How Does a Varicocele Affect Male Fertility?
What Is a Varicocele?
It is similar to varicose veins in the leg. Valves inside the veins that drain the testicle don't work well, so blood pools and the veins swell. About 90% occur on the left side because of how the left vein drains.
How It Affects Fertility
- Heat: pooled warm blood raises the temperature around the testis, and sperm production works best slightly below body temperature
- Oxidative stress: can damage sperm DNA
- Effects on the testis: over time, the affected testis may become smaller
Symptoms and Grades
| Grade | Description |
|---|---|
| Grade 1 | Felt only when straining (Valsalva) |
| Grade 2 | Felt while standing, without straining |
| Grade 3 | Visible through the skin, often called a "bag of worms" |
Many varicoceles cause no symptoms. Some men notice a dull ache or heaviness that is worse after standing and better when lying down.
Diagnosis
- Physical exam by a urologist, standing and lying
- Scrotal Doppler ultrasound
- Semen analysis to check the effect on sperm
When Is Repair Recommended?
Doctors usually consider repair (microsurgery or embolisation) when a man has a palpable varicocele and abnormal semen analysis while trying to conceive, or has pain, or the testis is shrinking. Improvements in sperm are usually seen after 3 to 6 months.
Helpful Lifestyle Steps
- Supportive underwear for comfort
- Avoid prolonged standing and heavy lifting when uncomfortable
- Keep cool: no laptop on the lap, no hot baths
- Stop smoking, maintain a healthy weight
- Antioxidant-rich diet: fruit, vegetables, nuts
