A varicocele is an enlargement of veins inside the scrotum. The skin-covered sac that holds the testicles or the scrotum contains the spermatic cord which houses a number of arteries and veins that maintains the blood flow to the reproductive glands. Abnormalities in those veins can cause the varicocele. This condition is very similar to the varicose veins on the legs. It is usually described as a "bag of worms".

Causes of Varicocele

Even today doctors are uncertain about the causes of varicocele. However, it is theoretically believed to be formed due to some defect in the valves of the veins. These valves control the blood flow to and from the testicles. If due to some reasons there is an obstruction in the blood flow, then the blood backs up causing the veins to swell and enlarge.

Usually, this problem occurs during puberty when the testicles grow rapidly and need maximum blood flow. Varicocele leads to poor circulation, thus increasing the blood flow and the raising the temperature of the testicles. In some cases, this can hamper the sperm production or damage the already produced sperm leading to infertility.
Also, varicocele is commonly seen on the left side of the testicles

When to Seek Treatment

There are certain varicoceles that can be left untreated as it does not cause any kind of harm or discomfort to the patient. However, if you experience pain or are not able to conceive due to low sperm count or motility, then your varicocele might need correction. If one finds the prevailing symptoms of this condition, it is always better to get it examined by an urologist as early as possible, who would help out with the best treatment option available.
