19(R)-hydroxy PGF
2α is an ω-1 hydroxylase metabolite of PGF
2α found in human semen. The concentration of 19(R)-hydroxy PGF compounds (F
2α and F
1α together) in fresh human semen is about 20 μg/ml.
1 19(R)-hydroxy PGF
2α exhibits no activity at the FP receptor of the cat iris sphincter muscle at concentrations up to 1 μM.
