Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

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...
Disorders of the Male Reproductive System01:20

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra. Symptoms...
Neural Regulation01:37

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
Penis01:29

Penis

The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...
Disorders of the Autonomic Nervous System01:18

Disorders of the Autonomic Nervous System

The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.
Raynaud's disease, also known as Raynaud's phenomenon, is a...
Psychosexual Stages of Personality: Genital01:23

Psychosexual Stages of Personality: Genital

The genital stage is the final phase of Sigmund Freud's theory of psychosexual development, beginning at puberty, around age 12. During this stage, sexual energy shifts from self-focused interests to external individuals, marking the development of mature adult sexuality. Freud saw this phase as a time of sexual reawakening, with desires directed toward others outside the family. A healthy transition into this stage, according to Freud, signifies the emergence of two key aspects of adult...

Area of Science:

  • Neuroscience
  • Urology
  • Reproductive Medicine

Context:

  • Neurogenic erectile dysfunction (NED) arises from disruptions in the complex neural control of erection.
  • Autonomic, somatic, or central nervous system alterations can all lead to NED.
  • Understanding these pathways is crucial for diagnosing and managing sexual health issues.

Purpose:

  • To elucidate the physiopathological mechanisms underlying neurogenic erectile dysfunction.
  • To review the most frequent neurological conditions associated with erectile dysfunction and sexual disorders.
  • To provide a comprehensive overview of the neural basis of erectile function and dysfunction.

Summary:

  • This review examines how neurological alterations impact erectile function.
  • It details the physiopathology of autonomic, somatic, and central nervous system pathways involved in erection.
  • The focus is on common neurological conditions causing erectile dysfunction and related sexual disorders.

Impact:

  • Enhances understanding of the neural basis of erectile dysfunction.
  • Provides clinicians with insights into managing patients with neurological conditions affecting sexual health.
  • Contributes to the scientific literature on neurogenic sexual dysfunction.
