The functional deterioration of granulosa cells (GCs), essential for follicular growth, steroidogenesis, and oocyte competence, indicates ovarian aging and reduced fertility. An expanding corpus of research indicates that oxidative stress i…

The success of in vitro fertilization (IVF) and female reproductive capacity are significantly determined by oocyte quality. Increasing data highlights the significance of oxidative stress-a state of imbalance between reactive oxygen specie…

Background: Elastography is an ultrasound-based imaging technology that allows for quantitative measurement of tissue stiffness and elasticity. In reproductive medicine, it is a potential non-invasive method for assessing ovarian activity, …

Background: Epigenetic modifications have an important role in controlling ovarian function, modulating ovarian response and implantation success in Assisted Reproductive Technologies (ART). The alterations, such as DNA methylation and non-…

Exosomal microRNAs (ex-miRs), encapsulated in extracellular vesicles (EVs), play a vital role in facilitating paracrine communication among granulosa cells (GCs), cumulus cells (CCs), and the oocyte inside follicular fluid (FF). These small…

Background/Objectives: Epithelial-Mesenchymal Transition (EMT) is the process by which epithelial cells acquire mesenchymal properties, which helps endometriotic cells migrate and invade. This study looks at the expression of E-CADHERIN, a …

Ferroptosis is a novel kind of regulated cell death that occurs when redox equilibrium is disrupted, leading to iron-dependent lipid peroxidation. Ferroptosis is defined by the buildup of deleterious lipid hydroperoxides, the inactivation o…

Numerous infants have been conceived by in vitro fertilization (IVF) and other assisted reproductive technologies (ART). Increasing evidence indicates that these approaches induce minor alterations in molecules during the initial phases of …

Background: Endometrial receptivity is crucial for successful embryo implantation in assisted reproductive technologies (ARTs). MicroRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs) have emerged as important post-…

Human infertility represents a multifaceted condition, with oxidative stress (OS) and microRNAs (miRNAs) emerging as key contributors to its pathophysiology. This comprehensive review explores the complex interplay between reactive oxygen s…

Endometriosis impairs fertility by interfering with ovarian function, embryonic development, and endometrial receptivity. Extracellular vesicles (EVs) are recognised as non-invasive biomarkers that may indicate biological processes based on…

Background/objectivesApproximately 50% of infertility cases are attributable to male factors; yet conventional semen examination can not identify the molecular abnormalities that hinder sperm functionality. Extracellular vesicles (EVs) deri…

Background: Nitric oxide (NO) is an important modulator of ovarian physiology, which contributes to angiogenesis, steroidogenesis, and redox control. The stable metabolites nitrate (NO3-) and nitrite (NO2-) may indicate real-time follicular…

BackgroundObesity is a complicated, chronic condition that has a major impact on reproductive health, leading to infertility, anovulation, and poor pregnancy outcomes. It alters the hypothalamic-pituitary-ovarian (HPO) axis, promotes insuli…

Background: MicroRNAs (miRNAs) in follicular fluid (FF) are being recognized as important regulators of ovarian function and biomarkers of reproductive success. This systematic analysis investigates FF-derived miRNAs and their relationship …

Nitric oxide (NO) predominantly regulates endometrial receptivity, angiogenesis, immunological tolerance, and trophoblast invasion throughout the implantation period. Both insufficient and excessive nitric oxide production have been linked …

Background/Objectives: Premature ovarian insufficiency (POI) is a disorder that affects women under the age of 40. It is characterized by decreased ovarian function, elevated gonadotropin levels, and decreased estradiol. SARS-CoV-2 disrupts…

Obesity reduces nitric oxide (NO) production due to endothelial nitric oxide synthase (eNOS) dysfunction, resulting in oxidative stress, mitochondrial dysfunction, and chronic inflammation. These factors have a negative impact on reproducti…

Endometriosis is a benign, estrogen-dependent gynecological condition with an uncertain exact pathogenetic mechanism. The aim of this study was to evaluate the potential differential expression of Insulin Growth Factor 1 (IGF-1) isoforms in…

OBJECTIVES: Epithelial-Mesenchymal Transition (EMT), a cellular process in which epithelial cells lose epithelial characteristics while acquire mesenchymal features, is believed to contribute to migration and invasion abilities of the endom…

Estrogens and estrogen receptors (ERs) play an important role in the pathogenesis of endometriosis. The aim of this study was to investigate the presence of gene polymorphism RsaI in the gene of the estrogen receptor ERβ in the Greek female…

Background Tumor necrosis factor-alpha (TNF-α) is a pro-inflammatory cytokine which plays an important role in the pathogenesis of many diseases. Endometriosis is one of the most common gynecological diseases. The purpose of this study was …
