Testicles

The testicles (testis) are a pair of oval-shaped organs located within the scrotum, responsible for producing sperm and the hormone testosterone.

Understanding The Testicles

Testicular health is crucial for male fertility and general well-being. Various conditions can affect the testes, causing pain, swelling, or changes in testicular function.

Overview

  • Testicular cancer is a type of cancer that originates in the cells of the testes, most commonly affecting young and middle-aged men. It is generally highly treatable, especially when detected early.

 

Causes

  • While the exact cause of testicular cancer is unknown, certain factors can increase the likelihood of developing the condition.

 

Symptoms

  • A lump or swelling in the testicle, often painless
  • A feeling of heaviness or aching in the scrotum or lower abdomen
  • Changes in testicle size or shape
  • Back pain or discomfort in advanced stages

 

Risk Factors

  • Age: Most common in men between 15 and 35 years.
  • Undescended Testicle (Cryptorchidism): Men with a history of an undescended testicle are at higher risk.
  • Family History: Having a close relative with testicular cancer increases risk.
  • Personal History: Men who have had testicular cancer in one testicle are at higher risk of developing it in the other.

 

Treatment Options

  • Surgery: Orchiectomy (removal of the affected testicle) is usually the first step in treatment.
  • Radiation Therapy: Often used to target remaining cancer cells, especially in seminoma-type cancers.
  • Chemotherapy: Recommended for advanced or recurrent cancer to kill cancer cells throughout the body.
  • Surveillance: Regular monitoring may be recommended after initial treatment to detect any recurrence.

Overview

  • Epididymitis is inflammation of the epididymis, a coiled tube at the back of each testicle that stores and carries sperm. It is often caused by bacterial infections, including sexually transmitted infections (STIs).

 

Causes

  • Bacterial Infections: Commonly due to STIs, such as chlamydia or gonorrhoea, in sexually active men.
  • Urinary Tract Infections (UTIs): Bacteria from the urinary tract can spread to the epididymis.
  • Trauma or Injury: Physical injury to the scrotum can lead to inflammation.

 

Symptoms

  • Pain and swelling in one or both testicles
  • Tenderness in the scrotum, sometimes radiating to the groin area
  • Fever and chills in more severe cases
  • Pain during urination or ejaculation

 

Risk Factors

  • Age: Common in young, sexually active men under 35.
  • Unprotected Sex: Increases risk of contracting STIs.
  • Prostate or Urinary Tract Issues: Conditions that increase urinary tract infections can lead to epididymitis.

 

Treatment Options

  • Antibiotics: The primary treatment for bacterial epididymitis.
  • Pain Management: Pain relief through over-the-counter pain relievers and scrotal support.
  • Ice Packs: Applying ice packs to the scrotum can reduce swelling and discomfort.
  • Prevention: Using protection during sexual activity and practising good hygiene can lower risk.

 

Overview

  • Testicular torsion is a medical emergency in which the spermatic cord, which supplies blood to the testicle, becomes twisted, cutting off the blood supply. If untreated, it can lead to permanent damage or loss of the testicle.

 

Causes

  • Congenital Abnormalities: Conditions such as the “bell-clapper deformity” make the testes more prone to twisting.
  • Sudden Movement or Trauma: Physical activity, injury, or sudden movement can sometimes trigger torsion in susceptible individuals.

 

Symptoms

  • Severe, sudden pain in one testicle, often accompanied by nausea or vomiting
  • Swelling and tenderness in the affected testicle
  • Abdominal pain or discomfort
  • A testicle positioned higher than usual or at an unusual angle

 

Risk Factors

  • Age: Most common in boys aged 12-18 but can occur at any age.
  • Family History: Having a family member who had testicular torsion can increase risk.
  • Cold Weather: Sudden temperature changes may trigger torsion in some cases.

 

Treatment Options

  • Emergency Surgery: Surgery to untwist the spermatic cord and restore blood flow must be performed quickly to prevent permanent damage.
  • Orchiopexy: The affected and sometimes the unaffected testicle are surgically anchored to prevent future torsion.

Overview

  • A hydrocele is a painless swelling of the scrotum caused by an accumulation of fluid around one or both testicles. It is common in newborns but can also develop in adults, often resolving on its own.

 

Causes

  • Congenital Factors: In infants, hydroceles are often due to the incomplete closure of the abdominal cavity.
  • Injury or Inflammation: Trauma, infections, or inflammatory conditions can lead to hydrocele in adults.

 

Symptoms

  • Swelling in one or both sides of the scrotum
  • A feeling of heaviness in the scrotum
  • Discomfort or pain with larger hydroceles, particularly after prolonged activity

 

Risk Factors

  • Age: Common in newborns and older men.
  • Scrotal Injury or Infection: Increases risk of hydrocele development.
  • Previous Surgery: Men who have had groin surgery are at increased risk.

 

Treatment Options

  • Observation: Small hydroceles that are not causing discomfort may be monitored.
  • Aspiration: Fluid may be drained using a needle, though this is typically a temporary solution.
  • Surgery (Hydrocelectomy): Surgical removal of the hydrocele may be recommended if it causes discomfort or does not resolve on its own.

Overview

  • A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins in the legs. It can affect testicular function, potentially impacting fertility.

 

Causes

  • The exact cause is unclear, but varicoceles form when blood flow through the testicular veins is disrupted, causing them to widen and swell.

 

Symptoms

  • Dull, aching pain in the scrotum, often worsening throughout the day
  • Visible or palpable enlarged veins in the scrotum
  • Testicular atrophy (shrinking) in severe cases
  • Fertility issues in some cases

 

Risk Factors

  • Age: Common in adolescents and young men.
  • Standing for Long Periods: May exacerbate symptoms due to increased pressure in the scrotal veins.
  • Body Weight: Excess weight may affect vein function and pressure.

 

Treatment Options

  • Observation: Often, varicoceles do not require treatment unless they cause pain or fertility issues.
  • Pain Management: Over-the-counter pain relief and wearing supportive underwear can help.
  • Surgery (Varicocelectomy): Surgical options to seal the affected veins are available for severe cases or when fertility is impacted.
  • Embolisation: A minimally invasive procedure to block off the affected vein, improving blood flow in the scrotum.

Testicular Health and Prevention

Regular self-examination and maintaining general health are key to testicular health.

Men should perform monthly self-examinations to check for any unusual lumps, swelling, or changes in the testes, as early detection greatly improves treatment outcomes. Healthy lifestyle practices, such as maintaining a balanced diet, avoiding smoking, and using protection during sexual activity, are beneficial for testicular health.

If any unusual symptoms, pain, or swelling occur, consult a healthcare provider promptly for assessment.
