Preputial gland
Exocrine gland in the penis or clitoris / From Wikipedia, the free encyclopedia
Preputial glands are exocrine glands in the prepuce in front of the penis. They occur in many mammals, including canids,[1] mice,[2] ferrets,[3] rhinoceroses,[4] and even-toed ungulates[5] and produce pheromones. The preputial glands of female animals are sometimes called clitoral glands.
Male canids scent-mark their territories with urine and preputial gland secretions.[1][6] The preputial glands of male musk deer produce strong-smelling deer musk which is of economic importance, as it is used in perfumes.[7]
