Varicocele

Varicocele is a pathology characterized by the expansion of the veins of the spermatic cord, which leads to a violation of the venous outflow of blood from the testicle. This condition can be associated with deterioration of spermatogenesis and, as a result, with infertility in men. Varicocele is often observed on one side, most often on the left, which is due to the anatomical features of the venous system. This disease can be asymptomatic or accompanied by pain in the scrotum, a feeling of heaviness or discomfort. It is important to note that despite the prevalence of varicocele, many men are unaware of the presence of this pathology, which explains the importance of its early diagnosis and timely treatment.

History of the disease and interesting historical facts

The history of studying varicocele goes back several centuries. The first mention of this pathology can be dated back to the 4th century BC, when Hippocrates described conditions similar to varicose veins. For centuries, the disease remained in the shadows until its thorough study began in the 20th century. In the 1940s, the era of surgical treatment began when Ernst K. Bruggeman first proposed a method of ligating the testicular veins to reduce venous pressure in the spermatic cord. Studies were also conducted confirming the connection between varicocele and male infertility, which sparked new interest in this pathology. In other countries, such as India and China, varicocele was known in traditional medical systems, where various treatment methods were used, including herbal medicine and acupuncture.

Epidemiology

Varicocele accounts for 15-20% of all cases of men seeking help for infertility. According to statistics, this disease is detected in 40% of men with fertility problems. In the adolescent population, the frequency of varicocele ranges from 51% to 101%, and this figure increases with age. For example, at the age of 30, varicocele occurs in 151% of men, and in men over 50, its prevalence reaches 301%. Global studies show significant differences in the frequency of varicocele among different ethnic groups and residents of different regions, indicating the possible influence of genetic and environmental factors.

Genetic predisposition to this disease

Existing studies confirm that varicocele may have a genetic predisposition. Certain mutations and polymorphisms of genes responsible for the synthesis of collagen and other components of connective tissue may predispose to the development of this condition. Associations have also been identified between varicocele and genes responsible for venous tone and the matrix of the extracellular space, such as the MGMT and SKKD genes. These data open new horizons for further study of the molecular mechanisms of varicocele and its relationship to infertility.

Risk factors for the development of this disease

There are many factors that contribute to the development of varicocele. The main ones include:

• Anatomical features of the venous system: right-sided and left-sided anomalies.
• Chronic diseases (pneumonia, tuberculosis) that can provoke an increase in pressure in the abdominal cavity.
• Physical activity: weightlifting or long-term cycling.
• Chemical factors: exposure to toxic substances such as heavy metals and certain medications taken into account in medicine.
• Hereditary predisposition: the presence of varicocele in close relatives increases the risk of developing the pathology.

Diagnosis of this disease

Diagnosis of varicocele includes several stages, including:

• General examination: assessment of the condition of the scrotum, palpation of the spermatic cord to detect dilated veins.
• Laboratory tests: sperm analysis for quality and quantity of sperm, determination of hormonal levels.
• Radiological examinations: ultrasound diagnostics (ultrasound) with Dopplerography to assess blood flow in the veins.
• Other types of diagnostics: thermography or MRI to exclude other diseases.
• Differential diagnosis: exclusion of “end of thrombus” syndrome and other pathologies.

Treatment

Varicocele treatment can be conservative and surgical. Conservative measures include:

• Pharmacological treatment: administration of analgesics and anti-inflammatory drugs.
• Physiotherapy: the use of methods aimed at improving blood circulation.
• Wearing supportive underwear: This reduces pressure on the scrotal area.

Surgical treatment is often the most effective method and includes:

• Pirogov's operation: ligation of the affected vein.
• Endovascular embolization: A minimally invasive procedure performed through a catheter.
• Laparoscopic methods: allow for quick recovery after surgery.

List of medications used to treat this disease

The main medications recommended for varicocele include:

• Nonsteroidal anti-inflammatory drugs (eg, Ibuprofen).
• Venotonics (for example, Detralex).
• Preparations to improve microcirculation (for example, Trental).
• Hormonal drugs in case of testosterone deficiency.

Disease monitoring

Monitoring of patients with varicocele includes regular examinations and symptom control. The main control stages are:

• Repeat sperm analysis 6-12 months after treatment to assess effectiveness.
• Preventive examinations by a urologist to detect relapses.
• Evaluation of possible complications such as development of testicular atrophy or secondary infections.

The prognosis for varicocele with adequate treatment is usually favorable, but advanced cases can lead to infertility, which requires further intervention.

Age-related features of the disease

Varicocele can manifest itself in different age groups. In adolescents, the pathology is often diagnosed during puberty. In young men (up to 30 years old), the disease can be associated with fertility problems. In adulthood (30-50 years old), varicocele is often detected by chance, during examination for other reasons. In older men over 50 years old, the likelihood of symptoms increases, and the risk of complications such as infertility and pain is high.

Questions and Answers

• What are the main symptoms of varicocele? The main symptoms include pain or discomfort in the scrotum, enlargement of the veins of the spermatic cord, and deterioration in sperm quality.
• What are the most effective treatments for varicocele? Surgical treatment, including vein ligation and endovascular embolization, is the most effective treatment for varicocele.
• How often should you undergo examination for varicocele? It is recommended to undergo examination annually and also after any changes in condition or symptoms.
• Can varicocele affect sexual function? Varicocele can negatively affect erectile function, but this depends on the individual characteristics of the patient.
• Is it possible to avoid varicocele? It is impossible to completely prevent varicocele, but maintaining a healthy lifestyle and avoiding risk factors can reduce the likelihood of its occurrence.
