What is a Varicocele?

Varicoceles, or swollen veins in the scrotum, are a common yet generally ignored illness that can have a significant influence on male reproductive health. These unusual veins can cause discomfort and impair testicular function, possibly leading to varicocele male infertility. Understanding varicoceles, their impact, and potential treatment options is critical for men looking to resolve fertility concerns and varicocele male infertility.

Can Varicoceles Cause Infertility?

Yes, varicoceles can result in infertility in some males. Varicocele are bulging veins in the scrotum that can impair sperm production and quality in the following ways: 

  • Varicoceles are the most commonly diagnosed cause of male infertility.
  • They can reduce sperm production and testosterone levels.
  • Varicoceles can also result in azoospermia, which occurs when there is no sperm present in the ejaculate.
  • Varicoceles can raise the temperature in the scrotum, which can impair sperm production.
  • Varicoceles are mostly asymptomatic, however, they may cause pain or discomfort, particularly while standing or exercising.  

Common Symptoms of Varicocele

Symptoms of a varicocele may include:

Pain: A dull soreness or discomfort in the scrotum or testicle, often after standing or exercising.

Swelling: A sensation of heaviness or tugging in the scrotum, or swelling in the testicles.

Mass: A scrotal mass that feels like a “bag of worms”

Size Difference: One testicle could be smaller than the other.

Infertility: Varicoceles can cause sperm production difficulties, leading to infertility.

Causes and Risk Factors of Varicocele

Varicoceles occur due to faulty valves in the scrotum’s veins, which allow blood to pool and enlarge them. Other causes include:

Valves: The scrotal valves that regulate blood flow may not be functioning properly.

Gravity: The left side of the body may experience a higher pull from gravity, causing blood to pool in the scrotum.

Hormonal Changes: Hormonal changes during puberty can lead to varicoceles.

Genetics:  Varicoceles may occur due to genetic factors.

Risk Factors

The risk factors associated with the cause of varicoceles include:

Physical Exercise: A lack of physical activity might contribute to varicoceles.

Tumors: Tumors can lead to varicoceles.

Kidney Disease: Kidney disease can lead to varicoceles.

Injuries: Injuries that impede blood flow in the scrotum can lead to varicoceles. 

How is Varicocele Diagnosed?

A varicocele is diagnosed using a physical exam, a medical history review, and, in some cases, imaging testing.

Physical Exam

  • A urologist examines the patient’s scrotum while they are standing.
  • A patient may feel a “bag of worms” in their scrotum.
  • A patient may experience pain that intensifies when standing or exercising and decreases after resting down.

Imaging Tests

  • Ultrasound is a technique that uses high-frequency sound waves to create images of the testicles’ veins.
  • Doppler ultrasonography detects the sound of blood moving backward through a valve.
  • Thermography uses infrared technology to detect heat in pooled blood.

Other Testing

  • Hormone levels, such as testosterone and follicle-stimulating hormone (FSH), can be checked through blood tests.
  • Semen analysis assesses sperm health and fertility.

Treatment Options for Varicocele

Varicoceles can be treated with both surgical and nonsurgical methods. The severity of the varicocele determines the appropriate treatment option. 

Surgical Procedures:

Varicocele treatments in surgery may include the following options:

Microscopic Varicocelectomy: A surgeon creates a small incision in the groin and uses a microscope to locate and tie off small veins.

Laparoscopic Varicocelectomy: A surgeon uses a video camera and surgical equipment to find and tie up veins in the lower part of the abdomen via minor incisions.

Non-Surgical Procedures:

Varicocele treatment without surgery may include the following options:

Catheter-Directed Embolization: An interventional radiologist utilizes imaging to guide a catheter into the body and stop blood flow in a vein.

Sclerotherapy: It involves injecting a sclerosing substance into a vein in order to block blood flow.  

Other Treatment Options:

Other varicocele treatments may include the following options:

Ice Packs: Can be beneficial for less severe varicoceles.

Over-the-Counter Medication: Pain medications such as ibuprofen or naproxen, can aid with discomfort.

Kegel Exercises: These are pelvic exercises that help increase blood flow and muscle tone.

The treatment results include pain reduction, an improved quality of semen, a better pregnancy rate, and hypogonadism.  

Impact of Varicocele on Fertility Outcomes

A varicocele, which is an enlarged vein in the scrotum, can have a significant impact on male fertility by reducing sperm count, motility, and sperm DNA damage, potentially leading to lower pregnancy rates in couples where the male partner has a varicocele; however, not all men with varicoceles experience fertility issues, and the severity of the impact varies depending on the individual case. Some key facts concerning varicocele and fertility include:

Associated with Infertility: According to studies, there is a clear link between varicoceles and male infertility, with a higher prevalence of varicoceles identified in men who are suffering fertility problems than in fertile men.

Mechanism of Impact: The swollen veins in a varicocele can raise testicular temperature, impairing sperm production and lowering sperm quality. 

Semen Analysis Changes: Men with varicoceles frequently have abnormal semen variables such as a lower sperm count, decreased motility, and increased abnormal sperm morphology.

Sperm DNA Damage: Varicoceles are associated with increased amounts of sperm DNA fragmentation, which can impair embryo development and pregnancy outcomes. 

Male Infertility and Varicocele: Myths vs. Facts

Male infertility is a sensitive topic that is sometimes cloaked in ignorance and misunderstanding. Varicocele is one such misunderstood illness, affecting a large proportion of males globally. Let’s discuss certain myths surrounding this condition and state the correct facts:

Myth 1: Varicocele is a rare condition. 

Fact 1: Varicocele is quite common.

Myth 2: Varicoceles always cause pain. 

Fact 2: Varicoceles are usually asymptomatic.

Myth 3: Varicoceles do not cause infertility.

Fact 3: Varicoceles can affect male fertility.

Myth 4: Surgery is the only treatment for varicocele.

Fact 4: Treatment options for varicocele are many.

Myth 5: Varicocele surgery always enhances fertility.

Fact 5: The effect of varicocele surgery on fertility varies.

Key Takeaways

While a varicocele can affect fertility, many men with varicoceles are able to conceive naturally. The severity of the varicocele (rated according to size and visibility) can influence the degree of impact on fertility, with larger, more visible varicoceles potentially causing more disruption. Before deciding on varicocelectomy, a complete review of the male partner’s reproductive situation, including semen tests, is required to establish whether treatment is suitable.  

FAQs on Varicocele

How Can Varicocele Be Treated Without Surgery?

Varicoceles can be treated without surgery by a process known as catheter-directed embolization, or embolization. It is a minimally invasive procedure carried out by an interventional radiologist.

Can Varicocele Be Cured Without Surgery?

Yes, varicoceles can be treated without surgery by a non-surgical method known as catheter-directed embolization. This method is less intrusive and requires a shorter recovery period than surgery.

What Causes Varicocele?

A varicocele is caused by faulty valves in the scrotum’s veins that restrict blood flow. This causes blood to accumulate and veins to expand. 

Can Varicocele Be Reversed?

Yes, varicoceles can be rectified using a variety of methods, including surgery and non-surgical procedures.

What Is the Cost of Varicocele Surgery?

Varicocele surgery in India can cost between ₹35,000 and ₹1,00,000, depending on the type of operation, patient condition, and surgeon’s experience.
