Varicocele Surgery

Introduction

If you are reading this, you have most likely been told that you have a varicocele — enlarged veins in the scrotum — and you are now thinking about surgery. The reason may be discomfort, a visible bulge, a difference in testicle size, or, most often, a semen analysis that came back abnormal during fertility testing. Whatever brought you here, you are at a point where the question is no longer “what is this?” but “what should I do about it?”

Varicocele surgery, also called varicocelectomy, is one of the most studied procedures in male reproductive medicine. It is not the right answer for every man with a varicocele, but for carefully selected patients it can ease symptoms, protect testicular function, and improve sperm quality over time. This guide explains what the surgery is, the different approaches doctors use, how to prepare, what to expect during recovery, and how to think about results — whether your goal is relief from pain, protection of testicular growth in adolescence, or improving the chance of pregnancy.

The article is written for adults considering surgery for themselves and for parents of teenage boys for whom a varicocele has been found. It does not replace a conversation with a urologist or fertility specialist, but it should help you walk into that conversation better prepared.

What Is Varicocele Surgery?

A varicocele is an abnormal enlargement of the pampiniform plexus — the network of veins that drains blood from the testicle. It is similar to varicose veins in the legs. When the small one-way valves inside these veins fail, blood pools, the veins stretch, and a soft “bag of worms” can sometimes be felt in the scrotum, usually on the left side. Varicoceles affect roughly 15 percent of men in the general population and a higher proportion of men evaluated for infertility.

Varicocele surgery, or varicocelectomy, is a procedure that interrupts the abnormal veins so that blood is rerouted through healthy drainage pathways. The arteries that supply the testicle, the lymphatic vessels, and the vas deferens (the tube that carries sperm) are deliberately preserved. The aim is to lower the temperature inside the scrotum, reduce pressure and back-flow of blood, and create a healthier environment for sperm production and testicular function.

A related, non-surgical option is varicocele embolization, in which an interventional radiologist threads a thin catheter into the affected vein and blocks it from the inside using coils or a sclerosing agent. Both surgery and embolization aim to achieve the same end result — stopping abnormal blood flow through the dilated veins.

Why Is Varicocele Surgery Performed?

Not every varicocele needs treatment. Many men have one and never know it. Surgery is usually considered for one or more of the following reasons.

Male-factor infertility

This is the most common reason for varicocele surgery in adult men. Joint guidance from the American Urological Association (AUA) and the American Society for Reproductive Medicine (ASRM), as well as the European Association of Urology (EAU), describes varicocele repair as an option to consider when all of the following are present: a couple is trying to conceive, the varicocele can be felt on physical examination (a “clinical” or palpable varicocele), the man has one or more abnormal semen parameters, and the female partner has either normal fertility or a potentially treatable cause of infertility.

Surgery is generally not recommended for varicoceles that can only be seen on ultrasound but cannot be felt (subclinical varicoceles), because the evidence that treatment helps in those cases is weak.

Pain or discomfort

A varicocele can cause a dull ache, a dragging sensation, or heaviness in the scrotum, often worse at the end of the day, in hot weather, or after standing or exercising. When pain is clearly linked to the varicocele and does not improve with conservative measures such as supportive underwear and pain relievers, surgery is one of the options doctors consider.

Testicular shrinkage in adolescents

In teenagers, doctors look closely at testicular size. If the testicle on the side of the varicocele is significantly smaller than the other side, or if testicular growth is falling behind, surgery may be recommended to protect future fertility and hormone production.

Abnormal hormone levels

Some men with varicoceles have lower-than-expected testosterone levels. Repair has been shown in studies to improve testosterone modestly in selected patients, although this is a secondary rather than primary indication.

Recurrence after previous treatment

If a varicocele returns after earlier surgery or embolization and is again causing symptoms or affecting sperm quality, a repeat procedure may be considered, often using a different technique.

Who Is a Candidate?

Whether varicocele surgery is appropriate is a clinical decision based on several factors. Doctors typically weigh:

• Whether the varicocele can be felt during a careful physical examination, not just seen on ultrasound
• The grade of the varicocele (grade 1, 2, or 3, based on how prominent it is)
• Semen analysis results, repeated on at least two occasions
• Hormone levels, especially testosterone and follicle-stimulating hormone (FSH)
• Your age and, in adolescents, testicular size and growth
• The duration of infertility and the female partner’s fertility status
• Whether you have pain that has not responded to simpler measures
• Your overall health and fitness for anaesthesia

Men who are unlikely to benefit include those with subclinical varicoceles, those with normal semen parameters and no symptoms, and men whose infertility is mainly due to a severe female factor that will need IVF regardless. Even in these cases, however, some couples and their doctors choose surgery if there is a desire to improve overall sperm quality before assisted reproduction.

Alternatives to Varicocele Surgery

Surgery is not the only option, and in many situations it is not the first one tried.

Watchful waiting

For a man with a small, painless varicocele and a normal semen analysis, doctors often recommend simply monitoring with periodic semen tests and physical examinations. Many varicoceles never cause a problem.

Conservative measures for pain

For mild discomfort, supportive underwear (such as snug briefs or an athletic supporter), over-the-counter pain relievers, avoiding prolonged standing, and limiting heat exposure (hot baths, saunas, long cycling sessions) can be enough.

Varicocele embolization

Embolization is a non-surgical alternative performed by an interventional radiologist. Through a small puncture, usually in a vein in the groin or neck, a thin catheter is guided up to the affected testicular vein and the vein is blocked from the inside using coils, plugs, or a sclerosing agent. Embolization avoids a scrotal or groin incision, has a quicker return to normal activity, and can be useful when varicoceles have recurred after surgery. The trade-off is that recurrence rates can be slightly higher than with microsurgical repair, and exposure to X-rays and contrast dye is involved.

Assisted reproductive technology

For couples whose main goal is pregnancy, intrauterine insemination (IUI), in vitro fertilisation (IVF), or IVF with intracytoplasmic sperm injection (ICSI) can be considered instead of, or in addition to, varicocele repair. The choice depends on sperm parameters, the woman’s age and fertility, and how much time the couple has. Some specialists recommend varicocele repair first when sperm quality is poor but not severely so, because improvements in sperm count, motility, and DNA integrity may allow a less intensive fertility treatment, or improve the chances of success if assisted reproduction is still needed later.

Hormonal and lifestyle measures

If hormonal imbalances or lifestyle factors are also contributing to poor sperm quality — obesity, smoking, heavy alcohol use, anabolic steroid use, certain medications, or significant heat exposure — addressing these is part of the overall plan, with or without surgery.

Surgical Approaches

Several surgical and procedural approaches exist. Each has its own access route, level of magnification, and trade-offs around recurrence and complications. Major urology societies, including AUA/ASRM and EAU, currently describe microsurgical subinguinal or inguinal varicocelectomy as the approach with the most favourable balance of low recurrence and low complication rates, though other techniques remain in use depending on anatomy and surgeon expertise.

Microsurgical subinguinal varicocelectomy

This is performed through a small (typically 2–3 cm) incision just below the groin crease, using an operating microscope or high-magnification loupes. The surgeon carefully separates and ties off each abnormal vein while preserving the testicular artery, lymphatic vessels, and vas deferens. Because the access is below the inguinal canal, the surgery avoids opening the abdominal wall muscles. It has the lowest reported rates of recurrence and of post-operative hydrocele (fluid build-up around the testicle).

Microsurgical inguinal varicocelectomy

Very similar to the subinguinal approach, but the incision is slightly higher and the inguinal canal is opened. This may be preferred when the anatomy below the canal is unfavourable or in revision surgery. Outcomes are comparable to the subinguinal approach when performed by experienced microsurgeons.

Open (non-microsurgical) inguinal or retroperitoneal varicocelectomy

Older open techniques, such as the Palomo (retroperitoneal, performed higher in the abdomen) and Ivanissevich (inguinal) procedures, tie off the testicular veins without magnification. These approaches are quicker but tend to have higher rates of hydrocele formation and of accidentally tying off the testicular artery, because individual vessels are harder to identify without magnification. They remain in use in some centres, particularly for adolescents or where microsurgical facilities are not available.

Laparoscopic varicocelectomy

A laparoscopic approach uses small incisions on the abdomen and a camera to identify and clip the testicular veins higher up, near where they join the larger abdominal veins. It is most often considered for bilateral varicoceles (both sides), since both can be addressed through the same access. The trade-offs include the need for general anaesthesia, entry into the abdominal cavity, and a small risk of injury to nearby structures. Recurrence and hydrocele rates can be higher than with microsurgical techniques.

Percutaneous embolization

As described in the alternatives section, this is not strictly surgery, but it is often discussed alongside surgical approaches because it achieves the same goal. It is performed under local anaesthesia with sedation, avoids a scrotal or groin incision, and allows quick return to daily activities. It is a reasonable option for many men, particularly for varicoceles that have recurred after surgery.

How the approach is chosen

The choice depends on the reason for treatment (fertility versus pain versus adolescent testicular protection), whether one or both sides are affected, your anatomy, prior surgeries, and the surgeon’s training and experience. For fertility-focused repair in adult men, microsurgical varicocelectomy is the approach most often recommended in current guidelines because it has the most favourable profile for sperm outcomes and complication rates. For pain only, or for adolescents, other approaches may be equally suitable.

Preparing for Varicocele Surgery

Preparation has two purposes: making sure surgery is the right step, and making sure you are in the best possible shape for it.

Confirming the diagnosis

Your urologist or fertility specialist will examine you while you stand, and ask you to perform a Valsalva manoeuvre (bearing down) to make the varicocele more obvious. A scrotal ultrasound with Doppler study is often used to confirm the diagnosis, measure the veins, check testicular size, and rule out other problems.

Fertility evaluation

If fertility is the reason for surgery, expect:

• At least two semen analyses performed several weeks apart, since results can vary
• Hormone tests, typically including testosterone, FSH, and luteinising hormone (LH)
• A review of medical history, medications, and lifestyle factors that affect sperm
• Evaluation of your partner’s fertility, since decisions about timing and whether to pursue surgery, assisted reproduction, or both depend on the couple as a whole

In some cases, additional tests such as sperm DNA fragmentation may be discussed.

Pre-operative checks

Standard pre-operative checks include blood tests, an ECG if you are older or have heart concerns, and an anaesthesia review. You will be asked about medications, especially blood thinners, aspirin, and supplements that affect bleeding, which may need to be stopped beforehand.

Lifestyle preparation

For fertility outcomes specifically, doctors often advise:

• Stopping smoking and limiting alcohol
• Maintaining a healthy weight
• Avoiding excessive scrotal heat (hot tubs, prolonged laptop use on the lap, tight insulating clothing)
• Stopping any use of anabolic steroids or testosterone supplements, which suppress sperm production
• Discussing any prescription medications that affect fertility

Sperm cells take roughly 70–90 days to mature, so improvements from lifestyle changes and from surgery itself take months to show up on a semen analysis.

The day before and the day of surgery

You will usually be asked not to eat or drink for several hours before surgery. Shave or trim the area only if instructed; otherwise the surgical team will do this. Bring loose-fitting clothing and supportive underwear or a scrotal support for the journey home.

What Happens During Varicocele Surgery

The exact experience depends on the approach. The description below covers the most common scenario — a microsurgical subinguinal varicocelectomy — with notes on how laparoscopic and embolization procedures differ.

Anaesthesia

Microsurgical varicocelectomy can be performed under general anaesthesia, spinal/regional anaesthesia, or local anaesthesia with sedation, depending on the surgeon’s preference and your situation. Laparoscopic surgery requires general anaesthesia. Embolization is usually done under local anaesthesia with light sedation.

The procedure step by step

1. Incision. A small incision (around 2–3 cm) is made in the lower groin crease.
2. Locating the spermatic cord. The spermatic cord, which contains the testicular artery, veins, vas deferens, and lymphatic vessels, is brought up into view.
3. Microsurgical dissection. Using an operating microscope or high-power loupes, the surgeon carefully identifies and separates each abnormal vein, while preserving the artery (often using a Doppler probe to confirm its pulse) and the lymphatic vessels.
4. Ligation. Each abnormal vein is tied off with fine sutures or clips. Some surgeons also deliver the testicle through the incision briefly to identify additional small veins (gubernacular veins) that can cause recurrence if missed.
5. Closure. The spermatic cord is returned to its position and the incision is closed in layers, often with absorbable stitches and skin glue or a small dressing.

The procedure typically takes 45 to 90 minutes per side. Laparoscopic surgery involves three small abdominal incisions, insufflation of the abdomen with carbon dioxide gas, and clipping of the testicular veins higher up. Embolization is performed in an interventional radiology suite, with the catheter inserted into a vein in the groin or neck and X-ray guidance used to navigate to the testicular vein, which is then blocked with coils or sclerosant.

Bilateral surgery

If both sides are affected, both can usually be repaired in the same operation through separate small incisions.

Recovery and Healing

The first few days

Expect mild to moderate scrotal or groin discomfort, some bruising, and minor swelling. Pain is usually well controlled with paracetamol and a short course of anti-inflammatory medication, if not contraindicated. Ice packs (wrapped in cloth) applied for short periods can help with swelling on the first day or two. A scrotal support or snug briefs reduce movement and discomfort.

The first one to two weeks

• Most men return to desk-based work within 2–5 days
• Showering is usually allowed within 24–48 hours; avoid soaking in baths or pools until cleared
• Avoid heavy lifting, vigorous exercise, and cycling for at least 1–2 weeks, or as advised
• Sexual activity and ejaculation are usually resumed after 1–2 weeks, once comfortable
• A small amount of swelling or a firm area near the incision can persist for several weeks and usually settles on its own

Follow-up

A wound check is sometimes scheduled at 1–2 weeks. For men who had surgery for fertility reasons, follow-up semen analyses are typically performed at 3 months and again at 6 months, since sperm production cycles take around three months. Hormone levels and varicocele recurrence are assessed clinically.

Timeline for fertility improvements

Improvements in sperm count, motility, and shape generally become measurable around 3 months after surgery and may continue to improve for up to 12 months. For couples trying to conceive naturally, doctors often suggest waiting at least 3–6 months before reassessing fertility plans, depending on the woman’s age and the urgency of conceiving.

Risks and Complications

Varicocele surgery is considered safe, particularly when performed by surgeons experienced in microsurgical techniques. As with any procedure, there are risks. Knowing them helps you weigh the decision and recognise problems early.

Common, usually minor

• Pain, bruising, and mild swelling around the incision
• Small areas of numbness near the wound
• Temporary scrotal swelling

Less common but important

• Hydrocele: a fluid collection around the testicle, caused by accidental disruption of lymphatic vessels. Reported in a small percentage of cases and lower with microsurgical techniques. Small hydroceles often resolve on their own; larger ones may need treatment.
• Recurrence or persistence of the varicocele: reported in roughly 1–2 percent of microsurgical cases and somewhat higher with non-microsurgical or laparoscopic approaches.
• Testicular artery injury: uncommon with microsurgical techniques, where the artery is identified and preserved. Injury can in rare cases affect testicular function.
• Wound infection or bleeding: uncommon and usually treated with antibiotics or simple measures.
• Testicular atrophy (shrinkage): rare, usually linked to artery injury.
• No improvement in sperm parameters: not a complication in the surgical sense, but a possible outcome. Not every man sees a meaningful improvement, even after a technically successful procedure.

Embolization-specific risks

Embolization carries risks of contrast dye reaction, radiation exposure, coil migration, and pain during the procedure as the vein is occluded. Serious complications are uncommon.

Anaesthesia risks

General and regional anaesthesia carry their own small risks, which your anaesthetist will review with you. These are generally low in otherwise healthy adults.

Life After Varicocele Surgery

For most men, life returns to normal within a few weeks. The longer-term experience depends on why you had the surgery.

If the goal was pain relief

Many men report significant improvement in scrotal pain after varicocele repair. Some report complete relief, and a smaller number report partial or no improvement. Pain that does not improve, or new pain, should be reviewed by your surgeon to look for hydrocele formation, recurrence, or other causes.

If the goal was improving fertility

Studies and current guideline summaries describe meaningful improvements in semen parameters in a substantial proportion of carefully selected men, with improvements appearing over 3–6 months and sometimes continuing for up to a year. Pregnancy rates — both natural and through assisted reproduction — improve in many couples after varicocele repair, although surgery does not guarantee pregnancy. Some men with very poor sperm production before surgery (including some with no sperm in the ejaculate) may produce sperm afterwards that allows IVF with ICSI, even if natural conception remains unlikely.

If pregnancy has not occurred after a reasonable waiting period (often 6–12 months, shorter if the woman is older), the next steps are discussed with the fertility team. These may include IUI, IVF, or IVF with ICSI, depending on the updated semen analysis and other factors.

If the goal was protecting testicular growth in adolescence

Adolescents who undergo surgery for a varicocele with testicular size discrepancy are followed with periodic examinations and ultrasound to confirm “catch-up” growth of the affected testicle.

Hormonal effects

Some men experience modest improvements in testosterone after surgery, particularly those who had low baseline levels. Hormone changes are usually checked at follow-up.

Recurrence and second procedures

A small proportion of men have a varicocele that returns or persists. If symptoms or fertility concerns return, a second procedure — often using a different approach, such as embolization after open surgery, or microsurgery after a non-microsurgical first attempt — can be considered.

Emotional and Relational Considerations

Male-factor infertility is often invisible and frequently goes unspoken. Being told that something about your body is part of the reason for a couple’s difficulty conceiving can affect self-esteem, masculinity, and the relationship. These feelings are common and valid.

A few things often help:

• Talking openly with your partner about expectations and timelines
• Remembering that varicocele is a physical condition, not a reflection of strength, fitness, or sexual function — sexual function is usually unaffected by both the varicocele and the surgery
• Setting realistic expectations: surgery aims to improve fertility potential, not to guarantee pregnancy, and improvements take months
• Seeking professional support — counselling, psychological support, or fertility support groups — if the emotional load is heavy

Varicocele in Adolescents

Varicoceles are sometimes found during routine medical examinations in teenagers or noticed by the boy or his parents. The considerations are different from those for adult men, because fertility cannot be directly tested (semen analysis is generally not performed in young adolescents) and the focus is on protecting future reproductive and hormonal function.

When surgery is considered in adolescents

Current paediatric urology guidance describes surgery as an option to consider when:

• The testicle on the affected side is significantly smaller than the other side (typically a defined percentage difference confirmed on ultrasound)
• Testicular growth on the affected side is falling behind over time
• The varicocele is causing pain
• The varicocele is large (grade 3) and bilateral
• In older adolescents, abnormal semen parameters are documented (if semen analysis is appropriate and the young person consents)

Approach

Several surgical approaches are used in adolescents, including microsurgical, laparoscopic, and open techniques. Lymphatic-sparing techniques are particularly important in younger patients to reduce the risk of hydrocele formation. The choice depends on the centre’s expertise and the boy’s anatomy.

What parents often want to know

• Many adolescent varicoceles never cause problems and can be monitored rather than operated on
• Recovery in healthy teenagers is usually rapid, with return to school within a few days and to sports after a few weeks
• Long-term effects on fertility are not fully predictable in any individual boy, so follow-up into adulthood is important
• Sexual development, including puberty and future sexual function, is not adversely affected by appropriate varicocele repair

Frequently Asked Questions

Will varicocele surgery cure my infertility?

Surgery is not a cure in the sense of guaranteeing pregnancy. It addresses one contributing factor — the varicocele — and aims to improve sperm quality. Whether pregnancy follows depends on many factors, including how much sperm improves, your partner’s fertility, and how long you have been trying to conceive.

How soon after surgery can we try to conceive?

Sexual activity is usually resumed within 1–2 weeks. However, meaningful improvements in sperm parameters take 3–6 months because of the sperm production cycle. Many couples are advised to continue trying naturally while waiting for follow-up semen analyses, unless other fertility factors require earlier intervention.

Will the surgery affect my testosterone or sex drive?

When the testicular artery is preserved, surgery does not reduce testosterone. In some men with low baseline testosterone, levels actually improve modestly. Sex drive and erectile function are not typically affected by the surgery itself.

Which approach is the best?

Major guidelines describe microsurgical subinguinal or inguinal varicocelectomy as the approach with the most favourable balance of low recurrence and complications, particularly when fertility is the goal. However, the right approach in any individual case depends on the reason for surgery, anatomy, prior procedures, and the surgeon’s expertise. This is a decision to discuss with a urologist or andrologist trained in the relevant techniques.

What if my varicocele comes back?

Recurrence is uncommon with microsurgical techniques but possible. Persistent or recurrent varicoceles can be treated again, often with a different approach. Embolization is frequently used after surgical recurrence, and microsurgery may be used after embolization or non-microsurgical surgery.

Can a varicocele come back on the other side?

A varicocele can develop on the previously unaffected side over time. Periodic examination can detect this.

Is surgery painful?

Most men describe the discomfort as mild to moderate and well controlled with standard pain medication. Strong post-operative pain is uncommon.

How do I choose a surgeon?

Look for a urologist or andrologist with specific training and experience in microsurgical varicocelectomy if fertility is your main goal. It is reasonable to ask how many procedures they perform per year, what approach they use most often, and what their typical outcomes and complication rates are. Meeting more than one specialist before deciding is a sensible approach.

Can lifestyle changes alone fix a varicocele?

Lifestyle changes do not make a varicocele disappear, but they can improve overall sperm quality and reduce some of the contributing harms. They are usually recommended alongside, or instead of, surgery depending on the situation.

Conclusion

Varicocele surgery is one of the few treatments in male reproductive medicine that directly targets a treatable, structural cause of poor sperm quality and scrotal pain. For carefully selected men — those with a varicocele that can be felt on examination, abnormal semen parameters or significant symptoms, and a clear clinical reason to expect benefit — current guidelines from major urology and reproductive medicine societies describe it as an option worth considering, with microsurgical techniques generally producing the best balance of low recurrence and few complications.

For others, watchful waiting, conservative measures, embolization, or moving directly to assisted reproduction may be more appropriate. The right choice is the one that fits your reason for seeking treatment, your anatomy and test results, your partner’s situation, and your goals for the months and years ahead. With clear information, realistic expectations, and a specialist who is experienced in the approach you choose, varicocele surgery can be a thoughtful step in a longer fertility or reproductive health plan rather than a single answer to a complex question.
