Human endometrial receptivity is a critical determinant of pregnancy success; however, in vivo studies of its features and regulation are particularly challenging due to ethical restrictions. Recently, the development of human endometrial a…

Reproductive longevity is essential for female fertility and healthy aging; however, the role of stress response, especially stress granule accumulation, in ovarian aging remains elusive and interventions are lacking. Here, we identified de…

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 …

Study questionWhat are the factors influencing the occurrence of monozygotic (MZ) twins in offspring conceived by assisted reproductive technology (ART)?Summary answerParental ages, the transfer of fresh versus frozen embryos, and the grade…

BACKGROUND: During the human menstrual cycle and pregnancy, the endometrium undergoes a series of dynamic remodeling processes to adapt to physiological changes. Insufficient endometrial remodeling, characterized by inadequate endometrial p…

Study questionCan whole exome sequencing (WES) followed by trio bioinformatics analysis identify novel pathogenic genetic causes of first trimester euploid miscarriage?Summary answerWe identified genetic variants in six candidate genes that…

Objective: to evaluate effects of different ovarian stimulation protocols on in vitro fertilization(IVF) or intracytoplasmic sperm injection (ICSI) outcomes in infertile women with adenomyosis. Design: A retrospective, cohort study Setting:…

RESEARCH QUESTION: Adenomyosis is a common uterine disorder of uncertain causes. Can transcriptomic analyses of the endometrium and myometrium reveal potential mechanisms underlying adenomyosis pathogenesis? DESIGN: Transcriptomic profiles…

Immune dysregulation has long been proposed as a component of premature ovarian insufficiency (POI), but the underlying mediators and mechanisms remain largely unknown. Here we showed that patients with POI had augmented T helper 1 (TH 1) r…

ProblemFor women of reproductive age, achieving a successful pregnancy requires both the normal functioning of reproductive endocrine and the health of the reproductive tract environment. We aimed to study how these fertility factors, such …

The genetic etiology of premature ovarian insufficiency (POI) has been well established to date, however, the role of long noncoding RNAs (lncRNAs) in POI is largely unknown. In this study, we identified a down-expressed lncRNA HCP5 in gran…

Adenomyosis is a prevalent, estrogen-dependent uterine disorder wherein endometrial cells are abnormally present in the myometrium and are surrounded by hyperplastic/hypertrophic smooth muscle. Its etiology is unclear, although endometrial …

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…

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…

BackgroundMultiple pregnancies are one of the major safety concerns of in vitro fertilization (IVF) due to the increased risk of maternal and neonatal complications. Single embryo transfer is the most effective way to reduce the risk of mul…

ObjectiveTo explore the potential damaging effect of chronic pelvic inflammation on ovarian reserve.DesignCase-control study.PatientsA total of 122 women with bilateral tubal occlusion, diagnosed by hysterosalipingography (HSG) and 217 wome…

To investigate the impact of an ovarian dermoid cyst or dermoid cyst surgery on ovarian reserve in patients undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). We performed a retrospective cohort study by using th…

OBJECTIVE: To investigate the impact of previous cystectomy for ovary benign cyst on ovarian reserve and pregnancy outcome in in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) cycles. METHODS: Totally 622…

PurposeThe purpose of this study is to report two cases of monozygotic quadruplet and triplet pregnancies following single embryo transfer (ET).MethodsA 29-year-old woman and a 34-year-old woman underwent ART treatment in two affiliated Uni…

Preeclampsia (PE) is a multisystem disorder unique to Homo sapiens that is known to cause maternal and perinatal mortality and morbidity. Between 5-7% of all pregnancies are affected by PE and it is responsible for approximately 50,000 mate…

BackgroundPrimary ovarian insufficiency (POI) is characterized by marked heterogeneity, but with a significant genetic contribution. Identifying exact causative genes has been challenging, with many discoveries not replicated. It is timely …
