Understanding Varicocele Treatment
A varicocele is a swelling of the veins within the scrotum, similar to varicose veins in the legs. It is a common cause of male infertility and testicular discomfort. Treatment can relieve pain and improve sperm quality.

What Is Varicocele?
Varicoceles occur when valves in the veins along the spermatic cord fail, causing blood to pool and veins to enlarge. They are most commonly found on the left side and may impair testicular function and sperm production.

How Varicocele Is Diagnosed
Varicocele evaluation typically includes:
Treatment Options & Related Procedures
Treatment is recommended when a varicocele causes pain, testicular shrinkage, or fertility concerns. The most suitable approach depends on age, symptoms, semen findings, and individual goals.
Appropriate for patients who have no discomfort and are not seeking fertility treatment. Regular monitoring with physical examination and ultrasound helps ensure that the varicocele is stable.
Supportive measures such as wearing snug-fitting underwear or a scrotal support can relieve mild discomfort. Short courses of anti-inflammatory medication may also help reduce swelling and pain.
This is the most common and effective treatment for symptomatic or fertility-related varicocele. It involves tying off and dividing the enlarged veins so that blood flow is redirected through healthy vessels. Depending on the condition, the procedure can be performed through a laparoscopic (keyhole) or microsurgical approach. Both aim to preserve the artery and lymphatic drainage to minimise complications and recurrence.
Performed by an interventional radiologist under local anaesthesia and mild sedation. A fine catheter is inserted through a small puncture in the groin to block the affected veins with coils or agents, rerouting blood to normal pathways. This option is suitable for selected patients who prefer a minimally invasive, outpatient procedure.

Frequently Asked Questions
Yes. It may impair sperm quantity and quality. Varicocele has also been associated with decline in and testosterone production in later life.
No. Surgery is recommended for symptomatic cases (pain or swelling in scrotum) or those with infertility.
Surgery should be done early in a teenager even if he does not experience pain but if the testis size was confirmed to be smaller. Early correction of varicocele would allow the affected testis to grow to its full potential.
No. However, heavy gym activities or straining may bring to attention a pre-existing varicocele as the activities would induce congestion and pain in the scrotum.
