BACKGROUND: Oxidative balance within follicular fluid (FF) plays an important role in oocyte competence and female fertility. However, most previous studies have focused on isolated oxidative biomarkers rather than on the coordinated organi…

INTRODUCTION: Infertility treatment may be influenced by systemic metabolic and redox imbalances. This prospective observational (cross-sectional) study aimed to evaluate the impact of clinical risk factors on oxidative stress markers and c…

The purpose of our study was to determine the influence of lead and cadmium in concentrations commonly found in the environment on the redox system of the follicular fluid (FF) and on the results of assisted reproduction. A prospective stud…

BACKGROUND: Oxidative stress appears to be involved in oocyte growth and maturation that when impaired results in poor embryo quality and lower potential to implant. The biochemical microenvironment of the oocyte (follicular fluid (FF)) con…

BACKGROUND: Anti-Müllerian hormone (AMH) is considered to be one of the most significant indicators of women's fertility. Many studies have shown that vitamin D may modify human reproductive functions; however, the results are conflicting. …
