Hematoxylin and eosin staining of penile tissue from control (C) (a), green tea (GT) (b) and green tea extract (GTE) (c)-treated rats. No marked differences in the tissue organisation were observed between the three groups. Cavernous tissue has a sponge-like structure, with cavernous vascular spaces (VS) lined by endothelium (arrow) and separated by trabecula composed mainly of connective tissue (Co). Smooth muscle fibres are restricted to the endothelium periphery (SM). Note the clusters of lipid-rich cells close to vessel spaces in C animals (Li). Bar 50 μm
