This material was prepared by a urologist with many years of clinical experience in treating prostate diseases and acute urological conditions. The article draws on clinical practice data, classical and modern scientific sources, as well as current European guidelines.

Prostatitis is one of the most common causes of urological discomfort in men: perineal pain, urinary disturbances, a feeling of heaviness, and flare-ups after hypothermia or stress. But prostate inflammation does not develop “out of nowhere”: it has specific mechanisms, predisposing conditions, and factors that genuinely increase the risk of disease.

In this article, we will look at why prostatitis develops, which causes are considered clinically significant, and why it is important to distinguish infectious processes from congestive and chronic forms of inflammation when making a proper clinical assessment.

At the beginning, it is worth briefly explaining to the reader what the prostate gland is and what role it plays in the male body.

So, what is the prostate in men? It is an extremely important organ whose functional state affects полноценный sexual function, stable erection, quality of urination, and male reproductive potential.

The Prostate Gland: Structure, Functions, and Its Importance for Men’s Health

The anatomical location of the prostate gland and its direct connection to the urethra make it vulnerable to infectious and inflammatory diseases, including prostatitis.

One of the pioneers in prostatitis research, Stamey T. (1980), believed that half of all men experience prostatitis at least once in their lifetime. More recent international studies (Robertson C. et al., 1999) confirmed this assumption: 35% of surveyed men had symptoms of prostatitis during the previous year.

The impact of prostatitis on quality of life is significant and has been shown to be comparable to that of myocardial infarction, angina pectoris, and Crohn’s disease (Wenninger K., 1996).

Definition and Main Functions

The prostate gland (prostate) is an unpaired exocrine gland of the male reproductive system, and its anatomical location determines its main functions. It has a specific shape, enlarges with age, and partially changes in appearance over time. The prostate consists of glandular and muscular tissue. The glandular tissue produces hormones and prostatic fluid, while the muscular tissue regulates the lumen of the urethra.

The size of the organ largely depends on a man’s body type. On average, the prostate gland measures approximately: width – 3.5 cm, length – 3 cm, thickness – about 2 cm. Its weight usually does not exceed 20 g. In shape, the prostate resembles a walnut or a large chestnut. Its narrower pole surrounds the initial part of the urethra, while the broader part adjoins the lower portion of the bladder and surrounds its neck.

The functions of the prostate are multifaceted. The organ is responsible not only for stable sexual function and maintaining sperm fertility, but also for preventing semen from flowing back into the bladder and for the quality of urination. In other words, the condition of both the urinary and reproductive systems largely depends on how well the prostate functions. The prostate has both barrier and secretory functions. More on these below.

The Barrier Function of the “Second Male Heart”

The prostate acts as a kind of “checkpoint” that separates ejaculation from urination: the muscular part of the organ prevents semen from refluxing into the bladder, effectively acting as an involuntary sphincter. In addition, it is responsible for the quality of urination, helps retain urine, and ensures its normal outflow at the right time.

The prostate gland also protects the male reproductive tract from infections. It prevents microorganisms entering through the urinary tract from ascending into the upper urinary tract, thereby protecting against various infectious diseases.

The Secretory Function of the Gland and Its Role in Male Sexual Activity

The secretory function of the prostate gland is performed by its glandular component and includes:

  • the production of prostatic fluid, which affects semen quality
  • the production of biologically active substances – prostaglandins involved in pelvic blood supply and normal erectile function
  • the synthesis of male sex hormones: testosterone, enzymes, vitamins, immunoglobulins, citric acid, and prostate-specific antigen

Due to its rich innervation, the prostate contributes to pleasurable sensations during sexual intercourse. The secretion it produces helps liquefy ejaculate and supports normal sperm motility.

Factors That Trigger Prostatitis

Prostatitis has been spreading rapidly: there is a clear trend toward younger men being affected. Whereas prostatitis previously occurred mainly in men aged 35 and older, it is now increasingly seen in young men after the age of 20. So what can cause inflammation of the prostate gland, an organ seemingly so well protected deep within the pelvis?

Predisposing Factors for the Development of Prostatitis

  • structural features of the prostate gland that contribute to stagnation of prostatic secretions in the gland’s ducts
  • structural features of the venous network of the prostate gland that lead to blood stasis
  • hormonal imbalance (congenital pathology, uncontrolled use of hormonal medications)
  • structural features of neuro-reflex connections with the rectum and bladder
  • age-related changes in the prostate itself and in hormone levels
  • congenital reduction in immune defense

Contributing Factors to the Development of Prostatitis

  • Chronic Perineal Trauma (Prolonged Horseback Riding, Cycling)
  • Excessive Sexual Activity

It is worth noting that excessively intense sexual activity can negatively affect the functional state of the prostate gland. Sexual capacity, intensity, and patterns vary from one man to another. Sexual activity depends largely on physical and neuropsychological condition, as well as many external factors. Therefore, it is impossible to define a universal “normal” frequency of sexual intercourse. Each man should determine it individually, based on his own capabilities and well-being. It is also important to remember that during sexual intercourse and orgasm, all body systems are in a state of increased activity and therefore require greater nervous and energy expenditure.

The body can fully recover these expenditures if an individual physiological balance is maintained. However, if a man leads an excessively active sexual life that exceeds his physiological and psychological needs, this may be regarded as sexual excess. In some cases, a man may engage in daily sexual activity not because of an actual need, but as a result of artificial psychological or mechanical stimulation. Such a sexual pattern, when practiced over a long period or systematically with short intervals between sexual acts, may negatively affect the functional state of the prostate. Excessively frequent sexual intercourse may lead to functional disturbances of the reproductive system, impaired circulation, depletion of gonadal function, and reduced ejaculate volume. All of this may potentially have a negative impact on reproductive function and sexual health.

What Causes Prostatitis

Smoking and Alcohol

These two factors negatively affect the entire body, but alcohol is especially harmful to the prostate gland because it can cause swelling of prostatic tissue. Some men attempt to artificially enhance sexual desire with alcohol. However, although alcohol may increase desire, it simultaneously reduces male sexual performance.

Alcohol and smoking weaken the immune system, significantly reducing the body’s protective defenses. As a result, bacteria may enter the gland with much less resistance, which increases the risk of inflammation in the prostate.

Infections

Infectious agents include both gram-positive and gram-negative flora (E. coli, Proteus, Enterobacter, Klebsiella, and others). Incompletely treated chronic diseases in men may allow infection to spread from a primary focus to the prostate gland through hematogenous or lymphogenous routes. Common triggers of prostatitis include tonsillitis, bronchitis, herpes, sinusitis, and even dental caries. Various pathogenic bacteria can also enter the prostate from the rectum or through the urethra.

In recent years, the list of infectious diseases has also been supplemented by so-called “mutant diseases.” What does that mean? Due to worsening environmental conditions, poor nutrition, and widespread medication exposure, the body’s defenses may weaken, and pathogens of illnesses such as acute respiratory infections and herpes simplex virus may undergo adaptive changes. These pathogens can then contribute to prostatitis, urethritis, and other conditions when the body becomes more vulnerable. Even mild hypothermia may be enough to trigger their activation.

The most dangerous cause of prostatitis is sexually transmitted infection (chlamydia, ureaplasmosis, candidiasis, mycoplasmosis, gonorrhea, trichomoniasis, etc.). It often begins with urethritis – inflammation of the urethra. If treatment is not started in time, the inflammatory process may spread to the prostate gland, involve the pelvic organs, and ascend toward the kidneys, potentially causing pyelonephritis.

Bacteria and Viruses

  • Mycobacterium Tuberculosis
  • Viruses (Most Often Urogenital Herpes – Herpes Simplex Virus Type 2, Less Commonly Influenza Virus)
  • Immunological Disorders (Including Autoimmune Conditions)
  • Chemical Injury Due to Urinary Reflux
  • Neurogenic Disorders

Hypothermia

Hypothermia of the pelvic region. This can happen to anyone, but those especially at risk include people who enjoy winter fishing, extreme sports, or winter outdoor recreation. Prolonged exposure to drafts may also trigger the development or exacerbation of chronic prostatitis.

Sedentary or Low-Activity Lifestyle

Today, many male drivers and long-haul truckers suffer from what may be called an occupational condition. Sedentary office work also contributes to reduced blood circulation in the pelvic region, which leads to congestion in the prostate. When the prostate becomes engorged with blood, it effectively “suffocates.” As medicine says: where there is stagnation, there is inflammation.

Nervous and Physical Overstrain

Depression, stress, chronic fatigue, and persistent sleep deprivation all contribute to the development of inflammation in the prostate gland. Heavy physical exertion and overstrain during intensive sports activity can also negatively affect the prostate.

Irregular Sexual Activity

Irregular sexual activity may be another contributing factor. This is because during ejaculation, the prostate is naturally stimulated and effectively “massaged.” If the prostate gland remains inactive for a long time and therefore does not contract regularly, congestion may develop, tissue swelling may occur, and intratissue pressure may rise.

As a result, lymphatic and blood circulation may become impaired, disturbances in the neural regulation of the prostate may follow, and chronic inflammation may gradually develop. This is why congestive (chronic nonbacterial) prostatitis is sometimes informally referred to as a condition associated with prolonged sexual inactivity. Irregular sexual activity, especially when it follows a “periods of excess followed by long gaps” pattern, as well as unfulfilled sexual tension, may also contribute to pelvic blood stagnation and stagnation of prostatic secretions within the gland itself.

The main cause of prostatitis is the entry of infection into the gland, which is facilitated by the anatomical structure of the prostate gland. Infection may reach the prostate through the urethra, rectum, lymphatic pathways, or the bloodstream.

Why It Is Important to Get a Timely Urological Assessment

In many cases, inflammation of the prostate gland can be prevented. To do that, it is important to clearly understand what prostatitis is and what may cause it.

Inflamed prostate tissue changes its structure, and the functions of both the cells and the gland as a whole become impaired. This can lead to serious consequences, including reduced libido and erectile dysfunction, chronic pelvic pain syndrome, and urinary disorders. That is why it is important to notice symptoms in time and seek medical evaluation. The problem is that many men are afraid of this diagnosis and, even when they notice symptoms, try to delay seeing a doctor.

Unfortunately, many men tend to postpone acknowledging problems in the intimate area, let alone discussing them with a physician. As a result, they are left alone with the problem.

But these problems do not resolve on their own.
Sometimes men think their specific symptoms – perineal pain, painful and frequent urination, premature ejaculation – are random and temporary. Maybe they will go away on their own. Still, for some, this becomes a warning sign.

They understand that any dysfunction of the prostate gland, if not properly treated, may lead to serious sexual and urinary complications. They do understand it. But they still delay treatment. And a year or two later, they are already diagnosed with chronic prostatitis.

If urinary complaints, perineal pain, discomfort after hypothermia, or repeated flare-ups keep returning, it is important not to simply “wait it out” and not to rely only on advice from the internet. For the prostate, timely clinical assessment is especially important: the earlier the true cause of symptoms is identified, the greater the chance of avoiding prolonged inflammation, chronic pelvic pain, and lengthy treatment.
