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...
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...
The Micturition Reflex01:26

The Micturition Reflex

Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
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...
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...
Sperm Transport01:15

Sperm Transport

The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
The maturation phase occurs in the epididymis, where sperm...

Summary
This summary is machine-generated.

Premature ejaculation (PE) is a common sexual dysfunction. Effective treatments exist, but PE is often underdiagnosed and undertreated due to patient and physician hesitancy.

Area of Science:

  • Urology
  • Sexology
  • Psychiatry

Context:

  • Premature ejaculation (PE) is the most prevalent male sexual disorder.
  • It significantly impacts patient morale and partner relationships.
  • PE is frequently underdiagnosed and self-diagnosed, leading to limited treatment seeking.

Purpose:

  • To review the literature and expert opinion on premature ejaculation.
  • To differentiate between lifelong and acquired PE to guide therapeutic strategies.
  • To explore etiological hypotheses, clinical types, and management options for PE.

Summary:

  • Distinguishing between lifelong and acquired PE is crucial for effective treatment.
  • Etiological factors range from psycho-sexological concepts to potential genetic and neurobiological underpinnings (e.g., serotoninergic neurotransmission).
  • Integrated therapeutic approaches, considering partner factors, may offer better outcomes beyond simply prolonging ejaculation time.

Impact:

  • Highlights the underestimation of partner-related factors in PE management.
  • Suggests that a comprehensive, evidence-based medical and/or psycho-sexological approach is warranted for distressed individuals.
  • Emphasizes the need for better diagnosis and treatment strategies for this common sexual dysfunction.
