Male Sexual Response: Erection & Ejaculation

30.4K
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...

Herniated Intervertebral Disc l: Introduction

13
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Spinal Nerves: Plexus II

3.0K
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Summary
This summary is machine-generated.

Men with lower lumbosacral spinal cord injuries often experience premature ejaculation (PE) following injury. This condition can manifest as rapid ejaculation or spontaneous emissions, suggesting a direct link to the lesion.

Area of Science:

  • Neuroscience
  • Urology
  • Sexology

Background:

  • Spinal cord injuries (SCIs) commonly lead to anejaculation.
  • Premature ejaculation (PE) is less frequently reported in association with lumbosacral lesions.

Purpose of the Study:

  • To investigate the occurrence and characteristics of PE in men with lumbosacral lesions.
  • To determine if PE is a consistent outcome and identify lesion types associated with PE.

Main Methods:

  • Retrospective analysis of sexological consultations for 34 men with L5-S4 lesions.
  • Assessment included psychogenic/reflexogenic erection, ejaculation, reflexes (bulbocavernosus, anal, cremasteric), and urodynamics.

Main Results:

  • 31/33 men maintained natural ejaculation, but 18 reported PE.
  • 27/34 experienced non-climactic ejaculation; 14 had dribbling ejaculation.
  • Neurological and urodynamic assessments revealed significant sensory and reflex deficits.

Conclusions:

  • Lower lumbosacral lesions frequently result in PE, often from the first ejaculation post-injury.
  • PE characteristics include rapid response to sexual thoughts or spontaneous emissions.
  • Potential mechanisms involve altered sacral inhibition or simultaneous psychogenic erection and emission pathways.
