The distribution, metabolism and function of creatine in the male mammalian reproductive tract: a review.
Creatine is widely distributed throughout the male reproductive system in several mammalian species, and proteins involved in its metabolism and transport have been reported in a number of cell and tissue types. Creatine is synthesized within some organs, incorporating nitrogen from amino acid metabolism. Although creatine metabolism is obligatory for the motility of sea urchin spermatozoa, this does not appear to be the case for mammals. The possible functions of creatine within the reproductive tract are discussed.
