AMH testing: what the results really mean for your patients

Anti-Müllerian hormone (AMH) testing has become one of the most commonly ordered fertility investigations in general practice. It is accessible, relatively inexpensive, and gives a measurable indication of a woman's ovarian reserve - the number of eggs remaining in the ovaries. But as its use has grown, so too has the potential for misinterpretation. A low AMH result does not mean a patient cannot conceive naturally. A normal AMH does not guarantee fertility. And the clinical decisions that follow an AMH result are rarely straightforward.

In this episode of Fertility in General Practice, Dr Andrew Wong - obstetrician, gynaecologist and fertility specialist at Genea Orange - joins host Dr Ali Hodgkinson to cut through the uncertainty around AMH testing. He addresses how GPs can use AMH as a meaningful part of the clinical picture, what the results do and do not indicate, and how to have clear, honest conversations with patients about what comes next.

What AMH measures - and what it does not

AMH is produced by small follicles in the ovaries and reflects the size of the remaining egg pool - what clinicians refer to as ovarian reserve. It is useful because it is relatively stable across the menstrual cycle, can be tested at any time of the month, and correlates reasonably well with how a patient is likely to respond to ovarian stimulation during an IVF cycle.

What AMH does not measure is egg quality. A patient with a low AMH may still have eggs of good quality; a patient with a high AMH is not necessarily more likely to conceive. Age remains the strongest predictor of egg quality, and it is important that GPs contextualise AMH results alongside the patient's age rather than treating the number in isolation.

AMH results are also influenced by factors including hormonal contraception (which can suppress AMH levels), vitamin D status, and certain medical conditions such as polycystic ovary syndrome (PCOS), which can artificially elevate AMH. A high AMH result in the context of PCOS does not reflect a fertility advantage - it reflects a higher number of small, often anovulatory follicles.

Listen to the episode

Dr Andrew Wong brings over three decades of regional fertility practice to this conversation, along with a clear, myth-busting approach to one of the most misunderstood tests in general practice. If AMH results are a regular source of patient questions in your clinic, this episode is essential listening.

About Dr Andrew Wong

Dr Andrew Wong has been practising in Orange, New South Wales, for over 30 years - a commitment to regional fertility care that is rare and genuinely significant for patients in rural and remote NSW. He trained in obstetrics and gynaecology in Newcastle and Penrith after graduating from the University of Sydney, and has been working with Genea (formerly Sydney IVF) since January 2003, treating patients at Dudley Private Hospital in Orange.

His practice spans general gynaecology with a particular focus on fertility and IVF, and he also consults in Bathurst. Beyond his clinical work, Dr Wong is a senior clinical lecturer with the University of Sydney School of Rural Health and currently serves as head of department at Orange Health Service - a role that reflects his investment in building clinical capacity across regional NSW.

His dual perspective as both a specialist and an educator gives him a distinctive ability to translate complex fertility concepts into practical, accessible guidance - exactly the kind of conversation this podcast series is designed to support.
