Male infertility remains a topic rarely discussed, often overshadowed by social pressures and hesitation. Yet, it contributes to nearly half of all cases where couples struggle to conceive. Among the many causes, varicocele stands out as one of the most silent and underrecognised conditions, affecting a significant number of men in India. With male reproductive health still a taboo, countless men remain unaware of their condition for years. Fertility tests often reveal the issue only after prolonged delays, adding emotional stress for couples. We got in touch with Dr. Suparna Bhattacharya, Fertility Specialist, Nova IVF Fertility, Kolkata, who told us more about the same.What Is a Varicocele?A varicocele occurs when the veins in the scrotum become enlarged, similar to varicose veins in the legs. These weakened, dilated veins disrupt blood flow to the testicles, causing a gradual rise in temperature that negatively affects sperm production and quality. Most men experience no pain, which is why the condition is often undetected, earning it the label of a “silent” problem. In many cases, it is discovered only during routine infertility evaluations.Why It’s a Common Yet Ignored Cause of Male InfertilityVaricocele is particularly concerning because it often goes untreated, leading to more serious reproductive consequences. Dr. Suparna Bhattacharya said, “The condition may not produce noticeable symptoms—no pain, no swelling—yet internally, impaired blood flow and heat buildup gradually reduce sperm count, motility, and quality. Research shows varicocele accounts for a large proportion of male infertility cases, and the condition is largely reversible if identified early.”A lack of awareness, coupled with the common misconception that infertility is primarily a female issue, often delays evaluation of the male partner. Many men only undergo semen analysis or scrotal ultrasound after significant time has passed.Can Surgery Restore Fertility?The encouraging news is that varicocele is one of the few male infertility issues that can be effectively treated with surgery. Varicocelectomy, the most common procedure, involves tying off the affected veins while preserving normal blood flow. This helps cool the scrotum and allows sperm production to return to healthier levels.Dr. Suparna Bhattacharya told us that post-surgery, many men experience notable improvements in sperm count and motility within six months. For couples, this can mean natural conception without advanced fertility treatments. Correcting varicocele can also improve sperm DNA integrity, enhancing the success rates of procedures like IVF or ICSI.Potential Consequences of Untreated VaricoceleNot all varicoceles require surgery, especially if mild or asymptomatic. However, undetected or significant varicoceles can progressively impair sperm quality and, in some cases, lead to testicular atrophy. Delayed diagnosis can reduce the likelihood of natural conception as men age.When Should You See a Doctor?Men who have been trying to conceive for over a year should undergo a comprehensive fertility check-up. A simple semen analysis and physical examination are often sufficient to detect most varicoceles. “Early intervention is crucial, particularly for those hoping for natural conception or planning to start a family,” said Dr. Suparna BhattacharyaPromoting awareness about male reproductive health is just as important as educating women on fertility. Varicocele is a silent, yet easily treatable, condition. Timely diagnosis and treatment can restore fertility and reduce the emotional and financial strain on couples. The first step toward healthier, happier families is acknowledging the issue, seeking treatment, and discussing it openly.
