[[Alfonso Cepeda-Emiliani|Cepeda-Emiliani]] et al. (2025) reported on the sensory corpuscles found in the glans and frenular region:
<blockquote>
A wide variety of sensory corpuscles in the glans and frenular region
were spatially segregated in a highly organized manner (Figures 8–10
and Figure S4). These included genital, Krause, Pacinian, Paciniform,
Golgi-Mazzoni, Ruffini-like, Meissner, and numerous other corpuscles that were difficult to classify.<ref>{{REFjournal

When the glans penis loses the protection of the [[foreskin]] it collects a layer of [[keratin]] and loses its glossy appearance. The thick layer of keratin drastically reduces sensitivity.
<!--The human glans penis has virtually no fine touch sensation and can only sense deep pressure and pain at a high threshold. This was first reported by the inventor of the aesthesiometer <ref>{{Von (1894)}} | [[Template:Von (1894)|see more]]</p></ref>  and led Sir Henry Head to make his famous comparison with the back of the heel.<!-- <ref>{{Head (1920)}} | [[Template:Head (1920)|see more]]</p></ref> -->
