[Morphological changes in sebaceous glands with aging in human males].
Using a computer stereographic analysis, the normal human forehead skin from 16 males of ages ranging from 7 to 77 years were investigated to known the morphological changes of the sebaceous glands with aging. The volume of sebaceous glands increased abruptly in teens, reaching maximum in the 20s; it was maintained at high levels even at middle ages and then began to decrease gradually in the 60s. The volume of sebaceous glands positively correlated with the number of the sebaceous cells but not with their sizes. Ultrastructually, in the large sebaceous glands, and peripheral cells were cuboidal, whereas they were flat in the small sebaceous glands. It is concluded that the sebaceous glands in males show no morphological change in relation to age between the 20s and 50s.
