Ejaculation involves complex physiological reflexes. Premature ejaculation, often considered psychogenic, may also stem from prostatic issues, impacting ejaculatory control and sexual health.

Area of Science:

  • Urology
  • Neuroscience
  • Sexology

Background:

  • Ejaculation is a complex physiological process involving sympathetic and sacral spinal reflexes.
  • Premature ejaculation is the most common ejaculatory disorder, with debated etiology and treatment.
  • Traditional views often attribute premature ejaculation to psychogenic factors.

Purpose of the Study:

  • To elucidate the physiological mechanisms of ejaculation.
  • To explore the etiology and pathogenesis of premature ejaculation.
  • To discuss diagnostic procedures and therapeutic options for ejaculatory disorders.

Main Methods:

  • Review of physiological mechanisms of ejaculation.
  • Analysis of current understanding of premature ejaculation's causes.

Related Experiment Videos

  • Examination of diagnostic and therapeutic advancements.

    • Main Results:

    • Ejaculation involves emission, bladder neck closure, and forceful expulsion, mediated by distinct neural pathways.
    • Prostatic inflammation/infection is frequently observed in premature ejaculation, suggesting a potential organic basis.
    • Rarer disorders include emission/ejaculation failure and urine contamination of semen.

    Conclusions:

    • Understanding ejaculation physiology is crucial for diagnosing and treating related disorders.
    • Prostatic pathologies may play a significant role in some cases of premature ejaculation.
    • Advancements in diagnostics and pharmacology are enhancing the medical sexology approach to ejaculatory dysfunction.
