Cold Glans Syndrome
Glans insufficiency syndrome, also known as soft glans, cold glans, or glans insufficiency, is a medical condition that affects male individuals. This condition is characterized by the persistent inability of the glans penis to achieve and maintain an Erection, erect or turgid state during sexual arousal, remaining soft and cold. This condition can have an impact on a person's sexual function, including decreased sensitivity, difficulty in Erectile dysfunction, maintaining an erection, and overall quality of life. This condition is typically diagnosed among individuals who have undergone penile implant surgery, and is often underdiagnosed in the general population due to its complexity and the lack of clear nomenclature. Pathophysiology Most commonly three distinct pathophysiologies have been hypothesized: * Failure to initiate occurs due to neurologic injury affecting motor nerves such as dorsal nerve of the penis in the Corpus spongiosum (penis), corpus spongiosum, leading to ...

Andrology
Andrology (from , ''anēr'', genitive , ''andros'' 'man' and , ''-logy, -logia'') is a name for the medicine, medical specialty that deals with male health, particularly relating to the problems of the male reproductive system and urology, urological problems that are unique to men. It is the parallel to gynecology, which deals with medical issues which are specific to female health, especially reproductive and urologic health. Process Andrology covers anomalies in the connective tissues pertaining to the genitalia, as well as changes in the volume of cells, such as in genital hypertrophy or macrogenitosomia. From reproductive and urologic viewpoints, male-specific medical and surgery, surgical procedures include vasectomy, vasovasostomy (one of the vasectomy reversal procedures), orchidopexy, circumcision, sperm/semen cryopreservation, surgical sperm retrieval, semen analysis (for fertility or post-vasectomy), sperm preparation for assisted reproductive technology (ART) as wel ...

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.

Penile Erection
An erection (clinically: penile erection or penile tumescence) is a 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 vasodilator) to rise in the trabecular arteries and smooth muscle of the penis. The arteries dilate causing the corpora cavernosa of the penis (and to a lesser extent the corpus spongiosum) to fill with blood; simultaneously the ischiocavernosus and bulbospongiosus muscles compress the veins of the corpora ca ...

Penile Artery Shunt Syndrome
Penile artery shunt syndrome (PASS) is an iatrogenic clinical phenomenon first described by Tariq Hakky, Christopher Yang, Jonathan Pavlinec, Kamal Massis, and Rafael Carrion within the Sexual Medicine Program in the Department of Urology, at the University of South Florida, and Ricardo Munarriz, of Boston University School of Medicine Department of Urology in 2013. It may be a cause of refractory erectile dysfunction in patients who have undergone penile revascularization surgery. Diagnosis Treatment Percutaneous coil embolization of the aberrant obturator artery was performed. Arterial flow rapidly improved through the left dorsal penile artery, and brisk opacification was seen through to the glans penis. Post-procedure, the patient experienced an immediate improvement in erectile function. Considerations Penile revascularization is a specialized vascular-surgical treatment option for erectile dysfunction. The 2009 International Consultation on Sexual Dysfunctions recommend ...

Venous Leak
Venous leak, also called venogenic erectile dysfunction and penile venous insufficiency, is one category of vascular-induced (vasculogenic) impotence – a cause of erectile dysfunction in males. It affects all ages, being particularly awkward in young men. Much about venous leaks has not reached a consensus among the medical community, and many aspects of the condition, particularly its treatment strategies, are controversial. The prevalence of the condition is still unknown, although some sources claim it to be a common cause of erectile dysfunction. Signs and symptoms Many men with venogenic erectile dysfunction start having trouble with their erections from a young age. Common complaints include a chronic soft erection insufficient for sexual intercourse, position-dependent erectile rigidity, difficulty achieving erections, difficulty maintaining erections without constant manual stimulation, loss of penile length and girth, and a soft glans of the penis during erection tha ...

Hard Flaccid Syndrome
Hard flaccid syndrome (HFS), also known as hard flaccid (HF), is a rare acquired dysautonomic condition characterized by a flaccid penis that remains in a firm, semi-rigid state in the absence of sexual arousal. Patients often describe their flaccid penis as firm to the touch, rubbery, shrunken, and retracted, frequently accompanied by pain, discomfort, and various other symptoms. While the condition is not fully understood, current research indicates that HFS results from excessive sympathetic nervous system activity in the smooth muscle tissue of the penis, triggered by a pathological activation of a proposed pelvic/ pudendal- hypogastric reflex. Among other causes, injuries to the erect penis, blunt trauma to the pelvis or perineum, and damage to the cauda equina are thought to induce this reflex. Although unproven, it is possible that axon sprouting in sympathetic ganglia following a peripheral nerve injury is the true explanation for HFS. The majority of patients are in their ...

Penis Cross Section
A penis (; : penises or penes) is a sex organ through which male and hermaphrodite animals expel semen during copulation, and through which male placental mammals and marsupials also 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 hemipenes. Etymology The word "penis" is taken from the Latin word for "tail". Some derive that from 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 word ''yard'' used in this sense from 1379, and notes that in his ''Physical Dictionary'' of 1684, Steven Blankaart ...
