LPA; Lysophosphatidic acid, a; Significant differences with non-vitrified ovaries before culture (P<0.05), b; Significant differences with non-vitrified LPA- ovaries (P<0.05), and c; Significant differences with vitrified LPA- ovaries (P<0.05). The percentage was calculated based on the normal follicles.
