The ultrastructure of the human bulbo-urethral gland. 1982

L Hellgren, and E Mylius, and J Vincent

The first ultrastructural description of the human bulbo-urethral gland (Cowper's gland) is presented. In light microscopy the secretory cells are cuboidal or cylindrical with a clear cytoplasm and a peripherally located round, rather dense nucleus. Myoepithelial cells are demonstrated in the secretory tissue. The electron microscopy reveals numerous membrane bound secretory granules with dense cored matrix in the cytoplasm. This special composition of the secretory granules corresponds to the analogue glands in ram and bull. The secretory activities seem to be correlated to the development of the gland as a function of sexual maturity of the individual. Secretory granules are found also in surrounding capillaries, which suggests that this gland also has an endocrine function.

UI MeSH Term Description Entries
D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
