BACKGROUND: The follicular fluid (FF) microenvironment plays a critical role in oocyte maturation and embryo development, reflecting local ovarian activity and systemic metabolic status. While metabolic alterations in FF have been described…

Background/Objectives: Endometriosis is a chronic gynecological condition associated with infertility, oxidative stress and altered metabolic regulation. Follicular fluid reflects the microenvironment of the developing oocyte and changes in…

Background/Objectives: Endometriosis (EM) is a chronic gynecological condition associated with infertility, oxidative stress, and altered metabolic regulation. Follicular fluid (FF) reflects the microenvironment of the developing oocyte, an…

BACKGROUND: Key performance indicators (KPIs) are widely used to evaluate embryologist performance in IVF laboratories, yet they are sensitive to patient demographics, treatment indications, and case allocation. Artificial intelligence (AI)…

Infertility rates are indeed increasing globally, which emphasizes a pressing need to identify novel biomarkers exhibiting superior potential for laboratory diagnosis and personalized clinical management. This study aimed to explore the bio…

BACKGROUND: Endometriosis is one of the most common gynecological diseases that can lead to infertility. The aim of this quantitative, descriptive, and cross-sectional study was to analyze the prevalence and the annual nationwide health ins…

The global prevalence of insulin resistance (IR) is increasing continuously, influencing metabolic parameters and fertility. The metabolic changes due to IR can alter the molecular composition of plasma and other body fluids. Follicular flu…

Infertility affects millions worldwide, posing a significant global health challenge. The proteomic analysis of follicular fluid provides a comprehensive view of the complex molecular landscape within ovarian follicles, offering valuable in…

Endometriosis is a disease that is often diagnosed late and that may lead to significant reduction in quality of life and serious complications (e.g., infertility). We aimed to assess the prevalence and the annual, nationwide health insuran…

This study aimed to evaluate the interrelationship between telomere length, telomerase activity and oxidative DNA damage in patients undergoing in vitro fertilization (IVF). This single-center, observational clinical study comprised 102 uns…

Examining possible psychosocial maladjustments should be an integral part of fertility care. For the early detection of vulnerability, the present study aimed to adapt and test the reliability and validity of the Hungarian version of SCREEN…

(1) Background: This study was designed to define whether pretreatment habitual physical activity (PA)-induced oxidative stress (OS) influences outcome measures by using 8-hydroxy-2′-deoxyguanosine (8-OHdG) in saliva samples of patients und…

The most recent studies of progesterone research provide remarkable insights into the physiological role and clinical importance of this hormone. Although the name progesterone itself means "promoting gestation", this steroid hormone is far…

BACKGROUND: National, regional and global trends in prevalence of infertility indicate its public health importance, however it effects various life dimensions of individuals and couples as well. Lifestyle habits may counteract with these f…

OBJECTIVE: This study aimed to examine the effect of interactions between serotonin (5-HT), brain-derived neurotrophic factor (BDNF), and kisspeptin on the reproductive potential in women receiving in vitro fertilization (IVF). METHODS: Pa…

OBJECTIVE: This observational, clinical study was designed to assess the role of sirtuin 1 (SIRT1), sirtuin 6 (SIRT6), and resveratrol in in vitro fertilization (IVF). METHODS: Paired serum and follicular fluid (FF) samples were obtained f…

This study was designed to evaluate the levels of oxidative stress (OS) markers, total non-enzymatic antioxidant capacity (TAC) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) in the serum and follicular fluid (FF) of patients undergoing in vitro …
