Inadequate endometrial receptivity may be responsible for the low implantation rate of transferred embryos in in vitro fertilization (IVF) treatments. Patients with repeated implantation failure (RIF) impact the clinical pregnancy rate for …

BACKGROUND: This cross-sectional study aimed to evaluate the levels of tumor necrosis factor-alpha (TNF-ɑ), interleukin-8 (IL-8), interleukin-6 (IL-6), and transforming growth factor-beta 1 (TGF-β1) in patients with primary and secondary tu…

The present study aimed to investigate the effects of human umbilical cord mesenchymal stem cells (Huc‑MSCs)‑derived exosomes on the migratory abilities of endometrial glandular epithelial cells, and to evaluate the underlying mechanism fro…

AIM: To compare the expression of estrogen receptor α (ERα), Bcl-2 and NF-κB P65 in endometrial polyps from patients with and without endometriosis. METHODS: Immunohistochemistry was used to characterize the expression of ERα, Bcl-2 and NF…

BACKGROUND: With increasing cases of iatrogenic premature ovarian insufficiency (POI), more clinicians are required to counsel patients regarding the gonadotoxic effects of iatrogenic treatments. This survey aimed to explore obstetricians a…

Endometriosis is a common, chronic and painful disease in women, whose pathogenesis remains not entirely clear. Long non-coding RNA (lncRNA) MALAT1 participates in the development of endometriosis. This study further investigated the regula…

Long noncoding RNAs (lncRNAs) modulate endometriosis. The current study investigated the mechanisms and effects of SNHG4 on endometriosis. The qRT-PCR was conducted to examine the miR-148a-3p and SNHG4 expressions in endometriosis tissues. …

BackgroundEctopic pregnancy (EP) is a serious complication of assisted reproductive technology (ART). However, there is no acknowledged mathematical model for predicting EP in the ART population.ObjectiveThe goal of the research was to esta…

Biotransformation is important in the metabolism of endobiotics and xenobiotics. This process comprises the activity of phase I and phase II enzymes. Estrogen sulfotransferase (SULT1E1 or EST) is a phase II conjugating enzyme that belongs t…

BACKGROUND: Whether patients receive low-value hospital care (care that is not expected to provide a net benefit) may be influenced by unmeasured factors at the hospital they attend or the hospital's Local Health District (LHD), or the pati…

The objective of our research was to confirm the prediction role of Grobman model for vaginal birth after cesarean (VBAC) in Chinese pregnant women. In this research, 535 pregnant who had once cesarean delivery and the least once subsequent…

PURPOSE: To assess the elasticity of the pelvic floor muscle (PFM) affected by deep infiltrating endometriosis (DIE) with transperineal elastography. METHODS: This prospective observational study included 88 patients who were diagnosed wit…

BACKGROUND: Improvements in vitrification and frozen embryo transfer (FET) technologies have rapidly increased, and some evidence suggests that FET may increase pregnancy rates and lead to more favourable perinatal outcomes. However, the ou…

PURPOSE: Adenomyosis has a negative impact on female fertility. GnRH agonist treatment can improve pregnancy outcomes in women with adenomyosis. However, the impact of GnRH agonist upon endometrium receptivity of patients with adenomyosis r…

PURPOSE: Adenomyosis is a common, benign gynecological condition of the female reproductive tract characterized by heavy menstrual bleeding and dysmenorrhea. Gonadotropin-releasing hormone (GnRH) agonists are one of the medications used in …

Triclosan (TCS) is a broad-spectrum antimicrobial agent that is frequently used in pharmaceuticals and personal care products. Reports have shown that TCS is a potential endocrine disruptor; however, the potential effects of TCS on placenta…

BACKGROUND: Of all human cancers, gastric carcinoma is the one of the leading causes of death. Helicobacter pylori is considered a major etiologic agent of this disease. Spontaneously occurring gastric carcinoma is a rare diagnosis in nonhu…

OBJECTIVES: To evaluate the safety of ultrasound-guided high-intensity focused ultrasound (HIFU) ablation for patients with diffuse adenomyosis. METHODS: This was a retrospective cohort study. The data was collected from 417 symptomatic ad…

Endometriosis is a chronic, inflammatory and common gynaecological disease. This study investigated the association between TP53 codon 72 polymorphism and the risk of endometriosis. A search for relevant articles was conducted in PubMed, Em…

PURPOSE: Mucin-1(MUC1), a type of glucoprotein, has various expression statuses on the endometrium at different menstrual phases. Normal expression of MCU1 is closely related to successful blastocyst implantation. MUC1 was synthesized and s…

Endometriosis is a complex and challenging disease that involves aberrant adhesion, growth, and progression of endometrial tissues outside of the uterine cavity, and there is evidence to suggest that estrogen plays a key role in its develop…

Human ectopic pregnancy (EP) is a leading cause of pregnancy-related death, but the molecular basis underlying the onset of tubal EP is largely unknown. Female Dicer1 conditional knockout mice are infertile with dysfunctional Fallopian tube…

Some studies have shown that long-term gonadotropin-releasing hormone (GnRH) agonist administration before in vitro fertilization/intracytoplasmic sperm in infertile women with endometriosis or adenomyosis significantly increases the chance…

17β-estradiol, acting through estrogen receptors α and β, plays a fundamental role in the regulation of Fallopian tube cell homeostasis and in the modulation of normal tubal physiological processes. Fluctuations in E2 levels also play cruci…
