Male Infertility Treatment at Yaal Fertility Centre, Chennai

Male infertility is a symptom, not a diagnosis. The purpose of the evaluation is to find out why — because the cause determines whether the answer is a tablet, an operation, a change in habit, or ICSI.

Sperm production problems are the largest group. The testicles may produce too few sperm (oligozoospermia), sperm that swim poorly (asthenozoospermia), or sperm of abnormal shape (teratozoospermia). Often these occur together. In severe cases there may be no sperm in the ejaculate at all (azoospermia).

Varicocele — enlarged veins within the scrotum, somewhat like varicose veins — is one of the most common identifiable and correctable causes. It is thought to raise testicular temperature and impair sperm production, and it can often be surgically corrected.

Blockages in the tubes that carry sperm can prevent it reaching the ejaculate even when production is entirely normal. Causes include previous infection, injury, surgery, vasectomy, or a congenital absence of the vas deferens.

Hormonal causes — problems with testosterone, FSH, LH, prolactin, or thyroid function — can suppress sperm production and are among the more treatable causes, since they may respond to medication.

Genetic causes, including chromosomal abnormalities and Y-chromosome microdeletions, are found in a proportion of men with very low counts or azoospermia. Identifying them matters, both for treatment and because some can be passed to a son.

Lifestyle and environmental factors — smoking, heavy alcohol use, obesity, anabolic steroid use, heat exposure, and certain medications — can all suppress sperm quality. Some of these are reversible, which makes them among the most valuable to identify.

Ejaculatory disorders and, in some men, prior infection also feature. And in roughly a quarter of cases, no cause is found at all despite thorough investigation.

The male evaluation is quicker, cheaper, and far less invasive than the female one — which is exactly why it should happen early rather than after months of investigating the woman.

Semen analysis is the foundation. A sample is examined for the number of sperm, what proportion are moving and how well (motility), what proportion are normally shaped (morphology), the volume of the sample, and several other measures. It is typically repeated, because sperm counts fluctuate naturally and a single poor result is not a diagnosis. Illness, fever, or a short abstinence period can all skew one sample.

Hormone testing — a blood profile including testosterone, FSH, LH, prolactin, and thyroid function — helps distinguish a production problem from a blockage, and identifies hormonal causes that may respond to medication.

Scrotal ultrasound examines the testicles and surrounding structures, and is the standard way to identify a varicocele or a structural abnormality.

Genetic testing is indicated where the sperm count is very low or absent, to look for chromosomal abnormalities or Y-chromosome microdeletions. This is not routine for every man — it is targeted at severe cases, where it changes both the treatment plan and the counselling a couple should receive.

The results of these tests together determine what happens next. A hormonal cause may be treated medically. A varicocele may be corrected surgically. A blockage may be bypassed by retrieving sperm directly. Severe production failure usually points to ICSI.

Treatment follows the cause, and ranges from the entirely non-medical to advanced laboratory work.

Lifestyle changes come first where relevant, and are the most underrated intervention in male fertility. Stopping smoking, reducing alcohol, losing excess weight, stopping anabolic steroids, and avoiding prolonged heat exposure can all improve sperm parameters. The catch is time: sperm take around three months to develop, so changes made today show up in a semen analysis roughly three months later, not next week.

Medication can treat hormonal imbalances and infections, and may improve sperm production where a specific hormonal cause has been identified.

Surgery is used to correct a varicocele (varicocelectomy), to repair or bypass a blockage, or to reverse a vasectomy. Where a varicocele is corrected, improvement in sperm parameters typically takes three to six months to appear — again, because of the three-month sperm production cycle.

Surgical sperm retrieval — TESA, MESA, or micro-TESE — obtains sperm directly from the testicle or epididymis when none is present in the ejaculate. Sperm obtained this way are few and immature and cannot fertilise an egg unaided, which is why they are always paired with ICSI.

ICSI is the single most powerful tool available for severe male factor infertility. Because a single sperm is injected directly into each egg, it requires only one viable sperm per egg — which is why it works even where sperm are extremely scarce or surgically retrieved. Our success rate with ICSI in severe male factor cases is 50%, and 40% where sperm must be surgically retrieved in azoospermia.

The general principle is to treat the cause where it can be treated, and to use assisted reproduction where it cannot. Rushing an otherwise treatable man into IVF is as much a failure as leaving a severe case untreated.

Sometimes, genuinely — and this is worth taking seriously before assuming that assisted reproduction is the only path.

Sperm are produced continuously, and the full production cycle takes about three months. That single fact is the most useful thing to understand about male fertility: it means the sperm in a sample today reflects your health and habits of roughly three months ago, and it means changes you make now will show up in a repeat analysis about three months from now. It also means there is no overnight fix, and anyone selling one is not being honest with you.

The changes most consistently associated with better sperm parameters are:

• Stopping smoking — associated with lower count, motility, and morphology.
• Reducing alcohol, particularly heavy use.
• Losing excess weight — obesity affects hormone balance and sperm production.
• Stopping anabolic steroids — these suppress the body’s own sperm production, sometimes profoundly, and this is frequently not known by the men taking them.
• Avoiding excess heat — prolonged hot baths, saunas, and laptops resting directly on the lap.
• Reviewing medications with a doctor, as some prescription drugs affect sperm production.
• Managing chronic conditions such as diabetes and thyroid disorders.

These will not overcome a genetic cause, a complete blockage, or severe production failure. They can meaningfully improve borderline parameters, and in a couple where the male factor is mild, that improvement is sometimes the difference between needing IVF and not.

It should be said plainly, because it goes unsaid too often: a diagnosis of male infertility is a medical finding about sperm. It is not a judgement of masculinity, virility, or worth, and it has nothing to do with sexual function or performance. Men with entirely normal sexual function can have severe sperm abnormalities, and men with very low counts can have completely normal libido and potency.

The reason this matters clinically, and not just emotionally, is that shame delays diagnosis. Men frequently resist testing, or postpone it, or allow their partner to be investigated first and repeatedly — and in the meantime months pass, and if the female partner is in her late thirties, those months carry a real cost in egg quality that cannot be recovered.

A semen analysis is a simple test. It carries no risk, takes little time, and either rules out half of the possible causes or points directly at the answer. Both partners should be evaluated at the same time, from the beginning.

And a finding of male factor infertility is very often followed by a successful pregnancy — through treatment of the cause, through ICSI, or through surgical retrieval when there appears to be no sperm at all. Our success rates on this page reflect that: even in the most severe category, with sperm surgically retrieved in azoospermia, 40% of cases succeed.
