BACKGROUND: Insulin resistance has been linked to adverse reproductive and pregnancy outcomes. The triglyceride glucose-body mass index (TyG-BMI) serves as a simple and cost-effective surrogate marker of insulin resistance. This study aimed…

BACKGROUND: Euploid miscarriage may indicate underlying non-genetic factors in the couples. This study aimed to investigate the subsequent live birth rates in women with a prior euploid or aneuploid sporadic miscarriage (SM) in assisted rep…

BACKGROUND: The endometrial preparation of frozen embryo transfer cycle is to synchronize of endometrium and embryo under the condition of exogenous estrogen and progesterone drugs in HRT or follicle monitoring in NC. Estrogen and progester…

OBJECTIVE: To evaluate the live birth rate (LBR) of assisted reproductive technology (ART) treatment using vitrified donated oocytes in China and to investigate the influencing factors on live birth outcomes. METHODS: This retrospective co…

PURPOSE: Monitoring early human chorionic gonadotropin (hCG) levels is crucial for predicting pregnancy outcomes in anxious couples undergoing assisted reproductive technology. The aim of this study was to compare subsequent reproductive ou…

RESEARCH QUESTION: While growth hormone (GH) is hypothesized to potentially enhance embryo quality, results of current basic and clinical researches remain inconclusive. This study assesses the effect of GH supplementation on embryo quality…

BACKGROUND: To compare in-vitro fertilization and embryo transfer (IVF-ET) pregnancy outcomes following endometrial polypectomy using either a manual mechanical hysteroscopic tissue resection device (mHTR) or traditional mechanical resectio…

BACKGROUND: The global health crisis of coronavirus disease 2019 (COVID-19) continues to impact people of all age groups worldwide. Recent studies increasingly support that COVID-19 infection may affect reproductive function, causing subfer…

BACKGROUND: High rates of infertility and pregnancy complications in patients with intrauterine adhesion (IUA) even after surgical repair may be associated with poor endometrial receptivity (ER). In our previous study, we found that changes…

INTRODUCTION: With ongoing global lifestyle changes and economic development, the prevalence of hyperuricemia has steadily increased. Elevated levels of serum uric acid (SUA) have been linked to gestational diabetes mellitus (GDM); however,…

Advanced maternal age (AMA, ≥35 years) women undergoing assisted reproductive technology (ART) face reduced live birth rates (LBR) and remain a major clinical challenge. In a large randomized trial, Zishen Yutai Pill (ZYP) improved LBR in t…

INTRODUCTION: Ultrasound has become a routine method for endometrial receptivity (ER) evaluation. However, there is controversy over the independent evaluation values of various ultrasound indicators. Some researchers have designed multi-in…

STUDY OBJECTIVE: To investigate whether different timings of GnRH-a downregulation affected assisted reproductive outcomes in infertile women with moderate-to-severe intrauterine adhesions (IUAs) accompanied by adenomyosis. DESIGN: A retro…

AIMS: To assess the predictive value of estradiol (E2) related parameters on the incidence of gestational diabetes mellitus (GDM) in women undergoing fresh embryo transfer. MATERIALS AND METHODS: A Post-hoc analysis of a prospective cohort…

OBJECTIVES: Our study tries to investigate the effect of the Mediterranean diet (MeDiet) on assisted reproductive treatment outcomes in women after COVID-19 infection. DESIGN: A prospective observational cohort study in the Reproductive an…

BACKGROUND: Simnotrelvir is an oral 3-chymotrypsin-like protease inhibitor that has been found to have in vitro activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and potential efficacy in a phase 1B trial. METHO…

BACKGROUND: To explore whether SARS-CoV-2 infection affects the pregnancy outcomes of assisted reproductive techniques (ART). METHODS: A prospective cohort study recruited patients for embryo transfer from December 01, 2022, to December 31…

OBJECTIVE: To clarify whether intrauterine adhesions (IUAs) affect endometrial receptivity (ER) on the day of ovulation and to compare patients with mild and moderate-severe adhesions. METHODS: This prospective cohort study included 592 in…

BACKGROUND: Vitamin D binding protein (DBP) might increase substantially after ovarian stimulation and hence could be associated with IVF/ICSI outcomes because it determines the fraction of free bioavailable 25(OH) vitamin D. In this study,…

BACKGROUND: For infertile women with overweight/obesity and insulin resistance (IR), it is uncertain whether intervention before infertility treatment can improve live birth rate (LBR). We implemented a factorial-design study to explore the…

PURPOSE: To evaluate whether outcomes of in vitro fertilization (IVF) are affected during the coronavirus disease-19 (COVID-19) pandemic. METHODS: This was a single-center, retrospective study. Embryo development, pregnancy, and live birth…

OBJECTIVE: To obtain quantitative and comprehensive results of the changes in comprehensive ER indicators from ovulation day to transplantation day by ultrasonography during the natural frozen-thawed embryo transfer cycle (FET). METHODS: T…

BACKGROUND: Preimplantation genetic testing for aneuploidy (PGT-A) is widely used as an embryo selection technique in in vitro fertilization (IVF), but its effectiveness and potential beneficiary populations are unclear. METHODS: This retr…

OBJECTIVE: To evaluate the clinical availability and stability of histological endometrial dating as a tool for personalized frozen-thawed embryo transfer (pFET) in patients with repeated implantation failure (RIF) in natural cycles. METHO…

BACKGROUND: The current routine endometrial preparation protocol for women with polycystic ovary syndrome (PCOS) is hormone replacement treatment (HRT). Letrozole is rarely used in frozen embryo cycles. Evidence confirming whether letrozole…
