The outcomes of in vitro fertilization (IVF) for endometriotic women are significantly worse than for patients without ovarian endometriosis (OEM), as shown by fewer retrieved oocytes. However, the exact pathophysiological mechanism is stil…

Endometriosis (EMs) is a common gynecological disease whose pathogenesis remains unclear. Immunological factors have been a key hotspot in recent years. Peritoneal fluid samples from women with EMs show defectively activated macrophages (MΦ…

OBJECTIVES: The aim of this study was to investigate the impact of a history of recurrent ectopic pregnancy (EP) on pregnancy outcomes of subsequent in vitro fertilization (IVF) treatment. METHODS: A retrospective cohort study involving 45…

The cause of endometriosis, which is characterized by the existence of functional endometrial tissue outside the uterine cavity, is poorly understood. Seminal plasma (SP) is rich in multiple cytokines that may promote endometrial tissue sur…

The pathological expression and function of lactate dehydrogenase A (LDHA), a key enzyme that converts pyruvate into lactic acid during glycolysis, remains unknown in endometriosis. In the present study, LDHA expression in tissue samples wa…

This study investigates the effect of 2 laparoscopic methods on ovarian reserve in patients of reproductive age with endometriomas.This was a retrospective study performed at a tertiary medical center from Jan 1st to Dec 31st, 2016. Laparos…

The implantation rate (IR) in assisted reproductive technologies such as in vitro fertilization (IVF) and intracytoplasmic sperm injection is affected by many different factors such as age, quality of embryo, and stage of embryo development…

BACKGROUND: Unresponsive thin endometrium caused by Asherman syndrome (AS) is the major cause of uterine infertility. However, current therapies are ineffective. This study is to evaluate the effect of transplantation with collagen scaffold…

PURPOSE: To examine the expression of MUC16 in the endometrium peri-implantation period in three different cohort studies. METHODS: This was a retrospective observational cohort study. A total of 245 participants were recruited in three se…

Endometriosis an important cause of female infertility and seriously impact physical and psychological health of patients. Endometriosis is now considered to be a public health problem that deserves in-depth investigation, especially the et…

The NOD-like receptor protein 3 (NLRP3) inflammasome is a key regulator of the host's immune response, and many immune and metabolic disorders are linked to its activation. This review aimed to investigate and clarify the relationship betwe…

Abstract Background: The cause of endometriosis, which is characterized by the existence of functional endometrial tissue outside the uterine cavity, is poorly understood. Seminal plasma (SP) is rich in multiple cytokines may promote endom…

This study means to investigate a combination of noninvasive methods in diagnosis of minimal or mild endometriosis expecting to narrow down the range of laparoscopic exploration for female infertility.It is a retrospective case control stud…

Endometriosis is associated with benign but adversely developed cysts in the extrauterine environment. The oxidative imbalanced environment induces DNA damage and affects cell cycle progression of endometrial stromal cells (ESCs) and endome…

Multiple studies have confirmed that human menstrual blood-derived stem cells (MenSCs) have potential applications in regenerative medicine or cell therapy. However, the contribution of MenSCs to endometrial repair is currently unknown. We …

Hypoxia plays a vital role in the progression of endometriosis. Additionally, integrin-mediated aberrant adhesion is also essential for establishment of endometriotic lesions. In this study, we sought to determine the function of hypoxia in…

OBJECTIVE: Ovarian fibrosis is characterized by excessive proliferation of ovarian fibroblasts and deposition of extracellular matrix (ECM) and it is one of the principal reasons for ovarian dysfunction. This review aimed to investigate the…

Gonadotropin-releasing hormone agonist (GnRH-a) was one of the most used therapies in the treatment of endometriosis. But unfortunately, no literatures realized GnRH-a may be related to thrombosis until now. The case below was exactly about…

STUDY QUESTION: Are endometriotic mesenchymal stem cells (Ecto-MSCs) involved in the fibrosis of ovarian endometrioma? SUMMARY ANSWER: Ecto-MSCs enhanced the fibrotic behavior of stromal cells in ovarian endometrioma through the Wnt/β-cate…

OBJECTIVE: To investigate the relationship between endometrial expressions of angiogenic factors around the time of embryo implantation and P level before oocyte retrieval during IVF-ET treatment. DESIGN: Retrospective study. SETTING: Uni…

PURPOSE: This study aimed to compare slow freezing (SF) and vitrification (VT) techniques for day 3 embryo cryopreservation in infertile couples. METHODS: This retrospective cohort study enrolled 5613 infertile patients, with 7862 frozen-t…

PURPOSE: The study was designed to evaluate whether cumulus cell removal 4 h post-insemination could influence fertilization and embryo quality. METHODS: The study included 61couples undergoing standard long down regulation protocol from J…

BACKGROUND: Endometriosis affects natural fertility through various approaches, and in vitro fertilization (IVF) is a good treatment. But the IVF result of endometriosis patients is still under debate. We investigated the effect of endometr…
