They are usually considered as vestigial remnants of penile spines, sensitive features found in the same location in other primates. PPPs secrete oil that moistens the glans of the penis. They do not spread and often spontaneously regress. Along with Fordyce glands PPPs secrete oils to keep the skin of the head of the penis in good condition.
