The microenvironment within the female reproductive tract exerts a significant influence on reproductive processes and offspring development. Oxidative stress and antioxidant defense mechanisms play an important role in this context. Dr. Juan Carlos Gutiérrez's research focuses on investigating how nutrition modulates this microenvironment and its subsequent effects on oocytes and early embryos. A primary focus is on the transfer and metabolism of bioactive dietary components in ovarian follicles, as well as the influence of polyphenols on oocyte maturation, oocyte quality, and early embryonic development. In this context, he also investigates the metabolism and gene expression of oocytes and embryos under both physiological and stress conditions. For his research, Dr. Gutiérrez primarily utilizes bovine material from slaughterhouses as well as oocytes obtained via ovum pickup. His research contributes to a more nuanced understanding of the influence of diet and individual nutrients on reproductive physiological processes.
