Overview
There is a conversation that happens in fertility clinics more often than most people realise.
A couple has been trying to conceive for over a year. They have done everything they were told. Tracked cycles. Timed intercourse. The woman has had her hormones checked, her ovaries scanned, her uterus evaluated. Everything comes back mostly fine.
And then someone finally asks, “Has he been tested?”
Sometimes the answer is no! Not because anyone was careless, but because male fertility rarely enters the conversation early enough. The assumption, often unspoken, is that if something is wrong, it is probably on her side.
That assumption is costing couples time, money and emotional energy they cannot get back.
The number that changes everything
Here is what the research consistently shows: “male factor infertility contributes to approximately 40 to 50% of all infertility cases. In roughly 30% of cases, it is the sole reason a couple is not conceiving”. (Source: ICMR)
That is not a small number. That is half the picture and it is regularly examined second, not first. What makes this more urgent in the Indian context is the scale of the problem at home.” A 2025 analysis of three decades of data found that India recorded the highest rise in male infertility prevalence among all South Asian countries, nearly 59% over 30 years, with men aged 25-29 being the most affected group. This is no longer a problem for older couples or rare cases. It is affecting men in the prime years of their lives”.

What actually causes male infertility?
Male infertility is not one condition. It is a collection of different problems that affect sperm production, sperm movement or sperm’s ability to fertilise an egg. Understanding which category applies changes everything about how treatment proceeds.
i) Low sperm count (Oligospermia)
This is the most commonly identified issue. A healthy semen analysis shows at least 15 million sperm per millilitre. When that number drops, the statistical odds of natural conception drop with it. But low count alone does not mean conception is impossible. It means it becomes less efficient.
ii) Poor sperm motility
Sperm count can be perfectly normal while motility, the ability to move forward effectively is compromised. Sperm that cannot swim efficiently cannot reach the egg regardless of how many there are. This is often discovered only during a detailed semen analysis, which many men never have.
iii) Abnormal sperm morphology
Shape matters. Sperm with structural abnormalities in the head, midpiece or tail struggle to penetrate and fertilise an egg. A certain percentage of abnormal forms is normal, but when it exceeds clinical thresholds, conception becomes harder.
iv) Sperm DNA fragmentation
This one is perhaps the most underdiagnosed. A semen analysis can look completely normal: count, motility and morphology all within range, while the genetic material inside the sperm is fragmented. High DNA fragmentation leads to fertilisation failure, poor embryo quality and recurrent miscarriage. It requires a specific test that is not part of a standard semen analysis.
v) Hormonal imbalances
Testosterone, FSH, LH and prolactin all play roles in sperm production. When any of these are out of range, sperm production suffers. Hormonal causes are treatable, but only if they are identified.
vi) Varicocele
Enlarged veins in the scrotum raise testicular temperature, which impairs sperm production. Varicocele is present in roughly 15% of all men and in up to 40% of men being evaluated for infertility. It is also one of the most correctable causes , surgically or through other procedures , with meaningful improvement in sperm parameters afterwards.
vii) Lifestyle factors that are consistently underestimated
Heat exposure from laptops, saunas and hot baths. Smoking, which damages sperm DNA and reduces count. Alcohol, which disrupts testosterone production. Obesity, which raises oestrogen levels in men and suppresses sperm production. Chronic stress, which elevates cortisol and directly impacts sperm quality.
The encouraging part is that many of these lifestyle-driven causes are reversible, but only when you know what to address and how. If you want a practical starting point, this guide on best practices to protect sperm count in men breaks down exactly what daily habits move the needle and which ones silently work against you.
What treatment actually looks like?
The good news is that male infertility is often treatable. Let us explore the treatment options for male infertility, available at the best fertility hospital in Chennai:
i) Lifestyle modification
For men whose infertility is linked to weight, smoking, alcohol or heat exposure, targeted lifestyle changes can improve sperm parameters within three to six months. Sperm takes approximately 74 days to mature, which means changes made today show up in semen analysis results roughly three months later.
ii) Hormonal treatment
When a hormonal imbalance is identified, medication can often correct it. Clomiphene, FSH injections and other agents have been used effectively to stimulate sperm production in men with low counts linked to hormonal causes.
iii) Varicoceler repair
Surgical correction of varicocele has been shown to improve sperm count and motility in a significant percentage of men. For couples who have been trying without success, this intervention alone has changed outcomes.
iv) IUI – Intrauterine Insemination
When sperm count or motility is mildly reduced, IUI concentrates and prepares the best sperm and places them directly into the uterus at the time of ovulation. It removes some of the distance sperm has to travel and increases the odds meaningfully for the right candidates.
v) IVF with ICSI
When sperm parameters are more severely compromised, ICSI (Intracytoplasmic Sperm Injection) is one of the most effective tools available. A single healthy sperm is selected and injected directly into the egg. It bypasses most of the barriers that poor count, motility or morphology create.
vi) Surgical sperm retrieval
In cases where no sperm appear in ejaculation, a condition called azoospermia, sperm can often be retrieved directly from the testicular tissue through procedures like TESA or PESA. What once meant no biological option now has a viable path forward.
The conversation most couples are not having
Male fertility testing is non-invasive, relatively inexpensive and can be completed quickly. A semen analysis takes one appointment. Results are typically available within days.
Yet it is often the last thing evaluated. Sometimes after months or years of investigation and treatment focused entirely on the woman.
At a fertility hospital in Chennai that approaches infertility as a couple’s issue from the very first consultation, both partners are evaluated together. Because the data supports it and because time matters when you are trying to build a family.
What getting evaluated actually involves?
For men, a basic fertility evaluation typically includes a semen analysis, hormone blood tests and a physical examination. If the initial results raise questions, more specific tests like sperm DNA fragmentation analysis or a scrotal ultrasound may follow.
It is neither complicated nor painful. Indeed, it takes far less time than another six months of trying without answers.
But evaluation is only useful when it leads to the right specialist. Not every doctor who sees male patients is equipped to interpret these results in the context of a couple’s fertility journey.
If you are unsure what to look for, this is a practical read on how to choose the right male infertility doctor, covering the questions worth asking, the qualifications that matter and what a thorough evaluation should actually include.
A different way to think about this
Fertility has been framed as a woman’s domain for too long. The science does not support that framing. The outcomes certainly do not.
When both partners are evaluated early, treatment becomes more targeted, timelines get shortened and emotional energy is spent more wisely. And couples stop spending months addressing one half of the equation while the other half remains unexamined.
At ARCIVF, we evaluate both partners from day one. Because that is what the evidence supports and getting to the right answer faster is always better than getting there eventually.
The Bottom line
Male infertility is common and is often treatable. But it is regularly caught later than it should be.
If you and your partner have been trying to conceive without success, the most useful thing you can do right now is ensure that both of you have been properly evaluated, not just one.
The answer you have been looking for, might be closer than you think. It just requires asking a different question first!
