In subsequent studies, resveratrol treatment in animal models of endometriosis decreased the number and size of endometriotic implants and showed anti‐inflammatory, anti‐angiogenic, anti‐proliferative, anti‐oxidative, and pro‐apoptotic activities12 and in just one in vitro study resveratrol treatment showed anti‐inflammatory effect through suppression of IL‐8 expression in endometriotic stromal cells.14 This evidence concerns the gene CXCL8 and endometriosis.
