The rhesus monkey has fewer corpuscular receptors in the prepuce (foreskin) and more corpuscular receptors in the glans (head). In humans, however, the [[glans penis]] has few corpuscular receptors and predominant free nerve endings,<ref>{{REFjournal

Protopathic simply refers to a low order of sensibility (consciousness of sensation), such as to deep pressure and pain, that is poorly localised. The human glans penis has virtually no fine touch sensation and can only sense deep pressure and pain at a high threshold.<ref>Von, F.M. (1894). Beiträge zur Physiologie des Schmerzsinns.
