19(R)-Hydroxylated prostaglandins occur in µg/ml concentrations in the semen of some mammalian species, especially primates. In the case of humans, the compounds are primarily of the PGE series, and the hydroxyl stereochemistry is 15(S),19(R).1 19(R)-Hydroxylated prostaglandins are also found in the seminal plasma of marsupials, where F-type compounds of the 1 and 2-series predominate.2 The 15(R)-hydroxy epimer of these 19-hydroxylated prostaglandins is the inverse or "unnatural" isomer at C-15. The biological role of 19(R)-hydroxylated prostaglandins is not well established. In the F-series, 19(R)-hydroxylation is associated with a significant loss of receptor-mediated biological activity in some assays.3
