VEGFA and adenomyosis: The eutopic endometria of adenomyosis patients displayed significantly higher expression levels of VEGF compared with the controls (291.12 ± 35.38 vs. 150.91 ± 24.68, p < 0.01, Figure 3A vs. Figure 3E,F), whereas LNG-IUS-treated eutopic tissue showed no difference from the controls (166.43 ± 27.47 vs. 150.91 ± 24.68, p = 0.23, Figure 3C vs. Figure 3E,F).
