Sometimes, one or more of the veins of the spermatic cord may become enlarged and develop an abnormality known as a varicocele.

These veins are known as the pampiniform plexus. A varicocele only develops in the spermatic cord, and nowhere else. It is similar to varicose veins found in the legs. It can cause several issues and may contribute to male factor infertility.

Causes & Symptoms

Varicocele is a medical condition that is characterized by the enlargement of veins within the spermatic cord, contained within the scrotum (the loose bag of skin that holds the testicles). Varicoceles are similar to the varicose veins found in the leg, and they can begin to form during puberty. They are usually found on the left side of the scrotum, but can also be present on both sides, though bilateral varicocele is much less common.

Varicocele may lead to male factor infertility because it can impair sperm production and decrease sperm quality and motility. Occasionally, varicoceles may cause pain or discomfort, though most varicoceles, particularly mild ones, do not interfere with fertility or cause discomfort. Aside from fertility, varicoceles can also interfere with the normal development of the testicles and even cause them to shrink (atrophy). Varicoceles can easily be diagnosed and most don’t require treatment. If the varicocele is associated with infertility and abnormal semen parameters, or produces symptoms, it is usually repaired surgically.

Medications & Supplements

Treatment usually involves surgical procedures and medications are not commonly prescribed. Because varicocele can lead to infertility, it is important to start the treatment early in order for your sperm production to improve.

Treatments & Surgery

In most cases, varicoceles do not require treatment. However, if associated with pain and discomfort, infertility and/or testicular atrophy, you may want to consider surgical repair.

Since this condition can lead to fertility issues or adversely affect proper testicular functioning, the earlier the patient begins the treatment, the higher the chances of enhancing sperm quality. In some cases, supportive underwear or jockstrap can decrease discomfort associated with varicocele.

Right-sided varicoceles, or bilateral varicoceles, are uncommon and should be evaluated as they may be associated with other abnormalities.
