Preputial gland

Preputial glands are exocrine glands that are located in the folds of skin front of the genitals of some mammals. They occur in many species, including mice, ferrets, rhinoceroses, and even-toed ungulates and produce pheromones. The glands play a role in the urine-marking behavior of canids such as gray wolves and African wild dogs. The preputial glands of female animals are sometimes called clitoral glands.

The preputial glands of male musk deer produce strong-smelling deer musk which is of economic importance, as it is used in perfumes.
