Figure 3

Haematoxylin and eosin (H & E) stain demonstrates subepithelial lymphocytic infiltration in the endometrium at peri-implantation period (Group 2) and after the stimulation by Cu-IUD (Group 3), but not evident in the control group (Group 1). The lymphocytic infiltration is more prominent in Group 3 than that in Group 2. Immunohistochemisty shows more obvious F4/80 (macrophage) staining (n = 10, p < 0.001) in Group 3 than that in Group 1 and Group 2, whereas the proliferating cell nuclear antigen (PCNA) staining is not different among the three groups.
