Estradiol and Progesterone Levels are Related to Redox Status in the Follicular Fluid During Fertilization.

Studies have reported a possible association between the levels of oxidative stress biomarkers in follicular fluid (FF) and infertility treatment outcomes. FF analysis can provide important information about oocyte quality. This study aimed to evaluate the possible correlation between oxidative stress biomarker and intrafollicular hormone levels and clinical and laboratory parameters in women during controlled ovarian stimulation.

Vitamin D Receptor Polymorphism Is Associated With Reduced Follicle Number in Women Utilizing Assisted Reproductive Technologies.

Purpose: Calcitriol, or 1,25-hydroxycholecalciferol, is the active form of vitamin D. It binds and activates vitamin D receptor (VDR). Infertility and defective folliculogenesis have been observed in female knockout mice; however, whether polymorphisms affect human ovarian responses to controlled ovarian stimulation (COS) remains unclear.
