BACKGROUND: Low birth weight (LBW) significantly influences neonatal prognosis as well as growth and development in adult. This study aimed to explore the increased risk of low birth weight (LBW) in singleton live births in connection with …

ABSTRACT: Low oocyte retrieval (LOR), defined as oocytes retrieved from <50% of mature follicles, significantly impacts IVF success, especially in patients with diminished ovarian reserve (DOR). Predictive models tailored for this populatio…

INTRODUCTION: Acupuncture has been explored as a potential intervention for POR; however, high-quality evidence is limited. This multicenter randomized trial evaluated the effect of acupuncture on the number of oocytes retrieved following c…

INTRODUCTION: Diminished ovarian reserve (DOR) is known to reduce the likelihood of achieving pregnancy or live births in women undergoing in vitro fertilization and embryo transfer (IVF-ET). Acupuncture maybe effective for DOR, but current…

BACKGROUNDS: The study was designed to analyze early pregnancy loss rates in first-time fresh embryo transfer cycles in low prognosis patients according to the POSEIDON criteria. METHODS: This was a retrospective cohort study, including pa…

BACKGROUND: Both intramural myomas and thin endometrium exert a detrimental influence on the outcomes of assisted reproductive technology (ART). The downregulation of gonadotropin releasing hormone agonists (GnRH-a) is regarded as an effect…

OBJECTIVE: This study investigated the impact of blastocyst developmental stage and morphological grading on pregnancy outcomes following single euploid frozen-thawed blastocyst transfer (SE-FBT) in young patients with recurrent pregnancy l…

The present study aimed to explore whether there is an association between the transfer of frozen thawed embryos (FET) obtained during SARS-CoV-2 infection and an increased risk of adverse pregnancy outcomes. We performed a case-control coh…

BACKGROUND: With the increasing incidence of obesity and the childbearing-age delay among women, a debate over obesity's impacts on pregnancy and neonatal outcomes becomes hot. The potential negative effects of obesity and aging on fertilit…

In this multicenter, non-inferiority, randomized trial, we randomly assigned 992 women undergoing in-vitro fertilization (IVF) with a good prognosis (aged 20-40, ≥3 transferrable cleavage-stage embryos) to strategies of blastocyst-stage (n …

BACKGROUND: Ensuring women's sexual and reproductive health (SRH) is a fundamental human right and key to 2030 agenda of the UN Sustainable Development Goals (SDGs), yet limited evidence exists on SRH in China, including national estimates …

OBJECTIVE: To investigate the effects of combining gonadotropin-releasing hormone agonist (GnRHa) downregulation with hormone replacement therapy (HRT, GnRHa-HRT) on the clinical outcomes of patients undergoing frozen-thawed embryo transfer…

OBJECTIVE: To utilize vast genetic data to reveal the interplay between 41 systemic inflammatory factors and endometriosis. DESIGN: Bidirectional Mendelian randomization study. MAINS OUTCOME MEASURES: This study obtained believable geneti…

BACKGROUND: Insulin resistance (IR) may adversely impact the in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) outcomes. However, the association of IR with ovarian sensitivity during controlled ovarian hyperstimulatio…

OBJECTIVE: The objective of the study was to explore the effect of body mass index (BMI) and insulin resistance (IR) levels on first-time assisted conception results and perinatal outcomes in young polycystic ovary syndrome (PCOS) patients.…

INTRODUCTION: Hormone replacement treatment (HRT) is the most commonly used endometrial preparation protocol for frozen embryo transfer (FET) in patients with polycystic ovary syndrome (PCOS). However, studies have found that HRT may increa…

(1) Background: A cesarean scar defect may cause localized inflammation of the endometrial tissue, and various researchers believe that the presence of a cesarean scar defect is associated with chronic endometritis. However, there is no rep…

In vitro fertilization and embryo transfer (IVF-ET) is one of the effective methods to treat female infertility. Poor endometrial receptivity (ER) is an important factor leading to embryo implantation dysfunction, which can reduce pregnancy…

BACKGROUND: The effect of premature progesterone elevation on assisted reproductive technology has been debated. In different ovarian stimulation protocols, ovarian responses, and embryos transferred, conflicting results reside regarding th…

BACKGROUND: Infertility is a reproductive health problem which affects not only individuals, families and social populations. Recently, the infertility rate in China has a trend of increase year by year, and few studies have reported the in…

PURPOSE: This review aims to summarize the key findings of several miRNAs and their roles in polycystic ovary syndrome with insulin resistance, characterize the disease pathogenesis, and establish a new theoretical basis for diagnosing, tre…

BACKGROUND: Poor ovarian response (POR), a manifestation of low ovarian reserve and ovarian aging, leads to a significant reduction in the pregnancy rate after in vitro fertilization-embryo transfer. Acupuncture has increasingly been used t…

In this retrospective study, we investigate the relationship between embryo arrest and polycystic ovary syndrome (PCOS) during in vitro fertilization-embryo transfer (IVF-ET). In this study, 667 subjects were enrolled, including 330 patient…
