Background: Reproductive outcomes after fresh in vitro fertilization/intracytoplasmic sperm injection–embryo transfer (IVF/ICSI–ET) cycles are diverse in infertile women with a history of ovarian cystectomy for endometriomas. We aimed to de…

Abstract Background : Recent studies have confirmed that endometriosis is a chronic inflammatory disease. In our previous work, we found that STING (stimulator of interferon genes) was differentially expressed in eutopic endometrium and con…

Background: The association between endometriosis and embryological outcomes remains uncertain. The meta-analysis aimed to evaluate the impact of endometriosis on embryo quality. Methods: A systematic review and meta-analysis was conducted …

ObjectiveThis study was performed to quantify hidden blood loss (HBL) and explore its influential factors in myomectomy.MethodsTwo hundred nine patients who underwent myomectomy by laparotomy or laparoscopy from 1 January 2017 to 31 Decembe…

AimEndometriosis is associated with infertility. The aim of this study was to examine the overall proteomic changes of eutopic endometrium in infertile women with endometriosis.MethodsTandem mass tags combined with multidimensional liquid c…

Purpose: The aim of this study was to investigate the effect of human chorionic gonadotropin (hCG) in hormone replacement (HT) regime for frozen thawed embryo transfer in women with endometriosis (EM). Methods: We performed a retrospective,…

Abstract Purpose To investigate the effect of hCG in hormone replacement regime for frozen thawed embryo transfer in women with endometriosis. Methods We performed a retrospective, database-searched cohort study. The data of endometriosis p…

ObjectiveTo evaluate fertility intensions among couples in Shanghai under the novel coronavirus infection (COVID-19) pandemic against the backdrop of persistently low fertility.MethodsA cross-sectional study was carried out using data from …

Objective: To explore the relationship between different types of female reproductive system dysplasia and age of visit, clinical manifestations, common types of combined malformations and endometriosis. Methods: The patient's medical recor…

During a minimally invasive tumor resection procedure, it is still a challenge to rapidly and accurately trace tiny malignant tumors in real time. Fluorescent molecular imaging is considered an efficient method of localizing tumors during s…

BACKGROUND: Endometriosis is thought to affect the effectiveness of ART by an increased risk of miscarriage. We aimed to investigate the impact of endometriosis in women achieving singleton pregnancies through IVF fresh cycles and risk of m…

Fibrotic tissue may contribute to the origin of some endometriosis-related symptoms, such as chronic pelvic pain and infertility. Alterations in the H19/miR-216a-5p/ACTA2 pathway may mediate the regulation of eutopic endometrial stromal cel…

BackgroundFemale reproductive tumors are common with high morbidity and mortality worldwide; however, the association between gynecological tumors and serum vitamin D is controversial. The aim of this meta-analysis was to evaluate the relat…

BackgroundDifferentially expressed microRNAs (miRNAs) and their target mRNAs may lead to alterations in normal physiological status of the tissues and initiate pathological processes. The aim of this study was to investigate the expression …

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…

AIM: To study whether infertile patients with endometriosis have a higher prevalence of endometrial polyps, and to clarify the characteristics of the pathology of combined polyps. METHODS: Infertile patients who had undergone both hysterosc…

BACKGROUND: Melatonin is a potential therapeutic agent for endometriosis, but its molecular mechanism is unclear. Here, we investigated the effect of melatonin on the epithelial-mesenchymal transition (EMT) in endometriotic endometrial epit…

ObjectiveTo evaluate the effects of different treatment methods for previous ectopic pregnancies (EP) on cryopreserved embryo transfer (CET) outcomes.Materials and methodsThis was a retrospective cohort study. Patients with EP histories wer…

Low progesterone levels are associated with luteal phase deficiency in women with polycystic ovary syndrome (PCOS). The mechanisms regulating progesterone biosynthesis in the granulosa cells from women with PCOS is largely unknown. Fractalk…

Polymorphisms in the Xba I and Pvu II restriction enzyme recognition sites in the estrogen receptor-alpha gene (ESR1) have been associated with multiple diseases, including osteoarthritis. To determine whether such polymorphisms are associa…

AIMS: To study the effect of adenomyosis on in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes in infertile patients. METHODS: We performed a retrospective, database-searched cohort study based on 10,268 patients un…

The aim of this study was to investigate the role of microRNA-21 (miR-21) in the regulation of phosphatase and tensin homolog deleted from chromosome-10 (PTEN) expression and proliferation of endometrioid endometrial cancer (EEC) cells. We …
