Diagnosed with zero sperm, he became a father twice—Here’s how science made it possible

Advances in assisted reproductive technologies are transforming outcomes for men with azoospermia, once considered irreversible infertility

For decades, a diagnosis of azoospermia, the complete absence of sperm in semen, was considered a biological dead end for men hoping to become fathers. In medical textbooks, it is often translated into a single, devastating conclusion that biological parenthood would be impossible.

But advances in reproductive medicine are quietly dismantling that assumption.

A recent case from Maharashtra underscores just how dramatically the fertility landscape has changed. A couple, married for nearly a decade, went on to conceive not once but twice, despite the male partner being diagnosed with severe azoospermia. Their journey is not just a personal victory, but a window into how assisted reproductive technologies are redefining male infertility in India.

Male infertility accounts for nearly 40–50 per cent of infertility cases globally, yet it remains far less discussed than female reproductive challenges. Azoospermia, affecting roughly 1 per cent of all men and up to 15 per cent of infertile men, is among the most severe forms.

In many cases, sperm production occurs inside the testes but does not reach the semen due to blockages or hormonal dysfunctions. For years, this distinction mattered little to patients because treatment options were limited.

Today, that gap between production and ejaculation is precisely where medical innovation steps in. Procedures such as Testicular Sperm Extraction (TESE) and Intracytoplasmic Sperm Injection (ICSI) have transformed the prognosis for men with severe infertility. TESE allows doctors to retrieve viable sperm directly from testicular tissue, while ICSI enables fertilisation using a single sperm injected into an egg under a microscope.

These techniques are no longer experimental. They are now routinely offered at advanced fertility centres across India, particularly in urban hubs, and success rates have steadily improved over the last decade.

In this case, viable sperm retrieved through TESE were used to fertilise eggs via ICSI. Multiple embryos were created and preserved through cryopreservation, allowing the couple to plan pregnancies years apart without repeating the entire treatment cycle.

One of the quiet revolutions in fertility care is embryo freezing. It reduces physical strain, lowers costs over time, and gives couples flexibility, especially women who may not wish to undergo repeated hormonal stimulation.

Clinicians tell THE WEEK that frozen embryo transfers today offer success rates comparable to, and in some cases better than, fresh transfers. "For couples facing emotionally and financially demanding fertility journeys, this can be the difference between one chance and several," says a leading gynaecologist and ART expert based in Mumbai.

Stories like these also highlight a deeper issue, that of the persistent stigma around male infertility. In India, infertility is still overwhelmingly framed as a 'women’s issue', even when medical evidence points elsewhere. Men often delay testing, and couples lose precious years before reaching appropriate care.

Public health experts argue that awareness is equally crucial, just as is technology. Early diagnosis, timely referral, and open conversations could significantly reduce the emotional toll of infertility.

What this case ultimately demonstrates is not a miracle, but momentum. With the right diagnosis, counselling, and access to advanced reproductive care, conditions once labelled irreversible are increasingly manageable. For couples navigating infertility, especially where male factors are involved, the message is clear that a diagnosis is no longer a full stop. Sometimes, it’s just the beginning of a longer, more hopeful sentence.
