For many people, music serves as a soundtrack to particular moments in life. For one woman navigating years of fertility treatment, a single song became something far more significant: a source of comfort, motivation and emotional strength during one of the most challenging periods she would ever face.

The track was Titanium, the globally successful dance anthem performed by Australian singer-songwriter Sia and produced by French DJ David Guetta. Released in 2011, the song’s message of endurance and defiance resonated with millions of listeners worldwide. For one prospective mother undergoing repeated rounds of fertility treatment, however, its meaning became deeply personal.

The years spent pursuing pregnancy through in vitro fertilisation (IVF) were marked by a relentless cycle of appointments, tests and uncertainty. Medical consultations became routine. Blood tests, hormone monitoring and scans punctuated daily life, while every outcome carried the potential for either hope or disappointment.

During that period, Titanium evolved from a popular radio hit into a ritual. Before appointments and after difficult consultations, the song became a familiar companion. Its soaring chorus and themes of perseverance offered a brief but powerful sense of control amid circumstances largely dictated by medical procedures and biological uncertainty.

Listening to the song became a habit. Each time it played, it delivered the same emotional effect: a temporary surge of confidence and determination. The volume would rise, car windows would come down and the lyrics would be sung loudly, regardless of vocal ability. The experience provided a release from the anxiety and vulnerability that often accompany fertility treatment.

The emotional attachment deepened as the IVF journey progressed. In May 2012, when she and her husband travelled to the clinic for another embryo transfer, the song accompanied them. It was there again during the drive home from scans confirming the pregnancy was progressing successfully.

As the pregnancy advanced through the critical early milestones, the track became associated not only with the struggle to conceive but also with the possibility that years of effort might finally produce the outcome they had hoped for.

Pregnancy after fertility treatment can bring its own set of anxieties. Each medical appointment can feel like a test, and many prospective parents remain cautious even as positive milestones accumulate. Throughout those months, the song continued to provide reassurance and emotional reinforcement.

The long-awaited breakthrough came in January 2013 with the birth of the couple’s first son.

The family’s story did not end there. Fifteen months later, a second son was born following another IVF procedure using the couple’s remaining fertilised embryos. Four years after that, a third son arrived without fertility treatment.

The outcome represented a remarkable change from the uncertainty that had defined earlier years. Yet the family remains conscious that fertility treatment does not produce the same result for everyone who undertakes it.

Globally, IVF has enabled millions of births since its introduction, but success rates vary considerably depending on factors including age, medical history and individual circumstances. For many families, treatment involves repeated cycles, substantial emotional strain and, in some cases, heartbreaking disappointment.

That reality has shaped the way the woman views her own experience. She describes her family as extraordinarily fortunate and remains aware that others facing similar challenges may not receive the same outcome despite investing equal effort, hope and resilience.

More than a decade after the birth of her first child, Titanium continues to occupy a unique place in family life.

The song has become widely recognised within the household as her personal anthem. Unlike most of the music she listens to, it remains one of the few mainstream dance tracks that has retained a permanent place on her playlists. Its significance is no longer connected solely to fertility treatment but to a broader story of overcoming adversity.

Her children have grown up understanding its importance. Whenever the song appears on television or streaming services, they call her into the room. The track has become shorthand for a chapter of family history that predates many of their own memories but helped shape the family they know today.

Its symbolic role extends beyond the home. When she prepared a playlist to mark her 15th wedding anniversary, Titanium was chosen to represent 2011, the year when the fertility journey intensified and the song first became part of daily life. More recently, her husband sent her a voice message from a bar after hearing it playing in the background, immediately recognising the connection it still holds.

The experience reflects a broader truth about fertility treatment and prolonged medical struggles. Such journeys often become all-consuming, narrowing a person’s focus until nearly every decision, thought and emotion is filtered through the desire to achieve a successful pregnancy.

For those fortunate enough to reach that goal, life eventually expands beyond the treatment cycle. New priorities emerge, and the medical appointments that once dominated everyday existence begin to fade into memory.

Yet certain reminders remain.

For this mother, Titanium endures as a reminder not only of what she endured but of the determination required to navigate years of uncertainty. The fertility treatment ended long ago, but the emotions attached to the song never disappeared.

Today, when life presents new challenges and a moment of strength is required, the ritual remains largely unchanged. Alone in the car, she lowers the window, turns up the volume and lets the familiar chorus fill the space once again.

What began as a chart-topping pop song has become a permanent marker of resilience, carrying the memory of a struggle overcome and a family ultimately formed against long odds.
