Male Infertility: Causes, Symptoms, Tests & Treatment

When a couple struggles to conceive, attention often focuses first on the woman — but the reality is that male factors contribute to nearly half of all infertility cases. Male infertility is common, usually treatable, and nothing to be ashamed of. Yet many men delay getting checked, partly because the condition rarely causes obvious symptoms. At Pune IVF, we believe fertility is a shared journey, and evaluating both partners together gives couples the fastest path to answers. This guide explains the causes, symptoms, tests, and treatments for male infertility.

What is male infertility?

Male infertility refers to any health issue in a man that reduces the chances of his partner becoming pregnant. Most often, it comes down to a problem with sperm — too few sperm, sperm that don’t move well, or sperm of abnormal shape — or, in some cases, an absence of sperm altogether. The encouraging news is that even when there’s a significant sperm problem, modern fertility treatments mean fatherhood is very often still achievable.

Male infertility is more common than people think

It’s a common misconception that infertility is mainly a “female problem.” In fact, men and women contribute to fertility challenges in roughly equal measure — male factors are involved in about 40–50% of cases, either on their own or alongside female factors. This is exactly why testing the male partner early, with a simple semen analysis, is so important; it can save couples months of uncertainty.

Symptoms of male infertility

For most men, there are no obvious symptoms — the inability to conceive after a year of regular, unprotected intercourse is often the only sign. Sometimes, though, an underlying cause produces clues, such as:

• Problems with sexual function — low sex drive, or difficulty with erection or ejaculation
• Pain, swelling, or a lump in the testicle area
• Swollen veins in the scrotum (a varicocele)
• Reduced facial or body hair, or other signs of a hormonal imbalance
• Recurrent respiratory infections (in certain genetic conditions)

Because symptoms are usually absent, testing is the only reliable way to know.

What causes male infertility?

The causes fall into several groups. Sperm production and quality problems are the most common — including low sperm count (oligospermia), poor movement (low motility), abnormal shape (poor morphology), or no sperm at all (azoospermia). Other important causes include:

• Varicocele — enlarged veins in the scrotum, one of the most common and treatable causes
• Infections — including some STIs and inflammation of the testicles or epididymis
• Hormonal imbalances — problems with testosterone or the pituitary gland
• Genetic conditions — such as Klinefelter syndrome or Y-chromosome changes
• Blockages — preventing sperm from being ejaculated (including after vasectomy or hernia surgery)
• Lifestyle and environmental factors — smoking, excess alcohol, recreational drugs, anabolic steroids, obesity, stress, and heat exposure (hot tubs, tight clothing, laptops on the lap)
• Medical treatments — such as chemotherapy or radiation

Understanding sperm health: count, motility and morphology

A healthy sperm analysis looks at three key things. Count (or concentration) is considered low below about 15 million sperm per millilitre of semen. Motility measures how well sperm swim, and morphology assesses their shape. Often these occur in combination. Importantly, a low count doesn’t mean conception is impossible — it only takes one healthy sperm to fertilise an egg, and treatments exist for even the most severe cases.

How is male infertility diagnosed?

Diagnosis is straightforward and begins with a semen analysis — the single most important test, which examines sperm count, motility, shape, and semen volume. Depending on the results, our specialists may recommend hormone blood tests (testosterone, FSH, LH, prolactin), a scrotal ultrasound to check for varicoceles or blockages, genetic testing, and in some cases a small testicular biopsy. Crucially, even if a semen test shows very low or no sperm, treatment is often still possible.

Treatment options for male infertility

Treatment depends entirely on the cause, and ranges from simple to advanced:

• Lifestyle changes can meaningfully improve sperm health — stopping smoking and recreational drugs, moderating alcohol, maintaining a healthy weight, reducing heat exposure, managing stress, and eating a diet rich in antioxidants, zinc, and omega-3.
• Medical treatment addresses infections (with antibiotics) or corrects hormonal imbalances.
• Surgery can repair a varicocele or relieve a blockage.
• Surgical sperm retrieval — techniques such as TESA, PESA, and micro-TESE can recover sperm directly from the testicles even in cases of azoospermia.
• Assisted reproduction — IUI for mild cases, and IVF, but above all ICSI (Intracytoplasmic Sperm Injection), which has transformed male infertility treatment by injecting a single healthy sperm directly into an egg. Where no sperm can be retrieved, donor sperm is an option.

At Pune IVF, our in-house andrology lab and expertise in ICSI and surgical sperm retrieval mean even severe male infertility can often be successfully treated.

When should men see a fertility specialist?

A couple should seek evaluation after 12 months of trying without success — or after 6 months if the female partner is over 35. Both partners should ideally be assessed together. If you already know of a testicular injury, surgery, or other risk factor, it’s worth getting checked sooner. Early evaluation simply means more options.
