varicocele

A varicocele may cause poor development of a testicle, low sperm production or other problems that may lead to infertility. Surgery to treat varicocele may be recommended to address these complications. They may cause some discomfort or pain, but they often result in no symptoms or complications.

What Is an Varicocele?

A varicocele (VAR-ih-koe-seel) is an enlargement of the veins within the loose bag of skin that holds the testicles (scrotum). These veins transport oxygen-depleted blood from the testicles. A varicocele occurs when blood pools in the veins rather than circulating efficiently out of the scrotum.

A varicocele may cause poor development of a testicle, low sperm production or other problems that may lead to infertility. Surgery to treat varicocele may be recommended to address these complications.

Symptoms

A varicocele usually occurs on the left side of the scrotum and often produces no signs or symptoms. Possible signs and symptoms may include:

  • Pain. A dull, aching pain or discomfort is more likely when standing or late in the day. Lying down often relieves pain.
  • A mass in the scrotum. If a varicocele is large enough, a mass like a “bag of worms” may be visible above the testicle. A smaller varicocele may be too small to see but noticeable by touch.
  • Differently sized testicles. The affected testicle may be noticeably smaller than the other testicle.
  • Infertility. A varicocele may lead to difficulty fathering a child, but not all varicoceles cause infertility.

CAUSES

The testicles receive oxygen-rich blood from two testicular arteries — one artery for each side of the scrotum. Similarly, there are also two testicular veins that transport oxygen-depleted blood back toward the heart. Within each side of the scrotum, a network of small veins (pampiniform plexus) transport the oxygen-depleted blood from the testicle to the main testicular vein. A varicocele is the enlargement of the pampiniform plexus.

Risk factors

There don’t appear to be any significant risk factors for developing a varicocele.

Complications

Having a varicocele can make it difficult for your body to regulate the temperature of the testicles. Oxidative stress and the buildup of toxins can result. These factors may contribute to the following complications:

  • Poor testicular health. For boys going through puberty, a varicocele may inhibit testicle growth, hormone production, and other factors related to the health and function of the testicle. For men, a varicocele may result in gradual shrinkage due to tissue loss.
  • Infertility. A varicocele doesn’t necessarily cause infertility. An estimated 10% to 20% of men diagnosed with a varicocele experience difficulty fathering a child. Among men with fertility problems, about 40% have a varicocele.
