BACKGROUND: Diminished ovarian reserve is characterized by a decrease in oocyte count and estrogen levels, which leads to infertility. The genetic and epigenetic mechanisms in MI to MII transition or complete MII phase in the oocyte maturat…

Background/Objectives: Oocyte maturation is a process involving both nuclear and cytoplasmic development regulated by epigenetic changes in gene expression. Cyclin-B3 (CCNB3) and cyclin-A2 (CCNA2) genes are thought to be involved in oocyte …

INTRODUCTION: Compaction is the first event in embryo morphogenesis. Blastocyst transfer on day five or six has been widely performed in the last decade. We investigated the clinical value of early compaction on day three for evaluation of …

Immature oocytes are retrieved and matured through in vitro maturation (IVM). Maturation, fertilization rates, and embryo development via IVM are all lower than those found in vitro fertilization (IVF) cycles. We investigated the effects of…

OBJECTIVE: To determine the effects of controlled ovarian hyperstimulation and resultant high levels of E(2) on endometrial HOXA10 expression (a marker of endometrial receptivity). DESIGN: Prospective study. SETTING: University academic m…

BACKGROUND: Interleukin (IL)-15 is a novel cytokine with immunoregulatory and angiogenic properties. We compared IL-15 levels in the peritoneal fluid (PF) of women with and without endometriosis. METHODS: PF samples were obtained from 55 w…

Interaction between endometrial stromal cells and extracellular matrix (ECM) components has a crucial role in the development of endometriosis. Endometrial stromal cells attach to the mesothelial surface of peritoneum by means of integrins …

Numerous cytokines and growth factors are synthesized in the endometrium. IL-8 is one of these cytokines regulating endometrial function. It is a neutrophil chemoattractant/ activating factor and a potent angiogenic agent. IL-8 is elevated …
