An ovary of a patient from group A (<5 years after menopause). Strong cytoplasmic reaction of 17β-HSD in the surface epithelium (arrow), in the cyst epithelium (arrow) (A), in the ovarian stromal cells (arrowhead), and semi strong reaction in the vascular endothelial cells (arrow) (B). An ovary from a patient from group B (5–10 years after menopause). Strong cytoplasmicreaction of 17β-HSD in the cyst epithelium (arrow) and semi strong in ovarian stromal cells (arrowhead) (C). An ovary of a patient from group C (>10 years after menopause). Semi strong cytoplasmic expression of 17β- HSD in the vascular endothelial cells (arrow) and weak expression in the ovarian stromal cells (D). SC, stromal cells; LC, lumen cyst; LV, lumen vessel. Inserts in panels A, C and D) show negative controls. Magnification, x330.
