INTRODUCTION: Optimal luteal phase support (LPS) is essential for successful embryo transfer. In our previous study, we found that LPS combined with Gushen Antai pill (GSATP) could significantly improve ongoing pregnancy rate (OPR) and redu…

BACKGROUND: To evaluate the association between seasonal temperature variations and clinical outcomes of in vitro fertilization (IVF), aiming to provide theoretical foundations for optimizing protocol timing in reproductive medicine. METHO…

BACKGROUND: Managing infertility patients with poor ovarian response (POR) to ovarian stimulation remains unmet clinically. Besides economic burdens, patients with POR have a poor prognosis during in vitro fertilization and embryo transfer …

BACKGROUND: Several studies have compared the effects of fixed and flexible gonadotropin releasing hormone antagonist (GnRH-ant) protocols during in vitro fertilization and embryo transfer (IVF-ET). However, which GnRH-ant initiation strate…

BACKGROUND: The blastocyst-stage embryo has been considered more advantageous for increasing the cumulative live birth rate (CLBR) at fresh embryo transfer (ET) compared to the cleavage-stage embryo. However, it remains uncertain whether th…

OBJECTIVE: To evaluate whether dual trigger could improve reproductive outcomes in women with low oocyte maturation rates compare to human chorionic gonadotropin (hCG) trigger. METHODS: This study included expected normal ovarian responder…

BACKGROUND: Exposure of the female reproductive tract to either seminal plasma or fluid component of the ejaculate is beneficial to achieving successful embryo implantation and normal embryo development. But whether the "physical" component…

STUDY QUESTION: In a modified natural cycle frozen-thawed embryo transfer (mNC-FET), does the premature timing of progesterone luteal phase support (LPS) initiation 24 h following human chorionic gonadotropin (hCG) trigger impact live birth…

INTRODUCTION: Advanced age is one of the primary risk factors for infertility. Poor ovarian response (POR) to exogenous gonadotropin is a prominent characteristic of advanced-age women undergoing in vitro fertilization and embryo transfer (…

INTRODUCTION: The choice of trigger drug for the controlled ovarian hyperstimulation (COH) protocol correlates with the outcome of in vitro fertilization/intracytoplasmic sperm injection embryo transfer (IVF/ICSI-ET). The co-administration …

OBJECTIVE: The purpose of this study is to determine whether intracytoplasmic sperm injection (ICSI) is beneficial in patients with non-male factor infertility. METHODS: This systematic review and meta-analysis included articles from incep…

BACKGROUND: Endometriosis (EM) leads to a decline in fertility, which is characterized by a decrease in the number and quality of follicles, and thus has a negative impact on in vitro fertilization (IVF) outcomes. However, the mechanism of …

RESEARCH QUESTION: What influence does seven days of oestrogen administration versus fourteen days have on the reproductive outcomes of frozen-thawed embryo transfer (FET) in programmed endometrial preparation cycles? DESIGN: In a retrospe…

Objective: The aim of this study is to investigate, in ovulatory patients, whether there is a difference in reproductive outcomes following frozen-thawed embryo transfer (FET) in natural cycles (NC) compared to modified natural cycles (mNC)…

BACKGROUND: Infertility is a widespread global challenge. Currently, the most effective treatment strategy for infertility is in vitro fertilization (IVF), which is an assisted reproductive technique (ART). The use of IVF for assisted pregn…

OBJECTIVE: The primary objective of the study was to assess traditional Chinese formula DKP supplementation in terms of efficacy and safety on reproductive outcomes of expected poor ovarian responder (POR, POSEIDON Group 4) undergoing in vi…

In the past decade, the number of frozen-thawed embryo transfer (FET) has increased dramatically with the expansion of surgical indications and the improvement of freezing related technologies. How to improve the success rate and reduce the…
