A randomized exploratory trial in infertile patients with endometriosis (stage III–IV) within the window of implantation revealed that receiving resveratrol (400 mg) for 12–14 weeks significantly attenuated the levels of VEGF and TNF-α genes and protein in the ectopic endometrium compared with the placebo group [151]. The gene discussed is VEGFA; the disease is endometriosis.
