🔹 Varicocele: Causes, Symptoms, Diagnosis, and Treatment
What is a Varicocele?
A varicocele is an enlargement of the veins within the scrotum, the pouch that holds the testicles. It is similar to varicose veins that can occur in the legs.
This condition affects about 10% of men, and up to 30% of men with fertility problems.
Varicoceles most commonly occur on the left side of the scrotum (about 90% of cases), while bilateral varicoceles appear in around 10%, and rarely affect the right side alone.
Causes of Varicocele
Varicocele develops when the valves inside the veins that carry blood from the testicles to the heart become weak or fail to function properly, leading to blood pooling and vein dilation.
Common contributing factors include:
-
Genetic predisposition (family history of varicose veins).
-
Prolonged standing or physical strain.
-
Increased abdominal pressure, often due to chronic constipation or heavy lifting.
-
Abnormal blood flow from the kidneys or abdominal veins.
Symptoms of Varicocele
In many cases, varicocele causes no noticeable symptoms. However, some men may experience:
-
A dull, aching pain or heaviness in the scrotum that worsens with standing or physical activity.
-
Visible or palpable swelling on the left side of the scrotum.
-
Testicular atrophy (shrinking) in the affected side.
-
Fertility issues, including low sperm count or poor sperm quality.
Complications of Varicocele
If left untreated, a varicocele can lead to several complications, such as:
-
Reduced sperm production and quality.
-
Testicular tissue damage over time.
-
Infertility or delayed conception.
-
Changes in testicular size or appearance.
Diagnosis of Varicocele
Diagnosis usually involves:
-
Physical examination – The doctor examines the scrotum while the patient is standing or performing the Valsalva maneuver.
-
Scrotal ultrasound (Doppler imaging) – To assess the size of the veins and blood flow.
-
Semen analysis – To evaluate the effect on fertility.
Treatment Options for Varicocele
Treatment depends on the severity of the condition and its impact on fertility. Options include:
-
Observation and follow-up for mild cases without symptoms.
-
Surgical ligation (varicocelectomy) – The most common treatment, performed through traditional surgery or laparoscopy to tie off affected veins.
-
Percutaneous embolization (catheter procedure) – A minimally invasive option that blocks the damaged vein without surgery.
After treatment, blood flow improves, and sperm quality often increases within several months.
Prevention and Care
While there is no guaranteed way to prevent varicocele, the following measures may help reduce risk:
-
Avoid standing for long periods.
-
Engage in regular exercise to improve circulation.
-
Maintain a healthy body weight.
-
Seek medical advice if you notice scrotal pain or swelling.
