Microsurgical Varicocelectomy (Varicocele Treatment)
Microsurgical varicocelectomy is a surgical treatment used to repair a varicocele – enlarged veins within the scrotum. The procedure can help relieve discomfort, improve fertility, and support testicular health.
What is microsurgical varicocelectomy?
A varicocele is a group of enlarged veins inside the scrotum, similar to varicose veins that can develop in the legs. Varicoceles are common and often develop during puberty. They usually occur on the left side of the scrotum, although some men can develop them on both sides.
Many varicoceles don’t cause symptoms and may not require treatment. However, some can lead to:
aching or heaviness in the scrotum
discomfort that worsens after standing or exercise
testicular shrinkage (atrophy)
abnormal semen quality
Microsurgical varicocelectomy is considered the gold-standard surgical treatment for varicoceles. During the procedure, a consultant urological surgeon uses a high-powered operating microscope to identify and seal the enlarged veins while carefully preserving important structures, including arteries, lymphatic vessels, and the vas deferens.

More information
Before surgery, you’ll attend a consultation with one of our urology specialists. Your consultant will discuss your symptoms, medical history, fertility concerns, and any previous investigations, such as ultrasound scans or semen analysis.
Microsurgical varicocelectomy is usually performed as a day-case procedure under general anaesthetic, meaning you can normally return home on the same day.
The procedure involves the following steps:
Your surgeon makes a small incision in the groin area, just above the scrotum.
Using an operating microscope, the enlarged veins are carefully identified.
The abnormal veins are tied off or sealed to redirect blood flow into healthy veins.
Important structures, including arteries and lymphatic vessels, are preserved.
The incision is closed using dissolvable stitches or surgical glue.
The surgery usually takes between 1 and 2 hours, depending on whether one or both sides require treatment.
Because the procedure uses microsurgical techniques, it offers excellent precision and has lower rates of recurrence and complications compared with older surgical methods.
Your consultant may recommend microsurgical varicocelectomy if a varicocele is causing symptoms or affecting your fertility.
Common reasons for treatment include:
persistent scrotal pain or discomfort
fertility problems linked to abnormal semen analysis
reduced testicular size
a large or visible varicocele
symptoms that interfere with exercise or daily activities
concern about declining testicular function
Not everyone with a varicocele requires surgery. Your consultant will discuss whether treatment is appropriate for your symptoms, age, fertility goals, and overall health.
Microsurgical varicocelectomy is considered a safe and effective procedure, particularly when performed by an experienced specialist surgeon. However, as with any surgery, there are some risks and possible complications.
These can include:
bleeding or bruising
infection
temporary swelling or discomfort
recurrence of the varicocele
fluid build-up around the testicle (hydrocele)
injury to nearby structures, including arteries (risk is reduced with this microscopic approach)
numbness around the incision site
ongoing pain despite treatment
Serious complications are uncommon. Microsurgical techniques significantly reduce the risk of complications such as hydrocele formation and damage to the testicular artery.
Your consultant will explain the potential risks and benefits of surgery during your consultation and answer any questions you may have.
Your consultant will provide detailed instructions before your procedure to help make sure your surgery and recovery go smoothly.
Preparation may include:
having blood tests or imaging scans
stopping certain medications before surgery, if advised
fasting for several hours before the procedure
arranging for someone to take you home afterwards
wearing loose, comfortable clothing on the day of surgery
If fertility is a concern, your consultant may recommend semen analysis before treatment to assess sperm quality and help monitor improvement after surgery.
It’s important to tell your consultant about any medications, allergies, or medical conditions before the procedure.
Most patients return home on the same day as their surgery once they’ve recovered from the anaesthetic.
It’s normal to experience mild pain, swelling, or bruising around the groin and scrotum for a few days afterwards. This usually improves gradually and can be managed with over-the-counter pain relief such as paracetamol or ibuprofen, if suitable for you.
To support recovery, your consultant may advise you to:
rest for the first 24 to 48 hours
wear supportive underwear to reduce discomfort
avoid strenuous exercise and heavy lifting for around 2 weeks
avoid sexual activity for 1 to 2 weeks
keep the wound clean and dry
avoid swimming and hot tubs until the wound has healed
Most people can return to desk-based work within a few days. Jobs involving physical activity may require more recovery time. You should not drive for at least 24 hours after a general anaesthetic.
Your consultant will usually arrange a follow-up appointment to check your recovery. If fertility was one of the reasons for treatment, further semen analysis may be recommended after several months, as improvements in sperm quality can take time.

Frequently asked questions
Yes, although recurrence after microsurgical varicocelectomy is uncommon. Microsurgical techniques have lower recurrence rates than many other forms of varicocele treatment because the enlarged veins can be identified more accurately during surgery.
Many men will have improvements in their sperm count, sperm motility, or sperm quality after surgery. However, results vary from person to person, and improvement may take several months. Your consultant will discuss the likelihood of fertility improvement based on your individual situation.
You’ll be asleep during the procedure under general anaesthesia, so you won’t feel anything. After surgery, most patients experience mild to moderate discomfort rather than severe pain. This is usually temporary and improves within a few days.
Some varicoceles don’t cause problems and can simply be monitored. However, in some cases, untreated varicoceles may lead to worsening discomfort, reduced fertility, or gradual shrinkage of the affected testicle. Your consultant can advise whether treatment is recommended for you.
