ObjectiveTo compare the clinical outcome of freeze-thawed embryo transfer at different embryonic development days in whole embryo freezing patients of different ages.MethodsThis was a retrospective study. Collected clinical data of 558 pati…

BackgroundZona pellucida (ZP) plays an important role in oocyte development and fertilisation, as well as in early embryo development. However, there is currently no exploration of systematic categorising and clinical treatment measures for…

PurposeThis study investigates the impact of the Chinese New Year (CNY) holiday on frozen embryo transfer (FET) outcomes in assisted reproductive technology (ART), particularly in vitro fertilization (IVF). Previous research has highlighted…

ObjectiveTo evaluate the impact of endometrial thickness (EMT) variations on clinical outcomes in two distinct ovarian stimulation protocols: the early-follicular long-acting GnRH agonist protocol and the midluteal short-acting GnRH agonist…

ObjectiveAs a common endocrine and metabolic disorder, polycystic ovary syndrome (PCOS) is mostly associated with an obese phenotype. The present research focuses on the clinical significance of miR-379 in obesity-PCOS and attempts to eluci…

ObjectiveTo compare the pregnancy outcome of the fresh cycle or freeze-thaw cycle embryo transfer of patients treated with a long follicular phase regimen and antagonist regimen, and explore the clinical therapeutic effect of the two regime…

PurposeTogether with ultrasound measurement of follicle size, serum estradiol (E2) provides guidance for controlled ovarian hyperstimulation (COH). However, during the COH process, some patients experience decreased serum E2 level, especial…

BackgroundAlthough in vitro fertilization (IVF) in infertile patients with endometrial hyperplasia is common after drug treatment, the pregnancy outcomes are often unsatisfactory. Till date, no studies have reported the outcome of patients …

ObjectiveTo explore the experiences of patients with ectopic pregnancies with delayed medical care, with the goals to promote timely access to care, reduce subsequent physical and psychological impacts, and provide recommendations for impro…

PurposeTo explore the risk and protective factors for developing ovarian cancer and construct a risk prediction model.MethodsInformation related to patients diagnosed with ovarian cancer on the electronic medical record data platform of thr…

ObjectiveTo investigate whether seasonal variations and meteorological factors influence pregnancy outcomes in women undergoing in vitro fertilization-embryo transfer (IVF-ET) treatment.DesignRetrospective cohort study.SettingUniversity-aff…

BackgroundStudies have shown that abnormalities in the decidualization process were closely related to recurrent implantation failure (RIF). Prokineticin 2 (PK2) is a secreted protein with angiogenic and tissue remodeling functions but its …

BackgroundWe aimed to compare the clinical and perinatal outcomes of patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment with either an early-follicular long…

In a normal pregnancy, maternal circulatory system presents a hypercoagulable state due to the effect of hormone secretion. Even minor variations in fibrinolytic system could lead to hyper- or hypofibrinolysis, affecting placental formation…

BackgroundSubchorionic hematoma (SCH) is common in early pregnancy achieved by in vitro fertilization-embryo transfer/frozen embryo transfer (IVF-ET/FET), and is associated with adverse obstetric outcomes. However, there are no methods know…

ObjectiveTo investigate the results of in vitro fertilization among polycystic ovary syndrome (PCOS) patients using the long-acting long protocol regarding the relationship between menstrual patterns and adverse pregnancy outcomes.DesignRet…

ObjectivesTo compare the appendiceal microbiomes and examine the prevalence of Campylobacter species in the appendices of adult subjects with confirmed acute non-perforated appendicitis and controls with healthy appendices.DesignArchived sa…

ObjectiveTo investigate the effect of seasons on the incidence of high risk of ovarian hyperstimulation syndrome (OHSS) after in oocyte retrieval in patients with polycystic ovarian syndrome (PCOS) and to establish a nomogram to predict the…

OBJECTIVE: To compare the efficacy of postoperative adjuvant treatment (gonadotropin-releasing hormone agonists [GnRHas] and oral contraceptives [OCs]) and expectant treatment in preventing recurrent dysmenorrhea following conservative lapa…

RESEARCH QUESTION: Which factors are related to early spontaneous miscarriage in IVF-conceived clinical pregnancies? DESIGN: A total of 21,485 clinical pregnancies were included in the analysis. First, early spontaneous miscarriage rates w…

This study was aimed to explore the correlation between catechol-O-methyltransferase (COMT) gene polymorphisms and endometriosis susceptibility in Chinese Han population.This case-control study recruited 134 endometriosis patients and 139 h…

To explore the role of hScrib in the pathogenesis of endometriosis.This was a retrospective study of 240 women in our hospital between January 2014 and January 2017. The expression of hScrib in endometrium (EM), endometriosis (EMs), and end…

This study investigated the risk factors and early predictors for heterotopic pregnancy (HP) after in vitro fertilization and embryo transfer (IVF-ET). From January 2008 to January 2013, 41 cases of HP and 72 cases of intrauterine twin preg…

Many protocols have been proposed to improve IVF outcomes for poor ovarian responders. The aim of this study was to explore the relationship between age, ovarian hyperstimulation protocol and IVF/ICSI outcomes in poor ovarian responder (POR…

In order to explore the relationship between serum progesterone (P) level on the day of human chorionic gonadotrophin (HCG) administration and cumulative live birth rate in patients with different ovarian response during in vitro fertilizat…
