Prostaglandin F2-alpha production in men
As I know:

One of the most important chemical mediators are prostaglandins that in vivo act on different cell receptors and have different effects on the body. Prostaglandins are twenty-carbon lipid molecules and structurally similar to cholesterol. Prostaglandins have different types, such as F2, E2 alpha, PGI2, and so on.

A phospholipase enzyme converts phospholipids of cell membranes into arachidonic acid. The arachidonic acid within the cyclooxygenase enzyme or Cox (both type 1 and 2) can be converted to prostaglandins.

PGF2alpha has functions in uterus contraction and bronchoconstriction, so I think both uterus and lung cells produce it.

I have no special information about production of PGF2alpha in men.
