The Biology Does Not Wait for the Right Moment
Ovarian reserve — the quantity and quality of a woman’s remaining egg supply — declines with age as a natural and irreversible biological process. This is not a new or controversial finding. It is a fundamental of reproductive physiology, and it has meaningful clinical implications for conception probability, IVF response, and fertility
treatment options. What is less well understood by the general population — and often insufficiently
communicated in primary healthcare settings — is the nature of that decline. It is not linear. It is not predictable from the outside. And it does not announce itself with symptoms. A woman in her mid-thirties with dramatically reduced ovarian reserve may be entirely asymptomatic. Her cycles may be regular. She may have no clinical reason to suspect that her reproductive window is narrower than she assumes. And if she is not tested until she is actively trying to conceive — which is, in most healthcare systems, when testing is first offered — she may be working with significantly less time and fewer options than she realised.
What Ovarian Reserve Testing Can and Cannot Tell Us
Anti-Müllerian hormone (AMH) and antral follicle count (AFC) measured via transvaginal ultrasound are the most clinically validated tools for ovarian reserve assessment. They provide a reasonable estimate of a woman’s remaining ovarian reserve — not a prediction of pregnancy, and not a definitive measure of egg quality, but a meaningful indication of where a patient sits on the spectrum from normal to diminished reserve. It is important to communicate clearly what ovarian reserve testing is and is not. A low AMH does not mean a woman cannot conceive — it means her window may be narrower and her response to ovarian stimulation may be reduced. A normal AMH does not guarantee conception — it does not assess egg quality, tubal function, uterine receptivity, or male factor. Testing should always be interpreted in clinical context, not in isolation. What ovarian reserve testing can do, when accessed at the right time, is give a patient information that allows her to make genuinely informed decisions — about timing, about fertility preservation, about when to seek specialist input rather than
waiting.
The Case for Proactive Testing
There is a growing professional conversation about the value of baseline fertility health checks for women in their late twenties and early thirties — before they are actively trying to conceive, but at a point where the information can meaningfully inform their reproductive planning. The argument is not that every woman at 28 needs to be alarmed about her fertility. It is that baseline testing at an age when options are broadest gives women
something precious: information in time to act on it. For a woman in her late twenties who discovers significantly reduced ovarian reserve, this information may shape decisions about fertility preservation, about the timeline for starting a family, and about when to seek specialist advice. Without that information, she may not discover the picture until she has been trying to conceive for a year or more — at which point her range of options may be meaningfully narrower.
The Role of Primary Care
Fertility health conversations in primary care settings remain inconsistent across most healthcare systems. In many contexts, fertility is simply not on the clinical agenda until a patient presents after unsuccessful attempts to conceive. The opportunity to introduce fertility awareness earlier — as a routine component of women’s reproductive health conversations — is largely untaken. This is a gap that extends beyond fertility clinics. It involves GPs, gynaecologists, occupational health professionals, and any clinician who has regular contact with
women of reproductive age. The question ‘have you ever thought about your fertility health?’ is a simple, low-risk, high-potential opening. It should be asked more often.
Information Is Not Alarm — It Is Empowerment
The goal of earlier fertility testing and education is not to create anxiety. It is to give people the information they need to make decisions that are genuinely informed, rather than decisions made on assumptions — cultural, social, or biological — that may not reflect their individual situation. Fertility literacy, in clinical settings and beyond, is one of the most impactful contributions the reproductive medicine field can make to the communities it serves.
