Erectile dysfunction

Examples of Erectile dysfunction in the following topics:

• Erectile Dysfunction and the Blue Pill

  • Erectile dysfunction (ED) is the inability to develop or maintain an erection during sexual intercourse.
  • Erectile dysfunction (ED) is sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual performance.
  • Erectile dysfunction is indicated when an erection is difficult to produce.
  • The number of hours on a bike and/or the pressure on the penis from the saddle of an upright bicycle is directly related to erectile dysfunction A recent study suggests an epidemiological association between chronic periodontitis (periodontal inflammation) and erectile dysfunction, similar to the association between periodontitis and coronary heart diseases, as well as cerebrovascular diseases.
  • In all the three conditions (erectile dysfunction, coronary heart disease, and cerebrovascular diseases), despite the epidemiological association with periodontitis, no causative connection has yet been proven.

• Prostate Disorders

  • Prostate cancer may cause pain, difficulty in urinating, problems during sexual intercourse, or erectile dysfunction.

• The Fight-or-Flight Response

  • The stress response halts or slows down various processes such as sexual responses and digestive systems to focus on the stressor situation; and typically causes negative effects like constipation, anorexia, erectile dysfunction, difficulty urinating, and difficulty maintaining sexual arousal.

• Urethra

  • The urethra consists of three coats of tissues: muscular, erectile, and mucous; the muscular layer being a continuation of the smooth muscle of the bladder. 
  • The erectile urethral tissue is specialized tissue that may become engorged with blood during sexual arousal.

• Penis

  • Unlike many other species, the human penis has no baculum, or erectile bone.
  • This allows more blood to fill the three spongy erectile tissue chambers in the penis causing it to lengthen and stiffen.
  • The engorged erectile tissue presses against and constricts the veins that carry blood away from the penis.
  • More blood enters than leaves the penis until an equilibrium is reached where an equal volume of blood flows into the dilated arteries and out of the constricted veins; a constant erectile size is achieved at this equilibrium.

• Ataxia

  • Ataxia refers to potentially debilitating motor dysfunction, which can be caused by both hereditary and environmental factors.
  • Ataxia is a nonspecific clinical manifestation implying dysfunction of the parts of the nervous system that coordinate movement, such as the cerebellum.
  • Several possible causes exist for these patterns of neurological dysfunction.
  • Cerebellar ataxia is ataxia that is due to dysfunction of the cerebellum .
  • This is generally caused by dysfunction of the dorsal columns of the spinal cord, because they carry proprioceptive information up to the brain.

• Arthroplasty

  • Arthroplasty is an operative procedure in which the arthritic or dysfunctional joint surface is replaced or repaired.
  • Arthroplasty (literally "surgical repair of joint") is an operative procedure of orthopedic surgery performed, in which the arthritic or dysfunctional joint surface is replaced with something better or by remodeling or realigning the joint by osteotomy or some other procedure .

• Disorders of the Basal Ganglia

  • Basal ganglia disease refers to physical dysfunctions that occur when basal ganglia fail to suppress unwanted movements.
  • Basal ganglia disease refers to a group of physical dysfunctions that occur when the group of nuclei in the brain, known as the basal ganglia, fail to properly suppress unwanted movements or to properly prime upper motor neuron circuits to initiate motor function.
  • Other motor deficits and common non-motor features of Parkinson's, such as autonomic dysfunction, cognitive impairment, and gait/balance difficulties, are thought to result from widespread progressive pathological changes commencing in the lower brain stem and ascending to the midbrain, amygdala, thalamus, and ultimately the cerebral cortex.
  • Recent models in mice show that the dysfunction in the cerebellum may play an equal part in dystonia.
  • Since the realization that syndromes such as Tourette syndrome and OCD are caused by dysfunction of the non-motor loops of basal ganglia circuits, new treatments for these disorders, based on treatments originally designed to treat movement disorders are being developed.

• Testes

  • They also support libido, spermatogenesis, and erectile function.

• Autoimmune Diseases

  • Despite their clinical diversity, they have one similarity, namely the dysfunction of the immune system.
  • In contrast to classical inherited genetic diseases, like sickle cell anemia, autoimmune diseases are not caused by the defect of a single gene, but by the dysfunction of the complex interaction of a group of genes.
