ObjectiveTo investigate the efficacies of three cycle regimens in women receiving frozen embryo transfer with a history of cesarean section: natural cycle treatment, hormone replacement therapy and treatment with gonadotropin-releasing horm…

BackgroundIt was suggested that vaccination in general might affect reproductive health. Safety of COVID-19 vaccination in women undergoing assisted reproductive techniques (ART) treatment is not well established.MethodsWe performed a retro…

ObjectiveTo examine the effects and mechanisms of transcutaneous electrical acupoint stimulation (TEAS) on pregnancy outcomes in women undergoing in vitro fertilization (IVF)-embryo transfer (ET).Design, setting, and participantsThis effica…

BackgroundAlthough oocyte quality is the dominant factor determining embryo quality, few studies have been conducted to evaluate embryo quality based on the metabolites related to the oocyte. With quantification of the follicular fluid (FF)…

Sperm morphology was once believed as one of the most predictive indicators of pregnancy outcome in assisted reproductive technology (ART). However, the impact of teratozoospermia on in vitro fertilization (IVF)/intracytoplasmic sperm injec…

BackgroundDisplacement of the window of implantation (WOI) has been proposed as an important factor contributing to repeated implantation failure (RIF). However, the use of histologic endometrial dating as a diagnostic tool of endometrial r…

Ovarian cancer is the most lethal malignancy among gynecological cancers worldwide. Most ovarian cancer patients are diagnosed at an advanced stage because of non-specific clinical symptoms. The human microbiome plays a crucial role in main…

BackgroundThe poor prognosis of patients with ovarian cancer is mainly due to cancer progression. γ-Synuclein (SNCG) has reported as a critical player in cancer metastasis. However, its biological roles and mechanism are yet incompletely un…

Objective: The POSEIDON criteria are used to stratify patients with low prognosis after assisted reproductive technology (ART) treatment. Since its introduction, there has been no large study about the prognosis of the POSEIDON population. …

BackgroundAlmost all of the previous studies related with co-administration of letrozole in IVF cycles were performed in poor responders and letrozole may reduce the total gonadotropin dose required for ovarian stimulation, and the pregnanc…

IntroductionHerlyn-Werner-Wunderlich syndrome (HWWS) is a rare congenital abnormality of the urogenital tract characterized by uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis. It is usually diagnosed after menarche, …

There are currently various protocols for in vitro fertilization (IVF). For patients with polycystic ovarian syndrome (PCOS), an optimized protocol for the downregulation of pituitary follicle stimulating hormone and luteinizing hormone via…

BackgroundAlthough Caesarean scar pregnancy (CSP) is rare, it can cause life-threatening complications. The increasing rate of Cesarean delivery plus rapid development of in vitro fertilization-embryo transfer (IVF-ET) may increase the occu…

OBJECTIVE: To investigate the outcome of in vitro fertilization and embryo transfer (IVF-ET) in special infertile patients following modified super-long down-regulation protocol combined with human menopausal gonadotropin (HMG) stimulation.…

PurposeTo compare the effectiveness of double IUI with single IUI in male factor and idiopathic infertility patients undergoing controlled ovarian hyperstimulation (COH).MethodsA prospective randomized study of 1257 COH-IUI cycles was perfo…
