However, the endometrial p(Y705)-STAT3 expression level was decreased by 50% in women with adenomyosis compared with that in normal controls (Figures 4(a) and 4(c), P<0.001), and the protein levels of p-STAT3 and IL-10 were positively correlated (Figure 4(d), r = 0.712, P < 0.01). This evidence concerns the gene STAT3 and adenomyosis.
