Varicocele
Mild
A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins in other parts of the body. It most commonly occurs on the left side and may cause no symptoms. Some people experience a dull aching discomfort, a feeling of heaviness, or a noticeable enlargement of the scrotal veins. Varicoceles can be associated with impaired testicular development or abnormal sperm production in some individuals and are sometimes discovered during evaluation for fertility problems.

When to Seek Medical Attention
Varicocele is usually not an emergency and may cause a dull scrotal ache or no symptoms. Seek medical assessment for persistent pain, testicular size changes, swelling, or concerns about fertility. Sudden severe testicular pain or rapid swelling requires emergency evaluation because other conditions, including testicular torsion, may have similar symptoms.

Overview
A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins in other parts of the body. It most commonly occurs on the left side and may cause no symptoms. Some people experience a dull aching discomfort, a feeling of heaviness, or a noticeable enlargement of the scrotal veins. Varicoceles can be associated with impaired testicular development or abnormal sperm production in some individuals and are sometimes discovered during evaluation for fertility problems.
Symptoms 2
Heavy Menstrual Bleeding
Irregular Periods
Causes 1
A varicocele develops when blood is not efficiently returned from the veins of the testicle, allowing the veins to enlarge. Abnormal or ineffective functioning of the valves within these veins can contribute to backward blood flow and venous enlargement. The left-sided predominance is related partly to differences in the anatomy of the testicular veins. The exact mechanisms responsible for fertility effects are not completely established, but increased scrotal temperature and altered blood flow may play a role.
High Cholesterol
Risk Factors
Varicocele is most often identified during adolescence or early adulthood. The condition is more common on the left side because of differences in venous anatomy. Family or individual anatomical factors may influence susceptibility. A varicocele may be associated with abnormal testicular growth or fertility difficulties, although many people with varicoceles have normal fertility and no symptoms. A newly appearing varicocele later in adulthood may require evaluation for an underlying cause.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
A varicocele is often detected during a physical examination while standing and sometimes while performing a maneuver that increases abdominal pressure. The clinician may assess the size of the testicles and the degree of venous enlargement. Scrotal ultrasound can confirm the diagnosis and evaluate blood flow when the examination is uncertain. Semen analysis may be considered in people being evaluated for fertility, and adolescents may undergo monitoring of testicular growth.
Prevention
Key Prevention Tips
There is no established way to completely prevent varicocele because its development is largely related to individual venous anatomy
Regular medical assessment during adolescence can help identify changes in testicular size or development
People who notice scrotal swelling, persistent discomfort, or fertility concerns should seek evaluation
Early assessment is particularly useful when a varicocele is associated with reduced testicular growth or abnormal reproductive function
Prevention Guidance
There is no established way to completely prevent varicocele because its development is largely related to individual venous anatomy. Regular medical assessment during adolescence can help identify changes in testicular size or development. People who notice scrotal swelling, persistent discomfort, or fertility concerns should seek evaluation. Early assessment is particularly useful when a varicocele is associated with reduced testicular growth or abnormal reproductive function.
