How An Erection Works

[madman]

In this video, Jonathan from the Institute of Human Anatomy discusses the mechanism behind human erections.

• 00:00 Erectile function is crucial for reproduction, and understanding its mechanisms is essential, especially for addressing erectile dysfunction.
• 01:16 Stimulation for initiating erections can be psychological or tactile, with the most sensitive area being the glans penis, which triggers a reflexive response.
• 03:19 Erectile function primarily involves reflexive activation of the parasympathetic nervous system, which controls the smooth muscle of the penis.
• 04:03 Testosterone plays a significant role in erectile function, affecting libido and overall sexual health.
• 07:53 Nitric oxide release in erectile tissues causes vasodilation, increasing blood flow and facilitating erection.

The pudendal nerve plays a significant role in erectile function. It carries autonomic, sensory, and motor fibers to the genital region, regulating erectile and ejaculatory functions. Pudendal neuralgia can lead to sexual dysfunctions, including erectile dysfunction (ED), premature ejaculation, and persistent genital arousal disorder. Studies have shown that pudendal nerve and/or artery entrapment is a reversible cause of multiple sexual dysfunctions, and interventions such as anesthetic injections, neurolysis, and decompression have been reported as potential treatment modalities[1][2]. Additionally, there is evidence that pudendal canal decompression can improve erectile dysfunction caused by pudendal canal syndrome[3]. Therefore, the pudendal nerve is closely associated with erectile function, and its entrapment or dysfunction can lead to various sexual dysfunctions, including ED.

Indeed. Most people take for granted the functions performed in some of our body parts are enabled by nerves smaller than a human hair. Cellular and vascular functions grinding out their jobs to feed them and here we are wondering why they don't work the same after 70 years.
