Association between decreased ovarian reserve and poor oocyte quality.

Objective: To analyze the association between oocyte quality and decreased ovarian reserve (DOR) markers in young women undergoing controlled ovarian stimulation (COS).

Methods: This retrospective study included 49 patients classified as having DOR based on anti-Müllerian hormone (AMH) levels, follicle-stimulating hormone (FSH) levels, or antral follicle counts (AFCs; <10). Images of all obtained oocytes were analyzed, and oocyte quality was classified according to maturity and morphology.
