Yes, Varicocele can cause infertility. Having a natural conception is a blessing. The amount of happiness it brings to us. But infertility being a stop to the joy will be devastating and especially because of Varicoceles. Being an infertile couple can become a challenge in our life. Effects of fertility problems can have a major impact because of Varicocele and indirectly the female partner.
Varicoceles are the most common identifiable cause of male infertility. They are characterized by enlarged veins inside the scrotum, which can interfere with sperm health and fertility. These abnormal flow of blood causes creates testicular damage. Varicocele veins are swollen veins that are connected from the testicles to the testicular artery. Some of the issues caused by Varicose veins are sperm function, sperm motility, sperm concentration, and overall sperm quality are critical aspects evaluated through a semen analysis.
How Varicoceles Cause Infertility?
1. Increased Scrotal Temperature
The varicocele are dilated and fail to properly drain blood. This can increase the temperature in the testes, disrupting the optimal temperature of 2–4°C below body temperature that is required for sperm production and quality. This reduces both the quantity and quality of sperm.
2. Oxidative Stress
A varicocele may cause increased oxidative stress due to impaired blood flow. This results in the accumulation of reactive oxygen species (ROS), which can damage sperm DNA, reduce sperm motility, and lower sperm viability.
3. Hormonal Imbalances
A varicocele causing hormonal imbalance that can alter the hypothalamic-pituitary-gonadal (HPG) axis, leading to lower testosterone levels, which are essential for healthy sperm production.
Increased levels of testicular stress can also elevate certain hormones, like follicle-stimulating hormone (FSH), indicating impaired spermatogenesis.
4. Testicular Damage
Over time, varicoceles can lead to testicular atrophy like shrinking of the testes and structural damage, further reducing fertility potential.
5. Antisperm Antibodies
Antisperm antibodies (ASAs) are immune system proteins that mistakenly identify sperm as harmful invaders and attempt to attack or neutralize them. They just float around in the bloodstream, while others can attach to the sperm itself. Varicoceles increase the possibility of the immune system producing antigen antibodies, which can impair sperm function.
Detecting and Diagnosing Varicoceles
- There will be aching pain, mostly on the left side of the scrotum.
- There will be a testicular size difference which will be visibly seen.
- In few cases, ultrasound may detect varicoceles when physical exam is difficult due to the patient’s anatomy, or when other findings lead a physician to order a scrotal ultrasound.
- Large varicoceles can often be seen with the naked eye, or a patient can feel something resembling a worm like structure in their scrotum.
Varicocele Repair
Many men with varicoceles can have normal fertility. It is not necessary that every man can become infertile. However, in some cases, treating a varicocele e.g., through surgery like varicocelectomy and if preferring for a non surgical treatment like embolization can improve sperm quality and fertility outcomes.
Repairing varicocele can enhance semen quality significantly increase their chances of achieving spontaneous pregnancies. Some the treatment to restore fertility problems:
Microsurgical Varicocelectomy
Procedure
The procedure is done using a high powered operating microscope.
With a small incision is made in the groin or lower abdomen.
The affected veins are identified and tied off while preserving lymphatic vessels and arteries.
Advantages:
High success rate.
Low recurrence rate.
Minimal complications
Recovery Time: 1–2 weeks.
Laparoscopic Varicocelectomy
Procedure:
Performed using a camera and small instruments inserted through small abdominal incisions.
The dilated veins are tied off.
Advantages:
Minimally invasive.
Faster recovery than open surgery.
Open Surgery (Conventional Varicocelectomy)
Procedure: Performed via a larger incision.
Disadvantages: Higher recurrence and complication rates compared to modern techniques.
Alternative Non- Surgical treatment : Embolization for Varicocele repair
The varicocele embolization is a minimally invasive procedure where we bring back our normal fertility. It is done with a help of a Interventional Radiologist with a careful physical examination. Varicocele affects the blood flow mostly in the left testicular vein. It is a one-day procedure.
Procedure:
A small catheter is inserted through a vein in the groin.
A coil or a sclerosing agent (chemical) is used to block the dilated veins, stopping abnormal blood flow.
Advantages:
Outpatient procedure.
No incision or stitches.
Short recovery time (1–2 days).

Lifestyle Upgrades
Certain lifestyle factors can exacerbate the symptoms of a varicocele. Prolonged standing or sitting can cause the veins in the scrotum to become more swollen, leading to discomfort and pain. Wearing tight clothing or underwear can also put pressure on the veins and worsen symptoms.
A varicocele can be a source of stress and anxiety for men, particularly those who are trying to conceive. Lifestyle factors can play a significant role in the development and management of varicoceles.
For instance, smoking has been linked to an increased risk of varicoceles, as it can damage blood vessels and reduce blood flow to the testicles. Maintaining a healthy weight, exercising regularly, and managing stress can also help improve overall testicular function and reduce the risk of varicoceles.
Men with varicoceles can take proactive steps to manage their symptoms and improve their overall health. This includes making lifestyle changes such as quitting smoking, exercising regularly, and maintaining a healthy weight.
Reducing stress levels through relaxation techniques like meditation or deep breathing can also be beneficial. By adopting these healthy habits, men can enhance their testicular function and potentially alleviate some of the discomfort associated with varicoceles.
Does Varicocele Ligation Affect Testosterone Production?
- For most patients, testosterone levels do rise after repair.
- The association between varicoceles and male infertility has been known since the 1950s.
- The primary proposed hypotheses involve hyperthermia, venous pressure, testicular blood flow, hormonal imbalance, toxic substances, and reactive oxygen species.
Seeking Support for Infertile men with varicoceles:
Having even the smallest inconvenience that showing the symptom of varicocele, immediately have it checked with a expert.
Sometimes Varicoceles may not be visible to rectify. So fertility being the issue IVF are not the only solution. Varicocele can also be a problem for fertility. Have a thorough check with you doctors also considering non surgical procedures like embolization being a way of varicocele.
It’s essential for men with varicoceles to seek support from their healthcare provider, as well as from friends and family. Counseling or therapy can be beneficial in managing the emotional impact of a varicocele and infertility.
A varicocele can have a significant psychological impact on men, especially those who are trying to conceive. The diagnosis of a varicocele can be a source of stress and anxiety, particularly if it is associated with infertility. Men may feel a sense of shame or inadequacy and may worry about their ability to father children.
Infertility can also have a profound emotional impact on men, particularly if it is caused by a varicocele. Men may experience feelings of loss or grief and may struggle to come to terms with their diagnosis. The pressure to undergo treatment can also be a source of stress and anxiety.
Conclusion
It is also important to note the emerging evidence that lifestyle and genetic factors play a role in predicting which patients will manifest a clinical phenotype as a result of a varicocele and who will benefit from surgical repair. While many men with varicoceles may not experience symptoms, it is important to understand how a varicocele affects fertility and the potential benefits of treatment. There is evidence that many factors are responsible for the pathology of varicoceles’ apparent deleterious effect in clinical practice.
