BACKGROUND: Cryopreservation and warming can induce cellular stress that impairs oocyte and embryo competence, particularly in poor-prognosis patients. Although fatty acids and melatonin have been proposed to support cytoskeletal stability …

BACKGROUND: Obesity negatively affects reproduction and in vitro fertilization (IVF) outcomes. However, its effects on lipid metabolism during embryonic development remain unclear. We examined follicular fluid (FF) lipid composition and bod…

INTRODUCTION: The global adoption of the "freeze-all strategy" has led to a continuous increase in utilization of single vitrified-warmed blastocyst embryo transfer (SVBT) owing to its clinical effectiveness. Accurate prediction of clinical…

BACKGROUND: Granulosa cells play an important role in folliculogenesis, however, the role of RNA transcripts of granulosa cells in assessing embryo quality remains unclear. Therefore, we aims to investigate that RNA transcripts of granulosa…

OBJECTIVE: Dual trigger is used to induce final oocyte maturation during the process of controlled ovarian hyperstimulation, yet yielding controversial results. Also, there are yet no data regarding the effect of the dosage of the dual trig…

This study investigated the genetic association between recurrent pregnancy loss (RPL) and microRNA (miRNA) polymorphisms in miR-10aA>T, miR-30cA>G, miR-181aT>C, and miR-499bA>G in Korean women. Blood samples were collected from 381 RPL pat…

The present study aimed to investigate the potential association of five miRNA machinery gene polymorphisms (DICER1 rs3742330A>G, DROSHA rs10719T>C, RAN rs14035C>T, XPO5 rs11077A>C and DGCR8 rs417309G>A) with recurrent implantation failure …

Despite the large number of studies on blastocyst transfers, it is unclear whether day 6 blastocysts have similar pregnancy rates and safety with day 5 blastocysts. Thus, this study aimed to compare the obstetric, neonatal, and clinical out…

An Argonaute (AGO) protein within the RNA-induced silencing complex binds a microRNA, permitting the target mRNA to be silenced. We hypothesized that variations in AGO genes had the possibility including affected the miRNA function and asso…

Endometriosis is a chronic inflammatory condition that affects fertility and could be toxic to the ovary. Endometrioma per se and surgical interventions for endometrioma significantly reduce the ovarian reserve. Therefore, to prepare for su…

Recurrent implantation failure (RIF) is a common reproductive clinical condition treated by fertility specialists at in vitro fertilization (IVF) clinics. Several factors affect embryo implantation including the age of the female, the quali…

OBJECTIVE: MicroRNAs (miRNAs) regulate gene expression during the peri-implantation period. The purpose of this study was to investigate whether genetic polymorphisms in the four miRNAs associated with fetal or placental development play ro…

OBJECTIVE: Primary ovarian insufficiency (POI) is diagnosed clinically by increased follicle-stimulating hormone (FSH) levels and estradiol (E2) deficiency. A previous report suggests a possible association matrix metalloproteinase (MMP) an…

A tuboovarian abscess (TOA) during pregnancy following oocyte retrieval is extremely rare. We report a rare case of pregnancy complicated by the development of a TOA following in vitro fertilization-embryo transfer that was treated successf…
