BACKGROUND AND OBJECTIVE: Ovarian endometriosis (OE), characterized by endometriotic cysts, adversely affects ovarian function and comprises in vitro fertilization and embryo transfer (IVF-ET) outcomes. Acupoint application therapy (AAT), w…

IntroductionOptimal 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 reduce…

BackgroundTo 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.MethodsTh…

BackgroundSeveral 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 strategy…

BackgroundThe 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 this…

ObjectiveTo evaluate whether dual trigger could improve reproductive outcomes in women with low oocyte maturation rates compare to human chorionic gonadotropin (hCG) trigger.MethodsThis study included expected normal ovarian responders youn…

BackgroundExposure 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 o…

Study questionIn 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?S…

IntroductionAdvanced 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 (IV…

BackgroundAge-related diminished ovarian reserve (DOR) is not absolute. Some advanced maternal age (AMA) still have normal ovarian reserve (NOR) and often show better pregnancy outcomes. Exploring the transcriptomic profile of granulosa cel…

IntroductionThe 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 of…

ObjectiveThe purpose of this study is to determine whether intracytoplasmic sperm injection (ICSI) is beneficial in patients with non-male factor infertility.MethodsThis systematic review and meta-analysis included articles from inception t…

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 questionWhat 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?DesignIn a retrospective …

BackgroundThe optimal time at which to perform a frozen-thawed embryo transfer (FET) following a failed in-vitro fertilization-embryo transfer (IVF-ET) attempt remains elusive to most reproductive experts. Physicians often delay the introdu…

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)…

ObjectiveThe 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 vitr…

BackgroundBorderline form of empty follicle syndrome is a condition in which only a few mature or immature oocytes are recovered after meticulous follicular aspiration, despite adequate ovarian response to stimulation. It is a rare phenomen…

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…

Objective: To investigate the effect of the duration of gonadotropin releasing hormone agonist (GnRH-a) use on the outcome of in vitro fertilization and embryo transfer (IVF-ET) during the short-acting long-term hyperstimulation cycle. Meth…

PurposeOur research aimed to evaluate the effect of endometriosis on folliculogenesis and pregnancy, and to assess the involvement of inflammatory factors (IL1b, PGE2, PGF2α, and TGFβ2) in follicular fluid.MethodsA total of 65 follicular fl…
