Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

22.2K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

3.7K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Hypertension II: Pathophysiology

1.1K
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

3.3K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

1.4K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Area of Science:

  • Male Sexual Dysfunction
  • Reproductive Medicine
  • Urology

Background:

  • Delayed ejaculation (DE) and anejaculation (AE) are uncommon male sexual dysfunctions.
  • These conditions cause significant distress to patients and partners, impacting fertility.
  • The pathophysiology remains incompletely understood, with multifactorial causes.

Purpose of the Study:

  • To review the pathophysiology of DE and AE.
  • To explore current diagnostic approaches.
  • To present available treatment options.

Main Methods:

  • Comprehensive literature search of electronic databases (PubMed, Embase) from 1966 to October 2017.
  • Combined MeSH terms/keywords related to DE/AE with epidemiological, etiological, diagnostic, and treatment concepts.
  • Reviewed relevant sexual medicine textbooks.

Main Results:

  • DE/AE pathophysiology is multifactorial, involving organic and psychosocial elements, though exact pathogenesis is unknown.
  • No gold standard exists for DE/AE diagnosis; clinical history is crucial.
  • Treatment is cause-specific, with psychological interventions, pharmacotherapy (no approved drugs), and fertility treatments available.

Conclusions:

  • DE/AE are complex conditions requiring individualized, cause-specific treatment.
  • Further research is needed to elucidate pathogenesis and establish diagnostic standards.
  • A range of interventions exist for infertile men experiencing DE/AE.
