Health experts are raising awareness about a surprisingly common condition called varicocele after doctors warned it could impact male fertility in some cases. Although many men may never realize they have the condition, specialists say understanding the symptoms and possible complications is important especially for couples struggling to conceive.
A varicocele occurs when veins inside the scrotum become enlarged, similar to varicose veins that appear in the legs. The condition usually develops slowly and most commonly affects the left side of the scrotum due to the way blood drains from the testicular veins. Medical experts estimate that around 15 percent of adult men have a varicocele, making it one of the most common male reproductive conditions worldwide.
Many Men Don’t Realize They Have It
One reason varicoceles often go undiagnosed is because they may cause few or no symptoms at all. Some men only discover the condition during fertility testing or routine medical exams. When symptoms do appear, they can include a dull ache in the testicles, swelling in the scrotum, or a heavy sensation that becomes worse after standing for long periods. Larger varicoceles may even feel like a “bag of worms” inside the scrotum due to the enlarged veins. Doctors also warn that some men may notice shrinking of the affected testicle, known medically as testicular atrophy.
How Varicoceles May Impact Fertility
Although many men with varicoceles remain fertile, specialists say the condition is one of the most common treatable causes of male infertility. Research suggests varicoceles are found in a large percentage of men experiencing fertility problems. Experts believe the enlarged veins may increase the temperature around the testicles, which can interfere with healthy sperm production. Higher temperatures may damage sperm quality, reduce sperm count, or affect sperm movement. Some doctors also believe poor blood flow and pressure changes inside the veins may contribute to hormone imbalances that affect testosterone levels and reproductive function. However, specialists emphasize that not every man with a varicocele will experience infertility. Many people with the condition are still able to father children naturally without treatment.
Online Discussions Reveal Mixed Experiences
Across online health communities, men frequently share concerns about whether varicoceles could harm their fertility in the future. Some Reddit users described struggling with declining sperm counts before eventually seeking surgery or embolization procedures. Others reported improvements after treatment. One Reddit user shared that sperm count and motility improved significantly several months after a minimally invasive embolization procedure, eventually leading to a successful pregnancy. Still, some patients say doctors remain cautious about recommending surgery immediately because treatment does not guarantee fertility improvements for every patient.
Treatment Options Depend on Symptoms
Doctors say treatment is not always necessary, especially if the varicocele causes no pain or fertility problems. In many cases, physicians simply monitor the condition over time. For men experiencing discomfort or infertility issues, treatment options may include surgery or a minimally invasive procedure called embolization. Both approaches aim to block the damaged veins and redirect blood flow through healthier veins. Microsurgical procedures are often considered the most effective treatment option with lower risks of complications.
When to See a Doctor
Health experts recommend seeing a doctor if someone notices swelling, pain, visible enlarged veins, or changes in the size or shape of the testicles. Men facing fertility difficulties may also benefit from medical evaluation and semen analysis testing. While varicoceles are usually not dangerous, doctors stress that early diagnosis can help identify whether treatment might improve symptoms or fertility outcomes. For many men, the condition can be successfully managed once properly diagnosed.
