The glans penis (or simply glans) is the sensitive tip of the penis. In some Male Mammals the scrotum - also 'scrutum' or 'scrootum' - is a protuberance of Skin and Muscle containing the Testicles Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Arteries are Blood vessels that carry blood away from the Heart. The urethral artery arises a short distance in front of the Artery of the urethral bulb. Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group The penis (plural penises, penes It is also commonly referred to as the "head" of the penis. Slang terms include "helmet" and "bell end". When the penis is flaccid it is wholly or partially covered by the foreskin, except in men who have been circumcised. In Male Human Anatomy, the foreskin or prepuce (a technically broader term that also includes the Clitoral hood, the homologous Male circumcision is the removal of some or all of the Foreskin (prepuce from the Penis.

Medical considerations

The meatus (opening) of the urethra is at the tip of the glans penis. In circumcised infants who wear diapers, the meatal area of the glans penis is without the protection of the foreskin and at slight risk of meatitis, meatal ulceration, and meatal stenosis. "Nappy" redirects here For other uses see Nappy (disambiguation and Diaper (disambiguation. Urethral meatal stenosis or urethral stricture is a narrowing ( Stenosis) of the opening of the Urethra at the external meatus (pronounced [1]

The epithelium of the glans penis is mucocutaneous tissue. [2] Birley et al. report that excessive washing with soap may dry the mucous membrane that covers the glans penis and cause non-specific dermatitis. Dermatitis is a Blanket term meaning any " Inflammation of the skin" (e [3]

Inflammation of the glans penis is known as balanitis. Balanitis is Inflammation of the Glans penis (from Greek: βάλανος balanos "acorn" It occurs in 3–11% of males, and up to 35% of diabetic males. It has many causes, including irritation, or infection with a wide variety of pathogens. Careful identification of the cause with the aid of patient history, physical examination, swabs and cultures, and biopsy are essential in order to determine the proper treatment. [4]

Anatomical details

The glans penis is the expanded cap of the corpus spongiosum. The penis (plural penises, penes Corpus spongiosum (Plural Corpora Spongiosa (also known as corpus cavernosum urethrae in older texts is the mass of spongy tissue surrounding the male Urethra It is moulded on the rounded ends of the Corpora cavernosa penis, extending farther on their upper than on their lower surfaces. At the summit of the glans is the slit-like vertical external urethral orifice. The circumference of the base of the glans forms a rounded projecting border, the corona glandis, overhanging a deep retroglandular sulcus (the coronal sulcus), behind which is the neck of the penis. A sulcus (pronounced with a hard c (pl sulci) is a depression or fissure in the surface of an organ especially the Brain. The proportional size of the glans penis can vary greatly.

The foreskin maintains the mucosa in a moist environment. [5] In males who have been circumcised, but have not undergone restoration, the glans is permanently exposed and dry. Male circumcision is the removal of some or all of the Foreskin (prepuce from the Penis. Foreskin restoration is the process of expanding the residual Skin on the Penis, via surgical or non-surgical methods to create the appearance of a natural Szabo and Short found that the glans of the circumcised penis does not develop a thicker keratinization layer. [6] Studies have suggested that the glans is equally sensitive in circumcised and uncircumcised males. [7] [8]

Halata & Munger (1986) report that the density of genital corpuscles is greatest in the corona glandis,[9] while Yang & Bradley (1998) report that their study "showed no areas in the glans to be more densely innervated than others. End-bulbs found in the Penis and the Clitoris have received the name of genital corpuscles; in these situations they have a Mulberry -like appearance "[10]

Halata & Spathe (1997) reported that "the glans penis contains a predominance of free nerve endings, numerous genital end bulbs and rarely Pacinian and Ruffinian corpuscles. Merkel nerve endings and Meissner corpuscles are not present. "[2]

Yang & Bradley argue that "The distinct pattern of innervation of the glans emphasizes the role of the glans as a sensory structure". [10]
