nrf2 in the pathogenesis of adenomyosis. METHODS: Western blot, immunohistochemistry(IHC) and real time PCR were used to measure Nrf2 expression levels in tissue and cell samples. Knockdown and overexpression of Nrf2 were used to investigate the variation of migration ability of endometrial glandular cells as well as the regulatory mechanism. RESULTS: Nrf2 protein levels were significantly higher in the eutopic and ectopic endometrial glands when compared with control cases using IHC and western blot methods...

BACKGROUND: Success rates of assisted reproductive techniques (ART) are approximately 30%, with the most important limiting factor being embryo implantation. Mechanical endometrial injury, also called 'scratching', has been proposed to positively affect the chance of implantation after embryo transfer, but the currently available evidence is not yet conclusive. The primary aim of this study is to determine the effect of endometrial scratching prior to a second fresh in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycle on live birth rates in women with a failed first IVF/ICSI cycle...

AIM: Endometrial scratch injury (ESI) has been recently proposed to enhance the implantation rate in assisted reproductive technology cycles. The present study was conducted to determine the effect of ESI on pregnancy rate in women with intrauterine insemination (IUI) failure. METHODS: This prospective randomized controlled study was carried out in Imam-Khomeini Hospital and Royan Institute, Tehran, during a 12-month period from January 2013 to January 2014. After assessment, 169 patients who had IUI failure twice or more (no chemical or clinical pregnancy) with normal uterine anatomy and hysterosalpingography, were enrolled...

PURPOSE: To study the effect of endometrial scratching in infertile couples undergoing ovulation induction and intrauterine insemination (IUI) cycles. METHODS: A prospective randomized controlled trial was conducted in the Department of Obstetrics and Gynaecology, AIIMS, New Delhi, India. One hundred forty-four women with primary/secondary infertility were recruited. Couples were either unexplained or male factor infertility. Subjects were randomized into intervention (scratching) and control group...

The benefit of endometrial scratch (ES) prior to embryo transfer is controversial. Systemic analysis has confirmed its potential benefit, especially in women with repeated IVF failures, yet most studies have focused on fresh embryo transfer, and its effect on vitrified-warmed embryo transfer (FET) cycles is yet to be explored. We hereby present our prospective, double-blind, randomized controlled study on the evaluation of the implantation and pregnancy rate after ES prior to natural-cycle FET. A total of 299 patients underwent natural-cycle FET and were randomized to receive ES (n = 115) or endocervical manipulation as control (n = 114) prior to FET cycle, and a total of 196 patients had embryo transfer (93 patients in each group)...

The SerpinE2 pathway is evolutionarily conserved and plays an important role in tumorigenesis. SerpinE2 (a small ubiquitin-related modifier), like ubiquitin, conjugates SerpinE2 proteins onto lysine residues of target proteins. SerpinE2 over-expression has been found in several tumors. Here, we detected the level of SerpinE2 in 72 samples of EC tissue using immunohistochemistry to assess the role of SerpinE2 in EC prognosis. Meanwhile, we knocked down SerpinE2 by siRNA in the HTB-111 and Ishikawa EC cell lines and analyzed the viability and mobility change using an MTT assay, an annexin V/PI apoptosis assay, a wound scratch test and a transwell assay...

Although curcumin shows anti-proliferative and anti-inflammatory activities in various cancers, the effect of curcumin on cellular migration in endometrial adenocarcinoma cells remains to be understood. The current investigation was aimed to explore the anti-proliferative and anti-migratory effects of curcumin and its mechanism of action in endometrial cancer cells. Our in-vitro and in-vivo experimental studies showed that curcumin inhibited the proliferation of endometrial cancer cells and suppressed the tumor growth in Ishikawa xenograft mouse model...

Context: Heavy menstrual bleeding (HMB) is common and incapacitating. Aberrant menstrual endometrial repair may result in HMB. The transforming growth factor (TGF)-β superfamily contributes to tissue repair, but its role in HMB is unknown. Objective: We hypothesized that TGF-β1 is important for endometrial repair, and women with HMB have aberrant TGF-β1 activity at menses. Participants/Setting: Endometrial biopsies were collected from women, and menstrual blood loss objectively measured [HMB >80 mL/cycle; normal menstrual bleeding (NMB) <80 mL]...

OBJECTIVE: To investigate the effect and mechanism of mifepristone on the migration of human endometrial carcinoma cells. METHODS: A human endometrial carcinoma cell line, Ishikawa cells, was cultured in vitro and treated with mifepristone at different concentrations. Wound healing assay was applied to detect the migration of Ishikawa cells. RT-PCR and methylation-specific PCR (MSP) were used to detect the levels of H19 mRNA and its DNA methylation. Western-blot was used to detect the expressions of HMGA2 and epithelial to mesenchymal transition (EMT) related proteins...

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...

OBJECTIVE: To investigate the role of phosphatase of regenerating liver-3 (PRL-3) in the 17β-estradiol (E2)- and interleukin 6 (IL-6)-induced migration of endometrial stromal cells (ESCs) from ectopic endometrium. METHODS: Ectopic endometrial tissues were collected from patients with endometriosis, and PRL-3 expression in ectopic and eutopic endometrium was examined by immunohistochemistry. Endometrial stromal cells isolated from ectopic endometrium were treated with E2, progesterone (P), IL-6, or sodium orthovanadate (Sov) to inhibit PRL-3...

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...
