Flashcards: Penis

Pre-ejaculate (also known as pre-ejaculatory fluid, pre-seminal fluid, or Cowper's fluid, and colloquially as pre-cum) is the clear, colorless, viscous fluid that is emitted from the urethra of the penis during sexual arousal.

The ejaculatory ducts (ductus ejaculatorii) are paired structures in male anatomy.

Hōnen Matsuri (豊年祭?, "Harvest Festival") is a fertility festival celebrated every year on March 15 in Japan.

Micropenis is an unusually small penis.

Ejaculation is the discharge of semen (normally containing sperm) from the male reproductory tract, usually accompanied by orgasm.

In male human anatomy, the glans penis (or simply glans, /ɡlænz/) is the sensitive bulbous structure at the distal end of the penis.

Hypospadias /haɪpoʊˈspeɪdɪəs/ is a birth defect of the urethra where the urinary opening is not at the usual location on the head of the penis.

Phimosis is a condition of the penis where the foreskin cannot be fully retracted over the glans penis.

Premature ejaculation (PE) occurs when a man experiences orgasm and expels semen soon after sexual activity and with minimal penile stimulation.

The Prince Albert (PA) is one of the more common male genital piercings.

A corpus cavernosum penis (singular) (cavernous body of the penis) is one of a pair of sponge-like regions of erectile tissue, the corpora cavernosa (plural) (cavernous bodies), which contain most of the blood in the penis during an erection.

A dildo is a sex toy, often explicitly phallic in appearance, intended for sexual penetration or other sexual activity during masturbation or with sex partners.

An erection (clinically: penile erection or penile tumescence) is a physiological phenomenon in which the penis becomes firmer, engorged and enlarged.

In male human anatomy, the foreskin is a double-layered fold of smooth muscle tissue, blood vessels, neurons, skin, and mucous membrane that covers and protects the glans penis and the urinary meatus.

Hirsuties coronae glandis (also known as "hirsutoid papillomas" and "pearly penile papules") are small protuberances that may form on the ridge of the glans of the human penis.

("Penis length" redirects here. For differences in penis length among non-human species, see Penis § In different animals.) The most accurate measurement of human penis size can be derived from several readings at different times since there is natural minor variability in size depending upon arousal level, time of day, room temperature, frequency of sexual activity, and reliability of measurement.

The Shinto Kanamara Matsuri (かなまら祭り?, "Festival of the Steel Phallus") is held each spring at the Kanayama Shrine (金山神社 Kanayama-jinja) in Kawasaki, Japan.

In anatomy, the urethra (from Greek οὐρήθρα – ourḗthrā) is a tube that connects the urinary bladder to the urinary meatus for the removal of fluids from the body.

Paraphimosis (/ˌpærəfaɪˈmoʊsᵻs/ or /ˌpærəfəˈmoʊsᵻs/) is an uncommon medical condition in which the foreskin of an uncircumcised penis becomes trapped behind the glans penis, and cannot be reduced (pulled back to its normal flaccid position covering the glans).

Priapism is a medical condition in which the erect penis does not return to its flaccid state, despite the absence of both physical and psychological stimulation, within four hours.

The human penis is an external male intromittent organ that additionally serves as the urinal duct.

The bulbus glandis (also called a knot) is an erectile tissue structure on the penis of canid mammals.

For their anterior three-fourths the corpora cavernosa penis lie in intimate apposition with one another, but behind they diverge in the form of two tapering processes, known as the crura, which are firmly connected to the ischial rami.

The corona of glans penis refers to the circumference of the base of the glans penis in human males which forms a rounded projecting border, overhanging a deep retroglandular sulcus, behind which is the neck of the penis.

In ancient civilizations, the removal of the human penis was sometimes used to demonstrate superiority or dominance over an enemy.

The body of the penis extends from the root to the ends of the corpora cavernosa penis, and in it these corpora cavernosa are intimately bound to one another.

Frenulectomy of the penis is a surgical procedure for cutting and removal of the frenulum of prepuce of penis, to correct a condition known as frenulum breve.

Just before each crus of the penis meets its fellow it presents a slight enlargement, which Georg Ludwig Kobelt named the bulb of the corpus spongiosum penis.

The cavernous portion of the urethra is narrow, and of uniform size in the body of the penis, measuring about 6 mm in diameter; it is dilated behind, within the bulb, and again anteriorly within the glans penis, where it forms the fossa navicularis urethrae.

The dorsal nerve of the penis is the deepest division of the pudendal nerve; it accompanies the internal pudendal artery along the ramus of the ischium; it then runs forward along the margin of the inferior ramus of the pubis, between the superior and inferior layers of the fascia of the urogenital diaphragm.

The corpora cavernosa penis are surrounded by a strong fibrous envelope consisting of superficial and deep fibers.

In males, the suspensory ligament of the penis is attached to the pubic symphysis, which holds the penis close to the pubic bone and supports it when erect.

Penile agenesis is a birth defect in humans, occurring about once in 5–6 million male births, in which a male child is born without a penis.

Webbed penis, also called penis palmatus or penoscrotal fusion, is an acquired or congenital condition in which the scrotal skin extends onto the ventral penile shaft.

The artery of bulb of penis (artery of the urethral bulb or bulbourethral artery) is a short artery of large caliber which arises from the internal pudendal artery between the two layers of fascia (the superior and inferior) of the urogenital diaphragm.

The deep artery of the penis (artery to the corpus cavernosum), one of the terminal branches of the internal pudendal, arises from that vessel while it is situated between the two fasciæ of the urogenital diaphragm (deep perineal pouch).

The Dorsal Artery of the Penis is a branch of the internal pudendal artery which ascends between the crus penis and the pubic symphysis, and, piercing the inferior fascia of the urogenital diaphragm, passes between the two layers of the suspensory ligament of the penis, and runs forward on the dorsum of the penis to the glans, where it divides into two branches, which supply the glans and prepuce.

The helicine arteries of penis are arteries in the penis.

Koro is a culture-specific syndrome delusional disorder in which an individual has an overpowering belief that one's genitalia are retracting and will disappear, despite the lack of any true longstanding changes to the genitals.

Male circumcision has often been, and remains, the subject of controversy on a number of grounds—including religious, ethical, sexual, and health.

In male anatomy, the lacuna magna (also called Guérin's sinus) is the largest of several recesses in the roof of the navicular fossa of the urethra.

The frenulum of prepuce of penis, often known simply as the frenulum, is an elastic band of tissue under the glans penis that connects the foreskin (prepuce) to the vernal mucosa, and helps contract the foreskin over the glans.

The corpus spongiosum is the mass of spongy tissue surrounding the male urethra within the penis.

Retrograde ejaculation occurs when semen, which would, in most cases, be ejaculated via the urethra, is redirected to the urinary bladder.

The vein of bulb of penis is a tributary of the internal pudendal vein.

Pizzle is an old English word for penis, derived from Low German pesel or Flemish Dutch pezel, diminutive of pees, meaning 'sinew'.

The brit milah (Hebrew: בְּרִית מִילָה‎‎, pronounced [bʁit miˈla]; Ashkenazi pronunciation: [bʁis ˈmilə], "covenant of circumcision"; Yiddish pronunciation: bris [bʀɪs]) is a Jewish religious male circumcision ceremony performed by a mohel ("circumciser") on the eighth day of a male infant's life.

The primary urethral groove or urethral groove is a temporary linear indentation on the underside (ventral side) of the male penis during embryonic development.

The cavernous nerves are post-ganglionic parasympathetic nerves that facilitate penile erection.

Buck's fascia (deep fascia of the penis, Gallaudet's fascia or fascia of the penis) is a layer of deep fascia covering the three erectile bodies of the penis.

In human anatomy, the dorsal veins of the penis comprise the superficial dorsal vein of the penis and the deep dorsal vein of the penis.

The tunica albuginea is the fibrous envelope of the corpora cavernosa penis.

The root of the penis is triradiate in form, consisting of the diverging crura, one on either side, and the median urethral bulb.

The subcutaneous tissue of penis (or superficial penile fascia) is continuous above with the fascia of Scarpa, and below with the dartos tunic of the scrotum and the fascia of Colles.

Chordee (/ˈkɔːrdiː/) is a condition in which the head of the penis curves downward or upward, at the junction of the head and shaft of the penis.

From the internal surface of the fibrous envelope of the corpora cavernosa penis, as well as from the sides of the septum, numerous bands or cords are given off, which cross the interior of these corpora cavernosa in all directions, subdividing them into a number of separate compartments, and giving the entire structure a spongy appearance.

The fibrous envelope of the corpus cavernosum urethrae is thinner, whiter in color, and more elastic than that of the corpora cavernosa penis.

A pseudo-penis is any structure found on an animal that, while superficially appearing to be a penis, is derived from a different developmental path.

The spongy urethra (cavernous portion of urethra, penile urethra) is the longest part of the male urethra, and is contained in the corpus spongiosum of the penis.
