When a GP delays or withholds an IVF referral: does NSW law recognise a claim for lost fertility?

That experience — of being told to wait, to be patient, to try naturally for a little longer — is not unusual. For many people, it is the whole story of how they lost the fertility window they did not know was closing. The question this article addresses is a precise one: when a GP delays or withholds a referral for specialist fertility assessment or IVF, and that delay causes measurable harm to a person’s reproductive capacity, does NSW law provide a remedy?

The answer requires understanding both what the clinical guidelines actually require of a GP in this situation, and what the law demands when those requirements are not met.

What fertility decline is, and what clinical management is supposed to look like

Female fertility declines with age. That is a biological fact. What is less well understood — and what the clinical guidelines address directly — is the rate of that decline, and the specific thresholds at which a GP is required to act rather than wait.

Ovarian reserve — the quantity and quality of eggs remaining — begins declining meaningfully in a woman’s early thirties and accelerates sharply after 35. Anti-Müllerian hormone (AMH) is the primary blood marker used to assess ovarian reserve. A low AMH result does not mean pregnancy is impossible, but it does mean the window for assisted reproduction is narrowing, and that every additional month of delay carries a real biological cost. For information on fertility and reproductive health in plain language, Healthdirect Australia provides a useful starting point.

According to the Australian Institute of Health and Welfare, approximately one in six couples in Australia experience difficulty conceiving.¹ The AIHW’s most recent data on assisted reproductive technology shows that in 2021, 22,533 women underwent 91,532 ART treatment cycles in Australia — a figure that reflects both the prevalence of fertility difficulty and the scale of the clinical system designed to address it.² What those numbers do not capture is the group of people who reached specialist care too late, or who never reached it at all, because a GP did not refer them when the guidelines required it.

What standard clinical management requires at each stage

A GP’s role in fertility management is not passive. The Royal Australian College of General Practitioners (RACGP) and the Fertility Society of Australia and New Zealand (FSANZ) both publish guidance on when a GP should investigate fertility concerns and when referral to a reproductive specialist is required. The standard pathway looks like this:

• A woman under 35 who has been trying to conceive for 12 months without success should be referred for specialist assessment.
• A woman aged 35 or over who has been trying for 6 months without success should be referred — not asked to continue trying.
• Any woman with a known risk factor for reduced fertility — including endometriosis, polycystic ovarian syndrome (PCOS), prior pelvic surgery, prior chemotherapy or radiation, irregular menstrual cycles, or a history of pelvic inflammatory disease — should be referred earlier, regardless of how long she has been trying.
• Any woman with an abnormal result on a fertility investigation — including a low AMH, an elevated follicle-stimulating hormone (FSH), or a low antral follicle count on ultrasound — requires prompt specialist referral, not watchful waiting.

Patients are typically told to “keep trying” and to return if nothing has happened after a year. That advice is appropriate for a 28-year-old with no risk factors. It is not appropriate for a 36-year-old with a history of endometriosis. The standard of care is not one-size-fits-all — it is calibrated to the individual patient’s age, history, and test results. A GP who applies the same advice to every patient, regardless of those variables, is not meeting the standard.

The standard of care — what GPs are legally required to do

The “standard of care” in law means the standard of a reasonably competent practitioner in the same specialty, exercising the same level of skill, in the same circumstances. It is an objective test. What this particular GP intended, believed, or hoped for is not the measure. The measure is what a competent GP, properly informed of the patient’s age, history, and test results, would have done.

The High Court of Australia’s decision in Rogers v Whitaker (1992) 175 CLR 479 established that the standard of care in Australia is not determined solely by what a body of medical practitioners would do — it is determined by the court, informed by expert evidence.³ This matters in fertility referral cases because a GP cannot defend a delayed referral simply by pointing to other GPs who would have done the same thing. The court asks whether that practice was reasonable — and in the face of clear guideline thresholds, the answer is often no.

The Bolam test — which allowed a clinician to escape liability if a responsible body of medical opinion supported their conduct — does not apply in Australia in its original form. Australian courts apply the modified approach confirmed in Rogers v Whitaker and later cases: the court retains the power to find that a widespread clinical practice was nonetheless unreasonable.³ For fertility referral delays, this is significant. The fact that many GPs routinely tell patients to “keep trying” does not make that advice legally defensible when the patient’s age and clinical profile required earlier action.

Where care breaks down — specific failure patterns in IVF referral delays

The failures that produce delayed or withheld IVF referrals are not random. They follow recognisable patterns — patterns that appear in complaints to the Health Care Complaints Commission (HCCC) and in the cases that reach NSW courts. Understanding these patterns is essential to understanding whether what happened in a particular case crossed the legal threshold.

Watchful waiting beyond the guideline threshold

The most common failure is the simplest: a GP tells a patient to keep trying naturally, beyond the point at which the guidelines require referral. A 37-year-old woman presents after eight months of trying. The GP says: “Let’s give it a few more months — you’re still young.” She comes back at 14 months. The GP says: “Let’s try a few more things first.” She is 38 by the time anyone orders an AMH test.

That sequence is not cautious medicine. It is a departure from the standard. The guideline threshold for a woman aged 35 and over is six months. At eight months, referral was already overdue. Every additional month of watchful waiting was a month of ovarian reserve that could not be recovered.

The mechanism behind this failure is partly cognitive and partly structural. GPs see fertility concerns as a normal part of reproductive life — something that resolves for most people without intervention. That cognitive frame leads to underweighting the urgency of age-related decline. Structurally, the GP consultation model rewards reassurance and discourages referral for concerns that appear to be within normal variation. Neither factor excuses the failure when the guideline threshold has been crossed.

Failure to investigate known risk factors

A woman with a documented history of endometriosis presents to her GP at age 32, having tried to conceive for four months. The GP notes the endometriosis in the records but does not order fertility investigations and does not refer. She is told to try for another eight months before anyone will look at it.

Endometriosis is a known risk factor for reduced fertility. So is PCOS, prior pelvic surgery, prior chemotherapy, and a history of pelvic inflammatory disease. The guidelines are explicit: the presence of a known risk factor triggers earlier referral, regardless of how long the patient has been trying. A GP who knows about the risk factor and does not act on it has not met the standard.

This failure often reflects a compartmentalised approach to the patient’s history — the endometriosis is managed as a separate clinical problem, and the fertility concern is treated as a fresh issue with its own waiting period. That compartmentalisation is the error. A competent GP integrates the patient’s full clinical picture and applies the appropriate threshold.

Failure to act on abnormal investigation results

A GP orders an AMH test. The result comes back low — below the reference range for the patient’s age. The GP tells the patient the result is “a bit low but not alarming” and does not refer. Six months later, the patient returns. The GP orders a repeat test. The result is lower still. Referral finally happens — 12 months after the first abnormal result.

A low AMH result in a woman of reproductive age is not a finding to monitor. It is a finding that requires specialist review. The antral follicle count on ultrasound and the FSH level provide additional data, but a low AMH alone — particularly in a woman over 35 — is sufficient to trigger referral. A GP who interprets that result as “borderline” and continues watchful waiting has misapplied the clinical standard.

The harm in this pattern is particularly concrete. Expert reproductive medicine evidence can establish what the patient’s ovarian reserve was at the time of the first abnormal result, and what IVF outcomes were statistically probable at that point. The difference between those outcomes and the outcomes achieved after the delay is the measurable harm the law is asked to compensate.

Referral withheld on non-clinical grounds

Some referral delays are not the product of clinical misjudgement. They are the product of a GP’s personal views about the patient’s relationship status, age, lifestyle, or choices. A single woman is told that Medicare does not cover IVF for her circumstances and that she should “think carefully” before pursuing it. A same-sex couple is not offered the same investigation pathway as a heterosexual couple presenting with the same history. A woman in her early forties is told that IVF “probably won’t work” and that she should consider other options — without any specialist assessment having been conducted.

These are not clinical judgements. They are value judgements that substitute for clinical assessment. A GP who withholds a referral on this basis has not applied the standard of care — they have applied their own preferences in place of it. That substitution is a breach.

The Australian Commission on Safety and Quality in Health Care has identified timely referral and care coordination as core elements of safe primary care. Failures in referral pathways — including delayed or withheld specialist referrals — are a documented patient safety concern across the Australian health system.⁴

The legal framework in NSW

Medical negligence claims in NSW are governed primarily by the Civil Liability Act 2002 (NSW). That Act sets out the framework within which a court assesses whether a clinician’s conduct fell below the required standard, and whether that failure caused the harm the plaintiff suffered.

For a detailed overview of how these claims work in practice, Reframe Legal — Medical Negligence sets out the legal framework that applies to medical negligence claims in NSW.

Section 5O — the peer professional opinion defence

Section 5O of the Civil Liability Act 2002 (NSW) provides that a clinician does not breach their duty of care if they acted in a manner that was widely accepted by peer professional opinion as competent professional practice — unless that opinion was irrational.⁵ In plain terms: if a body of GPs would have done the same thing, the clinician may be protected.

But this defence has limits that matter directly in fertility referral cases. First, the opinion must be rational — a widespread practice of telling women over 35 to “keep trying” for 12 months, in the face of guideline thresholds that require referral at 6 months, is not a rational professional opinion. Second, the court retains the power to find that even a widely accepted practice was unreasonable. Third, where the relevant specialist body has published explicit referral thresholds — as FSANZ has — a GP who departs from those thresholds cannot easily claim the protection of peer professional opinion.

Section 5D — causation and the “but for” test

Section 5D of the Civil Liability Act 2002 (NSW) requires the plaintiff to establish that the breach caused the harm.⁵ In fertility referral cases, this is the most legally complex element. The question is: but for the delayed referral, would the outcome have been different?

That question is answered by expert reproductive medicine evidence. A specialist can assess the patient’s ovarian reserve at the time referral should have occurred — using the AMH results and other investigations that were available at that point — and give evidence about what IVF outcomes were statistically probable at that earlier stage. The difference between those probable outcomes and the actual outcomes is the harm the law is asked to address.

Courts in Australia have accepted that loss of a chance — including a reduced statistical probability of a successful pregnancy — can constitute compensable harm in appropriate cases. The causation analysis in fertility cases is not straightforward, but it is not insurmountable. It requires careful expert evidence and a clear factual record of what was known, when it was known, and what a competent clinician would have done with that information.

Who holds the duty of care

In IVF referral delay cases, the primary duty of care rests with the treating GP. That duty arises from the clinical relationship and encompasses the obligation to investigate, to interpret results competently, and to refer when the clinical picture requires it. Where a GP practice employs multiple practitioners and the patient has seen different GPs over time, each practitioner who assessed the patient and failed to refer carries their own duty. The practice itself may carry vicarious liability for the conduct of its employed practitioners.

Where a GP referred to a gynaecologist rather than a reproductive specialist, and the gynaecologist failed to refer on to a fertility clinic, the duty analysis extends to that second clinician. The chain of referral failures is legally relevant — each link in the chain is assessed against the standard applicable to that practitioner’s specialty.

When a delayed or withheld IVF referral may amount to medical negligence

The following scenarios map specific factual situations to the legal elements of negligence. Each is condition-specific. A reader who recognises their own experience in these descriptions should understand that recognition as a prompt to seek proper legal examination of the facts — not as a legal conclusion in itself.

The GP continued watchful waiting after the guideline threshold had passed

If a woman aged 35 or over presented to her GP with fertility concerns and the GP continued to advise natural conception attempts beyond six months — without documented clinical justification for departing from the guideline threshold — that conduct is a potential breach of the standard of care. The breach element is engaged. The causation question then turns on expert evidence about what the patient’s ovarian reserve was at the six-month mark, and what IVF outcomes were probable at that point compared to the outcomes achieved after the delay.

The GP knew about a risk factor and did not refer

If the patient’s medical records document a known fertility risk factor — endometriosis, PCOS, prior pelvic surgery, prior chemotherapy — and the GP did not refer for specialist assessment at the time the fertility concern was raised, that failure is a potential breach. The guidelines are explicit that known risk factors trigger earlier referral. A GP who applies the standard waiting period to a patient with a documented risk factor has not applied the correct standard.

The GP received an abnormal AMH or FSH result and did not refer

If a GP ordered fertility investigations, received a result indicating diminished ovarian reserve — a low AMH, an elevated FSH, or a low antral follicle count — and did not refer to a reproductive specialist, that failure is a potential breach. The result itself was the clinical trigger for referral. A GP who characterised the result as “borderline” or “something to watch” and continued watchful waiting has misapplied the standard. The harm is measurable: expert evidence can establish what the patient’s reserve was at the time of the first abnormal result and what it was by the time specialist assessment occurred.

The GP withheld referral on non-clinical grounds

If a GP declined to refer — or discouraged the patient from pursuing specialist assessment — on the basis of the patient’s relationship status, sexual orientation, age, or personal circumstances, rather than on the basis of a clinical assessment, that conduct is a potential breach. The standard of care does not permit a GP to substitute personal value judgements for clinical assessment. A patient who was told that IVF “probably won’t work” or that they should “think carefully” before pursuing it — without any specialist assessment having been conducted — was not given the clinical assessment the standard requires.

The three elements of negligence applied to IVF referral delays

For a medical negligence claim to succeed in NSW, three elements must all be established: duty of care, breach, and causation. In IVF referral delay cases, all three elements are present in the right factual circumstances — but all three must be established on the evidence. The following diagram sets out how each element applies to this specific condition.

Long-term and permanent harm when IVF referral is delayed

The harm produced by a delayed or withheld IVF referral is not always visible in the way that a surgical injury or a missed cancer diagnosis is visible. But it is real, measurable, and in many cases permanent.

Physical consequences

Ovarian reserve does not recover. Every month of delay during a period of declining reserve is a month that cannot be reclaimed. For a woman whose AMH was already low at the time referral should have occurred, a 12-month delay may mean the difference between a successful egg retrieval and a failed one — or between using her own eggs and requiring donor eggs. For a woman whose underlying condition (endometriosis, for example) progressed untreated during the delay, the physical consequences extend beyond fertility to include ongoing pain, further surgical intervention, and potential damage to adjacent structures.

Where the delay results in the patient being unable to conceive at all — either because IVF is no longer viable or because the window for treatment has closed entirely — the physical harm is the permanent loss of the capacity to have a biological child. That is not a minor harm. It is a harm the law recognises as serious and compensable.

Psychological consequences

The psychological impact of infertility is well documented. Research published in peer-reviewed reproductive medicine literature consistently identifies elevated rates of depression, anxiety, and grief in people who experience infertility — and those rates are higher in people who believe their infertility was avoidable.⁶ The experience of being told to wait, of watching the window close, and of eventually learning that earlier action might have changed the outcome, produces a specific and compounding form of distress that is distinct from the grief of infertility alone.

Psychological harm is compensable in NSW. Where a plaintiff can establish, through psychiatric evidence, that the delay caused or materially contributed to a recognised psychological condition — depression, anxiety disorder, or adjustment disorder — that harm forms part of the damages claim.

Financial consequences

IVF is expensive. According to the Fertility Society of Australia and New Zealand, a single IVF cycle in Australia costs between $8,000 and $10,000 out of pocket after Medicare rebates, depending on the clinic and the patient’s circumstances.⁷ A patient who required additional cycles because of diminished ovarian reserve — cycles that would not have been necessary had referral occurred earlier — has suffered a quantifiable financial loss. A patient who required donor eggs — at significantly higher cost — because her own eggs were no longer viable by the time treatment began, has suffered a larger financial loss still.

Beyond the direct cost of treatment, financial harm includes lost income during treatment cycles, the cost of ongoing psychological support, and — where the patient is ultimately unable to have a biological child — the costs associated with alternative pathways to parenthood, including adoption or surrogacy.

What compensation covers in NSW

Compensation in a successful medical negligence claim in NSW covers two broad categories: general damages and special damages. General damages compensate for pain, suffering, and loss of enjoyment of life — including the grief and distress of infertility caused or worsened by the delay. Special damages compensate for quantifiable financial losses: past and future medical expenses, lost income, and care costs.

Under section 16 of the Civil Liability Act 2002 (NSW), non-economic loss (general damages) is only compensable if the severity of the harm exceeds a statutory threshold — currently set at 15% of a most extreme case.⁵ In practice, this threshold is relevant to the quantum of general damages, not to whether a claim can be brought. A plaintiff whose harm falls below the threshold may still recover special damages for quantifiable financial losses.

The limitation period under the Limitation Act 1969 (NSW) is generally three years from the date the cause of action accrues.⁸ In cases involving latent harm — where the full extent of the harm was not discoverable at the time of the negligent act — the limitation period may run from the date of discovery. In fertility referral cases, the date of discovery is often the date on which the patient first received specialist advice that their ovarian reserve had declined to a point where earlier referral would have made a difference. Legal advice about limitation periods should be sought promptly.

These figures are general reference ranges only. Each case turns on its own evidence — medical records, expert clinical opinion from a reproductive medicine specialist, psychiatric evidence, and economic reports that quantify the actual financial loss.

How to think about your own situation

The following questions are designed to help you think clearly about whether your experience may warrant further examination. They are not a legal test. They are prompts — drawn from the specific failure patterns that appear in IVF referral delay cases — that help identify whether the clinical standard may not have been met.

These questions are not a legal test. But the pattern they reveal — when several of them point in the same direction — is often the starting point for a proper examination of whether the standard of care was met. The medical records will show what the GP knew, when they knew it, and what they did with that information. That is the evidentiary foundation of any legal analysis. For a detailed explanation of how that process works, Reframe Legal — How Medical Negligence Claims Work in NSW sets out the steps involved.

Uncertainty is normal — and it does not mean nothing went wrong

Most people who experienced a delayed IVF referral do not feel certain that something went wrong. They feel confused. They trusted their GP. They followed the advice they were given. They wonder whether they should have pushed harder, asked more questions, or gone somewhere else sooner. That self-doubt is a rational response to a confusing experience — not evidence that the care they received was adequate.

The law does not ask how certain the patient feels. It asks what a competent GP, with the same information, in the same circumstances, would have done. That is an objective question. It is answered by examining the medical records, applying the clinical guidelines, and obtaining expert evidence from a reproductive medicine specialist about what the standard required at each decision point.

Many people in this situation waited a long time before seeking any kind of examination of the facts. Some were discouraged by those around them. Others assumed that because the GP was well-intentioned, nothing could have gone wrong legally. Good intentions do not determine the standard of care. The standard is objective — and it is set by the profession itself, in the guidelines it publishes and the training it requires of its practitioners.

Where informed consent is also in question — for example, where a GP failed to advise a patient of the risks of delayed referral given their age or clinical profile — the legal analysis extends to the consent framework. Reframe Legal — Informed Consent and Medical Negligence explains what the law requires in that context. Regulatory complaints about a GP’s conduct can also be directed to AHPRA — Australian Health Practitioner Regulation Agency, which oversees the registration and conduct of medical practitioners in Australia.

Dr Rosemary Listing is a lawyer with a PhD in law, specialising in medical negligence. Her legal practice concentrates on cases where clinical care in NSW failed to meet the standard the law and the profession require. Her doctoral research and legal practice have given her a rigorous command of the clinical standards against which negligent conduct is measured, and of the evidentiary requirements those claims must satisfy in NSW courts.

Cases involving delayed or withheld IVF referrals sit at a legally and clinically complex intersection. The clinical standard is set by published guideline thresholds — thresholds that are specific, age-calibrated, and risk-stratified. The legal threshold requires establishing not only that those guidelines were not followed, but that the departure caused measurable harm to reproductive outcomes. That causation analysis demands expert reproductive medicine evidence of a kind that most people — and many lawyers — are not equipped to assess without specialist input.

The cases that have reached NSW courts, and the complaints recorded by the HCCC, reveal a consistent pattern in how IVF referral failures occur: a GP applies a standard waiting period to a patient whose age or clinical profile required earlier action, receives an abnormal investigation result and does not refer, or allows personal views about the patient’s circumstances to substitute for clinical assessment. That pattern is recognisable in the records — and the records are where the legal analysis begins.

The people who seek a legal examination of their records in these cases are not looking to blame anyone. They want to understand whether the time they lost — time that cannot be recovered — was lost because of a failure that the law recognises. Many waited years before asking that question, often because they doubted themselves, or because the experience of infertility is already so isolating that adding a legal question to it felt like too much.

Dr Listing examines medical records alongside expert clinical opinion and applies the legal standard — not to assign blame, but to give people an honest answer about whether what happened to them met the benchmark the profession sets for itself. That answer, whatever it is, is what most people are actually seeking.
