Oocyte/embryo defects can result in oocyte maturation arrest, fertilization failure, embryonic arrest, and infertility as well as recurrent in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) failures. However, the genet…

BACKGROUND: Elevated maternal body mass index (BMI) increases miscarriage risk in assisted reproductive technology, but it is unclear whether this risk differs between singleton and twin pregnancies. Twin gestations impose greater metabolic…

PURPOSE: This 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 highlight…

OBJECTIVE: For patients with polycystic ovary syndrome (PCOS) to undergo in vitro fertilization (IVF) and embryo transfer (ET), there has been no consensus regarding which protocol is the most optimal for live birth rate in fresh cycles. We…

IMPORTANCE: Implantation failure remains a critical barrier to in vitro fertilization. Prednisone, as an immune-regulatory agent, is widely used to improve the probability of implantation and pregnancy, although the evidence for efficacy is…

Objective: To investigate the effect of progesterone elevation during late follicular phase on early pregnancy outcomes and live births after fresh embryo transfers. Methods: Patients who underwent IVF/ICSI treatment cycles were retrospecti…

Morroniside is the main ingredient of Cornus officinalis and has a variety of biological activities including antioxidative effects. Ovarian granulosa cells (GCs) are responsible for regulating the development and atresia of follicles, whic…

OBJECTIVE: To evaluate the pregnancy outcomes of progestin-primed ovarian stimulation (PPOS) protocol for patients with endometrioma underwent in vitro fertilization/intra-cytoplasmic sperm injection embryo transfer (IVF/ICSI-ET). DESIGN: …

OBJECTIVE: To retrospectively analyze the association of serum estradiol (E2) levels on human chorionic gonadotropin (hCG) trigger day and live birth rates (LBRs) in women undergoing fresh embryo transfer and not exhibiting polycystic ovary…

OBJECTIVE: To investigate the effect of two treatments on the outcome of freeze-thaw embryo transfer for pregnancy assistance in thin endometrium. METHODS: A retrospective study was conducted on 66 patients who failed in the first cycle tr…

BACKGROUND: With the development of embryo freezing and warming technology, frozen-thawed embryo transfer (FET) has been widely utilized. However, studies investigating the association between cryopreservation duration and FET outcomes are …

OBJECTIVE: To examine the association between body mass index (BMI) and the outcome of in vitro fertilization or intracytoplasmic sperm injection embryo transfer- (IVF/ICSI-ET) assisted reproduction in women with polycystic ovary syndrome (…

BACKGROUND: Women undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) who have a predicted poor ovarian response (POR) present a challenge for reproductive medicine specialists. Traditional Chinese medicine (TCM)…

OBJECTIVES: The purpose of this study was to investigate the change in plasma anandamide (AEA) levels throughout the normal menstrual cycle, and to analyze the relationship among AEA, sex steroids and gonadotrophins. MATERIALS AND METHODS:…

BACKGROUND/AIMS: We investigated the role of the endocannabinoid system (ECS) in the endometrium of unexplained infertility (UI) patients, and effect of anandamide (AEA) on leukemia inhibitory factor (LIF). METHODS: Patients were divided i…

Objective To investigate the levels of matrix metalloproteinase(MMP)-2,MMP-9 and their tissue inhibitors(TIMP-2 and TIMP-1) in follicular fluid of patients with polycystic ovary syndrome(PCOS) and normally ovulating women who receive in vit…
