Fig. 7. Electrocoagulation injury increases the amount of collagen in the endometrium and reduces its thickness.

Fig. 7

Different electrical intensities were used to injure the endometrium, and tissue samples were taken at 7, 21, and 35 days post surgery. Paraffin sections were prepared and stained with Masson to detect the Collagen volume fraction (scale bar =  200 μm) (a) and HE to detect the thickness of the endometrium (scale bar = 500 μm) (b), n = 4 per group, ordinary one-way ANOVA with Dunnett’s multiple comparison test or Welch’s ANOVA test with Dunnett’s T3 multiple comparisons test. Data are presented as means ± SD. *P < 0.05, **P < 0.01, ***P < 0.001 compared with indicated groups.
