Penis ventral surface

Plate 6.127 Genital Corpuscle

Human, 10% formalin, H. & E., 213 x.

Beneath the thin stratified squamous keratinized epithelium, in the dense irregular connective tissue of the dermis, genital corpuscles may be found. These tactile-type sensory receptors are similar in appearance to Meissner's corpuscles (see Plates 123 and 138) except that they are not found in dermal papillae. They are found most frequently in the dermis on the ventral side of the penis.

Stimulation of these receptors leads to erection and ejaculation of semen.

Note that the cells of the deep layer of the skin contain melanin pigment granules.
