Welcome back to Ask the Doc, an educational series from United Vein & Vascular Centers designed to provide clear, physician-led answers to common questions about vein and vascular health. Each week, a UVVC vein specialist explains everyday symptoms and what they may mean medically.
Varicoceles are enlarged veins within the scrotum that can cause discomfort, heaviness, and fertility concerns in some men. While some people experience mild symptoms, others may notice persistent pain or changes that affect daily comfort and reproductive health. In this Ask the Doc feature, Dr. William Kiang explains how varicoceles develop, common symptoms to watch for, and when treatment may be recommended.
“Could a varicocele be causing my pain or fertility problems?”
Q: What is a varicocele?
Dr. Kiang:
A varicocele is an enlargement of the veins inside the scrotum, similar to varicose veins that develop in the legs. It occurs when the valves inside these veins do not function properly, allowing blood to pool and increase pressure within the veins.
Varicoceles are fairly common and may develop gradually over time. Some people experience no symptoms, while others notice discomfort or fertility-related concerns.
Q: What are common symptoms of varicocele?
Dr. Kiang:
Symptoms can vary depending on the size of the varicocele and how much pressure has developed within the veins. Common symptoms may include:
- A dull aching or heavy sensation in the scrotum
- Discomfort that worsens after standing for long periods
- Pain that improves when lying down
- Visible or enlarged veins
- A feeling of heaviness or pressure
Some individuals may also notice that symptoms worsen throughout the day or after physical activity.

Concerned About Varicocele Pain or Fertility Issues?
Minimally invasive treatment options may help relieve discomfort and improve circulation. Schedule a quick and painless screening today.
Q: Does a varicocele affect fertility?
Dr. Kiang:
Varicoceles can affect fertility by increasing temperature and pressure around the testicles, which may interfere with sperm production and function.
Not everyone experiences male infertility, but varicoceles are one of the more common correctable causes. A screening can help determine whether the condition may be contributing to fertility concerns.
Q: When should someone seek medical evaluation for varicocele?
Dr. Kiang:
You should consider medical evaluation if you experience:
- Persistent testicular pain or discomfort
- A feeling of heaviness in the scrotum
- Scrotal swelling
- Enlarged or visible scrotal veins
- Fertility concerns
- Symptoms that worsen over time
A specialist can perform a physical examination and may recommend ultrasound imaging to evaluate blood flow and confirm whether a varicocele is present.
Q: What treatment options are available for varicoceles?
Dr. Kiang:
Treatment depends on the severity of symptoms and whether fertility is affected. In some cases, mild varicoceles may simply be monitored.
For symptomatic cases, treatment may focus on reducing abnormal blood flow and relieving pelvic vein dysfunction. Minimally invasive treatment is available at United Vein & Vascular Centers, such as varicocele embolization, and can often be performed in an outpatient setting and are designed to improve circulation while minimizing recovery time.
The goal of treatment is to relieve discomfort, improve vein function, and address fertility-related concerns when present.

What’s Next in the Ask the Doc Series
Circulation problems can affect more than just the legs, and conditions like varicoceles are an important example of how vein dysfunction can impact comfort and overall health. The Ask the Doc series continues to explore how vascular conditions present throughout the body and when symptoms may warrant evaluation.
In our next installment, Dr. Liza Thalheimer will address another common question patients ask: why does the skin on my lower legs look shiny or tight? She’ll explain how circulation problems can affect the appearance and texture of the skin, what these changes may indicate about vein health, and when medical evaluation may be recommended.
If you’re experiencing symptoms such as discomfort, heaviness, swelling, or other circulation-related concerns, schedule a consultation to explore your treatment options. A specialist can help determine the cause and recommend the most appropriate next steps.
