The ultrastructural characteristics of the uterine mucosa have been evaluated in menopause and postmenopause by using integrated data of transmission and scanning electron microscopy. Although the surface epithelium is always present, a continuous process of flattening, deciliation as well as a reduction in microvilli number and density is evident as age proceeds. An outstanding and original finding is the formation of complex lamellar structures, the microplicae, on the apical surface of uterine epithelial cells. These may represent a sort of "vaginalization" not only increasing surface area but acting as a protective cushion against eventual injuries due to decreasing estrogen levels. These data may complement ordinary gynecologic procedures when evaluating reproductive function in aging women.

Abstract
The ultrastructural characteristics of the uterine mucosa have been evaluated in menopause and postmenopause by using integrated data of transmission and scanning electron microscopy. Although the surface epithelium is always present, a continuous process of flattening, deciliation as well as a reduction in microvilli number and density is evident as age proceeds. An outstanding and original finding is the formation of complex lamellar structures, the microplicae, on the apical surface of uterine epithelial cells. These may represent a sort of "vaginalization" not only increasing surface area but acting as a protective cushion against eventual injuries due to decreasing estrogen levels. These data may complement ordinary gynecologic procedures when evaluating reproductive function in aging women.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
