This study aimed to assess the penile length–somatometric parameters relationship in healthy Egyptian men. Two thousand physically normal men (22–40 years) were subjected to measurement of stretched penile length, glans penis, testis size, index finger, weight, height, span, body mass index (BMI), waist circumference, hip circumference and waist/hip ratio. The mean stretched penile length of the studied subjects was 13.84 ± 1.35 cm (range 12–19 cm), and the mean glans penis length was 2.6 ± 0.4 cm (range 1.7–3.8 cm). Penile length demonstrated positive significant correlation with glans penis length, index finger length, BMI and significant negative correlation with waist/hip ratio. On the other hand, penile length demonstrated nonsignificant correlation with age, weight, height, waist circumference, span or testicular size. It is concluded that the penile length-somatometric parameters relationship in healthy Egyptian men is mostly related to glans penis and index finger lengths.

The male anatomy showing the location of the glans penis

The glans penis, commonly referred to as the glans, is a structure at the distal end of the penis in male mammals. It is anatomically homologous to the clitoral glans, and like it, the glans penis is the most sensitive erogenous zone and primary anatomical source of male sexual pleasure.^[2][3] The glans penis may be smooth, spiny, elongated, or divided in other mammals.

Typically, the glans is completely or partially covered by the foreskin in humans, except in those who have been circumcised. The foreskin can generally be retracted over and past the glans, and may automatically retract during an erection. The glans is more commonly known as the "head" or the "tip" of the penis. The medical name comes from the Latin words glans ("acorn") and penis ("of the penis").

In humans[edit]

Structure[edit]

The glans penis is the expanded cap of the corpus spongiosum. 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 groove known as the coronal sulcus, behind which is the neck of the penis. The proportional size of the glans penis can vary greatly. On some penises it is much wider in circumference than the shaft, giving the penis a mushroom-like appearance, and on others it is narrower and more akin to a probe in shape.^{[citation needed]} The soft cushiony texture of the glans absorbs impact during rigorous instances of copulation.^[4]

The foreskin maintains the mucosa in a moist environment.^[5] Circumcised penises have a glans which is permanently exposed and dry. Several studies have suggested the glans is equally sensitive in both circumcised and uncircumcised penises,^[6][7][8] while others have reported it is more sensitive in people who are not circumcised.^[9][10]

Halata & Munger (1986) report that the density of genital corpuscles is greatest in the corona glandis,^[11] while Yang & Bradley's (1998) report "showed no areas in the glans to be more densely innervated than others."^[3]

Halata & Spathe (1997) reported; "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's corpuscles are not present."^[12]

Yang & Bradley argue; "the distinct pattern of innervation of the glans emphasizes the role of the glans as a sensory structure".^[3] Some researchers have suggested that the glans has evolved to become acorn, mushroom or cone shaped so that during copulation it acts to remove any semen still there from previous sex partners, but this is not supported when looking at primate relatives who have different mating behaviors.^[13][14]

Clinical significance[edit]

The meatus (opening) of the urethra is located at the tip of the glans penis.

The epithelium of the glans penis is mucocutaneous tissue. Birley et al. report that excessive washing with soap may dry the mucous membrane which covers the glans penis and cause non-specific dermatitis.^{[citation needed]}

Inflammation of the glans penis is known as balanitis, and, occurs in 3–11% of males (up to 35% of diabetic males). Edwards reported that it is generally more common in males who have poor hygiene habits or have not been circumcised. 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.^{[citation needed]}

Meatal stenosis is a late complication of circumcision, which occurs in about 2 to 20 percent of circumcised boys.^[15][16]

Other animals[edit]

Male felids are able to urinate backwards by curving the tip of the glans penis backward.^[17][18] In cats, the glans penis is covered with spines, but in dogs, the glans is smooth. Penile spines also occur on the glans of male and female spotted hyenas.^[17]

In male dogs, the glans penis consists of two parts called the bulbus glandis and pars longa glandis.^[19] The glans of a fossa's penis extends about halfway down the shaft and is spiny except at the tip. In comparison, the glans of felids is short and spiny, while that of viverrids is smooth and long.^[20] The shape of the glans varies among different marsupial species.^[21][22][23] In most marsupials, the glans is divided, but male macropods have an undivided glans penis.^[24] The glans penis is also divided into two parts in platypuses and echidnas.^[25][26]

The glans penis of the marsh rice rat is long and robust,^[27] averaging 7.3 mm (0.29 in) long and 4.6 mm (0.18 in) broad.^[28]

In Thomasomys ucucha the glans penis is rounded, short, and small and is superficially divided into left and right halves by a trough at the top and a ridge at the bottom. Most of the glans is covered with spines, except for an area near the tip.^[29]

Winkelmann's mouse can most readily be distinguished from its close relatives by its partially corrugated glans penis.^[30]

When erect, the glans of a horse's penis increases by 3 to 4 times. The urethra opens within the urethral fossa, a small pouch at the distal end of the glans.^[31] Unlike the human glans, the glans of a horse's penis extends backwards on its shaft.^{[32][33][34][35][36][37][38][39][40]}

Males of Racey's pipistrelle bat have a narrow, egg-shaped glans penis.^[41]

The glans penis of a male cape ground squirrel is large with a prominent baculum.^[42]
