Suspensory Ligament Of The Penis
The suspensory ligament of the penis is a triangular midline structure anchoring the penis to the pubic symphysis, holding the penis close to the pubic bone and supporting it during erection. The ligament does not directly connect to the corpus cavernosum penis, but may still play a role in erectile dysfunction. The ligament can be surgically lengthened in a procedure known as ligamentolysis, which is a form of penis enlargement. Anatomy Structure The ligament is composed of a midline lamina, and two lateral laminae. Some of the fibres of the ligament come to constitute the fundiform ligament of the penis, extending into the scrotal septum. Attachments The ligament attaches by its apex onto the symphysis pubis and linea alba, and by its base onto the dorsal and lateral aspects of the corpora cavernosa penis. The midline lamina splits inferiorly/distally to attach onto each corpus cavernosus penis lateral to the groove of the deep dorsal vein of penis, whereas each ...

Pubic Symphysis
The pubic symphysis (: symphyses) is a secondary cartilaginous joint between the left and right superior rami of the pubis of the hip bones. It is in front of and below the urinary bladder. In males, the suspensory ligament of the penis attaches to the pubic symphysis. In females, the pubic symphysis is attached to the suspensory ligament of the clitoris. In most adults, it can be moved roughly 2 mm and with 1 degree rotation. This increases for women at the time of childbirth. The name comes from the Greek word ''symphysis'', meaning 'growing together'. Structure The pubic symphysis is a nonsynovial amphiarthrodial joint. The width of the pubic symphysis at the front is 3–5 mm greater than its width at the back. This joint is connected by fibrocartilage and may contain a fluid-filled cavity; the center is avascular, possibly due to the nature of the compressive forces passing through this joint, which may lead to harmful vascular disease. The ends of both pubi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Penis
A penis (; : penises or penes) is a sex organ through which male and hermaphrodite animals expel semen during copulation (zoology), copulation, and through which male placental mammals and marsupials also Urination, urinate. The term ''penis'' applies to many intromittent organs of vertebrates and invertebrates, but not to all. As an example, the intromittent organ of most Cephalopoda is the hectocotylus, a specialized arm, and male spiders use their pedipalps. Even within the Vertebrata, there are morphological variants with specific terminology, such as Hemipenis, hemipenes. Etymology The word "penis" is taken from the Latin word for "Latin profanity#Synonyms and metaphors, tail". Some derive that from Proto-Indo-European language, Indo-European ''*pesnis'', and the Greek word πέος = "penis" from Indo-European ''*pesos''. Prior to the adoption of the Latin word in English, the penis was referred to as a "yard". The Oxford English Dictionary cites an example of the w ...

Erection
An erection (clinically: penile erection or penile tumescence) is a Physiology, physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal, sexual attraction or libido, although erections can also be spontaneous. The shape, angle, and direction of an erection vary considerably between humans. Physiologically, an erection is required for a male to effect penetration or sexual intercourse and is triggered by the parasympathetic division of the autonomic nervous system, causing the levels of nitric oxide (a vasodilation, vasodilator) to rise in the Trabeculae of corpora cavernosa of penis, trabecular artery, arteries and smooth muscle of the penis. The arteries Vasodilation, dilate causing the Corpus cavernosum penis, corpora cavernosa of the penis (and to a lesser extent the corpus spongiosum) to fill ...

Corpus Cavernosum Penis
A corpus cavernosum penis (singular) (from Latin, characterised by "cavities/ hollows" of the penis, : corpora cavernosa) is one of a pair of sponge-like regions of erectile tissue, which contain most of the blood in the penis of several animals during an erection. It is homologous to the corpus cavernosum clitoridis in the female. Structure The corpora cavernosa are two expandable erectile tissues along the length of the penis, which fill with blood during penile erection. The two corpora cavernosa lie along the penile shaft, from the pubic bones to the head of the penis, where they join. These formations are made of a sponge-like tissue containing trabeculae, irregular blood-filled spaces lined by endothelium and separated by septum of the penis. The male anatomy has no vestibular bulbs, but instead a corpus spongiosum, a smaller region of erectile tissue along the bottom of the penis, which contains the urethra and forms the glans penis.

Erectile Dysfunction
Erectile dysfunction (ED), also referred to as impotence, is a form of sexual dysfunction in males characterized by the persistent or recurring inability to achieve or maintain a Human penis, penile erection with sufficient rigidity and duration for satisfactory sexual activity. It is the most common sexual problem in males and can cause psychological distress due to its impact on self-image and sexual relationships. The majority of ED cases are attributed to physical risk factors and predictive factors. These factors can be categorized as vascular, neurological, local penile, hormonal, and drug-induced. Notable predictors of ED include aging, cardiovascular disease, diabetes mellitus, Hypertension, high blood pressure, obesity, Dyslipidemia, abnormal lipid levels in the blood, hypogonadism, smoking, Depression (mood), depression, and Adverse drug reactions, medication use. Approximately 10% of cases are linked to psychosocial factors, encompassing conditions such as depressio ...

Penis Enlargement
Penis enlargement, or male enhancement, is any technique aimed to increase the size of a human penis. Some methods aim to increase total length, others the shaft's girth, and yet others the glans and foreskin size. Techniques include surgery, supplements, ointments, patches, and physical methods like pumping, jelqing, and traction. Surgical penis enlargement methods can be effective; however, such methods carry risks of complications and are not medically indicated except in cases involving a micropenis. Non-invasive methods have received little scientific study, and most lack scientific evidence of effectiveness. However, limited scientific evidence supports some elongation by prolonged traction. Some quack products may improve penis erection, mistaken by consumers for penis enlargement. Surgical methods There are several surgical penis enlargement treatments, most of which carry a risk of significant complications. Procedures by unlicensed surgeons can lead to serious ...

Fundiform Ligament
The fundiform ligament of the penis is a structure of the external genitalia whose descriptions differ according to the source consulted. The 41st Edition of '' Gray's Anatomy'' (2015) and ''Traité d'Anatomie humaine'' do not acknowledge this structure. Some sources equate the fundiform ligament with the Scarpa fascia. According to the ''Medical Dictionary of the French Academy of Medicine'' the fundiform ligament is a bilaterally paired bundle of fibres of the lateral lamina of the suspensory ligament of penis which curve around the lateral and inferior aspects of the penis to unite with the contralateral fundiform ligament beneath the urethral aspect of the penis; the two fundiform ligaments thus form a sling which offers structural support to the penis. Although rarely mentioned, this ligament is also found in females (at the clitoris In amniotes, the clitoris ( or ; : clitorises or clitorides) is a female sex organ. In humans, it is the vulva's most erogenous zon ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Scrotal Septum
The septum of scrotum or scrotal septum is an incomplete vertical wall (septum) that divides the scrotum into two compartments –each containing a single testis. It consists of flexible connective tissue and nonstriated muscle (dartos fascia The dartos fascia, dartos tunic or simply dartos is a layer of connective tissue found in the penile shaft, foreskin and scrotum. The penile portion is referred to as the superficial fascia of penis or the subcutaneous tissue of penis, while the ...). The site of the median septum is apparent on the surface of the scrotum along a median longitudinal ridge called the scrotal raphe. The perineal raphe further extends forward to the undersurface of the penis and backward to the anal opening. The purpose of the median septum is to compartmentalize each testis in order to prevent friction or trauma. The scrotal skin is vascularized via the two external pudental arteries and the internal pudental artery. The central territory of the scrotum ...

Linea Alba (abdomen)
The linea alba (Latin for: white line) is a strong fibrous midline structure of the anterior abdominal wall situated between the two recti abdominis muscles (one on either side). The umbilicus (navel) is present on the linea alba through which foetal umbilical vessels pass before birth. The linea alba is formed by the union of aponeuroses (of the muscles of the anterior abdominal wall) that collectively make up the rectus sheath. The linea alba attaches to the xiphoid process superiorly, and to the pubic symphysis inferiorly. It is narrow inferiorly where the two recti abdominis muscles are in contact with each other posterior to it, and broadens superior-ward from just inferior to the umbilicus. The name means ''white line'' as it is composed mostly of collagen connective tissue, which has a white appearance. In sufficiently muscular individuals, its presence can be seen on the skin, forming the depression between the left and right halves of a " six pack". Function The l ...

Deep Dorsal Vein Of Penis
In human male anatomy, the dorsal veins of the penis are blood vessels that drain the shaft ( corpora cavernosa, corpus spongiosum), the skin and the glans of the human penis. They are typically located in the midline on the dorsal aspect of the penis and they comprise the superficial dorsal vein of the penis, that lies in the subcutaneous tissue of the shaft, and the deep dorsal vein of the penis, that lies beneath the deep fascia. Superficial dorsal vein The ''superficial dorsal vein of the penis'' belongs to the superficial drainage system. It is located within the superficial dartos fascia, a continuation of the Colles' fascia, on the dorsal surface of the penis and, in contrast to the deep dorsal vein, it lies outside the deeper Buck's fascia. It is formed by smaller superficial veins that merge on the dorsolateral aspect of the penis. It drains the prepuce and the skin of the shaft, and, running backward in the subcutaneous tissue, inclines to the right or left, and ...

Dorsal Artery Of The Penis
The dorsal artery of the penis is a bilaterally paired terminal branch of the internal pudendal artery which passes upon the dorsum of the penis to the base of the glans penis, where it unites with its contralateral partner and supply the glans and foreskin. The dorsal artery of the penis provides blood supply to the skin and fascia of the penis (including the foreskin), and the erective tissues of the penis (especially the glans penis). The dorsal artery of the penis may be damaged in traumatic amputation of the penis and repairing the dorsal artery surgically prevents skin loss, but it is not essential for sexual and urinary function. Its hemodynamics and blood pressure can be assessed to test for sexual impairment. Structure The homologous artery in the female is the dorsal artery of clitoris. Origin The dorsal artery of the penis is a terminal branch of the internal pudendal artery, arising at the inferior border of the symphysis pubis. Course and relations It ...
