Male infertility is less talked about, but it is, of course, as important as female infertility. As per the leading Fertility Centre in Kolkata, male-related issues are responsible for approximately 40–50% of all infertility cases. The presence of varicocele in men is one of the contributing factors to male infertility. It is one of the big factors that can make it impossible for men to father their own children.

What is a Varicocele?

It is marked by an abnormal enlargement of the veins within the scrotum. Similar to varicose veins in the legs, a varicocele develops when the pampiniform plexus veins in the scrotum become unusually swollen. These veins drain blood from the testicles in men. Blood starts to pool when the valves in these veins fail to work properly, leading to poor circulation. It causes swelling of the veins and leads to a varicocele.

Varicoceles are more commonly found on the left side of the scrotum due to the way blood drains from the left testicle. Generally, varicoceles are unilateral, although they can affect one or both testicles.

How Does Varicocele Affect Male Fertility?

The exact connection between varicocele and infertility remains unclear to medical experts. However, sperm production and function can be negatively impaired due to these enlargements in various ways:

Higher Scrotal Temperature
The scrotum helps maintain the testes outside the body at a cooler temperature, which is essential for effective sperm production and survival. When warm blood accumulates around the testicles due to varicoceles, this cooling mechanism gets affected. It increases the scrotal temperature. Even if there is a minor increase in temperature, it can affect the sperm production process – also referred to as spermatogenesis. This is one of the reasons why infertility treatment in Kolkata often includes screening for varicocele in male patients.
Oxidative Stress
When there are varicoceles, there is higher oxidative stress. Due to this, the DNA in sperm cells gets damaged. It can lead to lower sperm motility, abnormal sperm structure, and reduced chances of successful fertilization, affecting the IVF success rate in some cases.
Hormonal Imbalance
According to infertility specialists in Kolkata, the levels of reproductive hormones like testosterone can be affected due to varicoceles. It can impact sperm production further. The overall fertility can get impaired when this happens.
Testicular Damage
Long-standing or severe varicoceles in men may lead to testicular atrophy, causing the testes to shrink. It can impair sperm production further and may increase the need for assisted methods like IVF or IUI. For many couples, understanding IVF cost in India Kolkata and IUI cost in Kolkata becomes important at this stage.

Is Varicocele a Common Cause of Male Infertility?

Yes. 15% of the male population is found to have this issue, although it can arise in as much as 40% of males with primary infertility and 80% of men with secondary infertility.

As you can clearly see, varicocele has a high prevalence. Naturally, it is among the main reasons for potentially reversible male infertility. Awareness and timely intervention from a qualifiedIVF doctor in Kolkatacan make a significant difference.

What are the Treatment Options for Varicocele-Related Infertility?

Treatment is not necessary for all varicoceles. It might be needed in case the varicocele is causing discomfort or aching, or is leading to testicular atrophy. Men can also go for treatment if varicocele is related to abnormal semen analysis. If it is suspected to be leading to unexplained infertility in a couple, treatment will be necessary.

The treatment options include:

Surgical Varicocelectomy
It is the most common treatment and includes tying off the affected veins, which can get the blood flow redirected into normal veins. Open surgery, laparoscopy, or microsurgery can be used to do this. Microsurgical varicocelectomy offers a high success rate with minimal complications, making it the preferred gold standard treatment. This option is often recommended by experienced infertility specialists in Kolkata.
Percutaneous Embolization
This is a less invasive procedure, where a catheter is inserted through a vein. A special solution or tiny coils can be used to seal off the affected veins effectively. Men opting for non-surgical methods should consider consulting clinics that offer a breakdown of IVF cost in Kolkata and alternative fertility treatments.
Observation and Lifestyle Changes
If varicoceles are mild and cause no fertility issues, these can be just observed. Lifestyle adjustments like managing oxidative stress through diet, avoiding excessive heat, etc., may be enough. However, it is best to keep in touch with a clinic that provides infertility treatment in Kolkata for regular assessments.
