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...
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...
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...
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...
Infertility in Males01:23

Infertility in Males

Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Summary
This summary is machine-generated.

Premature ejaculation (PE) is a common male sexual dysfunction affecting up to 30% of men. Due to its personal nature, many affected individuals do not seek professional medical help.

Area of Science:

  • Urology
  • Sexual Health
  • Men's Health

Background:

  • Premature ejaculation (PE) is recognized as the most prevalent male sexual dysfunction globally.
  • International studies indicate PE affects a significant percentage of the male population, estimated between 14% and 30% of men aged 18 and above.

Purpose of the Study:

  • To highlight the high prevalence of premature ejaculation (PE) as a common male sexual dysfunction.
  • To underscore the barriers preventing affected individuals from seeking professional medical assistance for PE.

Main Methods:

  • This study is based on a review of international research and epidemiological data concerning male sexual dysfunction.
  • Analysis of existing literature to determine the prevalence rates and contributing factors of PE.

Main Results:

  • Premature ejaculation (PE) affects a substantial proportion of adult males, with prevalence rates ranging from 14% to 30% in international studies.
  • A significant disparity exists between the high prevalence of PE and the low rate of professional help-seeking behavior among affected individuals.

Conclusions:

  • Premature ejaculation (PE) represents a widespread health concern among adult men.
  • Hesitancy from both patients and healthcare providers to discuss PE contributes to underdiagnosis and undertreatment, necessitating greater awareness and open communication.
