Varicocelectomy
What is a Varicocelectomy?
A varicocelectomy is a surgical procedure performed to treat a varicocele, which is an enlargement of the veins within the scrotum that drain blood from the testicle. Varicoceles are similar to varicose veins in the legs and most commonly occur on the left side, although they can affect both sides.
The procedure involves tying off or sealing the affected veins so that blood is redirected through healthy veins. This improves blood flow, reduces pressure around the testicle, and may relieve pain, improve fertility, or help preserve testicular function.
What are the Benefits of a Varicocelectomy?
For appropriately selected patients, a varicocelectomy can provide both symptom relief and long-term reproductive benefits.
Benefits include:
- Relieves chronic testicular discomfort caused by a varicocele
- Improves blood flow around the testicle
- May improve sperm count, movement, and quality
- Can enhance fertility in selected men
- May prevent further testicular shrinkage (atrophy)
- Minimally invasive techniques are available
- Usually performed as a day-case procedure
- Long-lasting treatment with a low recurrence rate when performed using microsurgical techniques
When is a Varicocelectomy Recommended?
Not every varicocele requires surgery. Many are harmless and cause no symptoms.
A varicocelectomy may be recommended for:
- Persistent testicular pain caused by a varicocele
- Male infertility associated with an abnormal semen analysis
- Testicular shrinkage or poor testicular growth
- A large, clinically significant varicocele
- Young men with evidence of impaired testicular development
- Patients with discomfort that has not improved with conservative measures
Your urologist will determine whether surgery is appropriate based on your symptoms, fertility goals, examination findings, and imaging results.
What does Preparation for a Varicocelectomy Involve?
Before surgery, your urologist will assess your condition and discuss the most suitable treatment approach.
Preparation may include:
- Medical history and physical examination
- Scrotal ultrasound to confirm the diagnosis
- Semen analysis if fertility is a concern
- Blood tests if required
- Review of current medications, including blood-thinning medicines
- Fasting before general anaesthetic
- Discussion of the procedure, expected recovery, and possible risks
Patients considering surgery for infertility may also receive counselling regarding fertility outcomes and alternative treatment options.
How is a Varicocelectomy Performed?
A varicocelectomy is usually performed under general anaesthetic and typically takes between 45 and 90 minutes.
Several surgical techniques are available, although the microsurgical subinguinal approach is widely considered the preferred method because of its high success rate and low complication rate.
During the procedure, the surgeon makes a small incision in the groin or lower abdomen. Using magnification provided by an operating microscope, the enlarged veins supplying the varicocele are carefully identified and tied off while preserving the arteries, lymphatic vessels, and vas deferens. This allows blood to be redirected through normal healthy veins, reducing pressure around the testicle.
In some cases, the procedure may be performed laparoscopically through several small abdominal incisions. Another alternative, known as percutaneous embolisation, is performed by an interventional radiologist rather than a surgeon and is not considered a varicocelectomy.
Once the abnormal veins have been divided, the incision is closed with dissolvable or removable stitches, and a dressing is applied.
What to Expect during Recovery after a Varicocelectomy?
Most patients return home on the day of surgery.
During recovery, you may experience:
- Mild groin or scrotal discomfort
- Swelling or bruising around the incision
- Temporary tenderness of the testicle
- A gradual return to normal walking within one to two days
- Avoidance of strenuous exercise and heavy lifting for approximately two to four weeks
- Wearing supportive underwear to improve comfort
Most men return to office-based work within several days, while more physically demanding occupations may require a longer recovery period.
If the procedure is performed to improve fertility, semen quality generally begins to improve over the following three to six months, as sperm production naturally takes time.
What are the Risks and Complications of a Varicocelectomy?
Varicocelectomy is a safe and commonly performed procedure, but all surgery carries potential risks.
Possible complications include:
- Bleeding
- Infection
- Bruising or swelling
- Recurrence of the varicocele
- Fluid collection around the testicle (hydrocele)
- Persistent or recurrent testicular pain
- Injury to the testicular artery, although uncommon
- Temporary numbness around the incision
- Blood clots, although rare
- Failure to achieve the desired improvement in fertility
Your urologist will explain whether a varicocelectomy is appropriate for your condition, discuss the expected benefits and possible risks, and recommend the treatment approach best suited to your symptoms and reproductive goals.
