    The study identified two distinct oxidative phenotypes in human follicular fluid related to oocyte competence and female fertility.

  • 2

    Phenotype 1 is associated with primary antioxidant defense, while Phenotype 2 involves secondary detoxification pathways.

  • 3

    Increasing BMI and idiopathic infertility were linked to decreased activity in Phenotype 1 and increased activity in Phenotype 2.

  • 4

    The findings suggest that BMI and idiopathic infertility reorganize oxidative pathways in follicular fluid through opposing effects.

  • 5

    The research challenges the single-biomarker approach in reproductive oxidative stress studies by highlighting system-level interactions.
