ANGPT1 and adenomyosis: We compared vascular endothelial growth factor (VEGF), angiopoietin-1 (ANGPT-1), and angiopoietin-2 (ANGPT-2) expression in eutopic and ectopic endometria from patients with adenomyosis and evaluated whether the levonorgestrel intrauterine system (LNG-IUS) modulates these angiogenic markers.
