For women thinking about their fertility — whether planning a family now, in the future, or simply wanting to understand their reproductive health — Anti-Müllerian Hormone (AMH) is one of the most informative tests available. AMH provides a direct window into ovarian reserve: the quantity of eggs remaining in the ovaries. It is one of the earliest and most sensitive markers of reproductive ageing, and it can be measured at any point in the menstrual cycle.
What Is AMH?
Anti-Müllerian Hormone is produced by the granulosa cells of small, developing follicles in the ovaries. Because AMH is secreted continuously by these follicles, its level in the blood reflects the size of the remaining follicle pool — in other words, how many eggs are left. Unlike FSH and oestradiol, which fluctuate significantly across the menstrual cycle, AMH is relatively stable and can be tested at any time.
What Does AMH Tell You?
- High AMH: Indicates a larger follicle pool and greater ovarian reserve. Very high AMH can also be a marker of PCOS (polycystic ovary syndrome).
- Normal AMH: Suggests ovarian reserve is appropriate for age.
- Low AMH: Indicates diminished ovarian reserve — fewer eggs remaining. This does not mean pregnancy is impossible, but it may affect the timeline and approach to conception.
AMH declines naturally with age, but the rate of decline varies significantly between individuals. Some women in their early 30s have AMH levels typical of women in their 40s — and vice versa. This is why chronological age alone is a poor predictor of fertility potential.
AMH and PCOS
Women with PCOS typically have significantly elevated AMH levels, reflecting the large number of small antral follicles characteristic of the condition. While high AMH in PCOS indicates a larger egg pool, it also signals disrupted follicle development and ovulation — which is why PCOS is a leading cause of female infertility despite high ovarian reserve.
When Should You Test AMH?
- You are considering delaying pregnancy and want to understand your reproductive timeline
- You have been trying to conceive without success
- You have a family history of early menopause
- You have had ovarian surgery, chemotherapy, or radiotherapy
- You are considering egg freezing or IVF
- You have symptoms of PCOS or irregular cycles
- You simply want a baseline understanding of your reproductive health
Testing AMH at Home
Our Anti-Müllerian Hormone (AMH) Fertility Test Kit provides a clinical-grade AMH measurement from a simple at-home dried blood spot sample. No clinic visit, no GP referral, no waiting. Results are returned within 3–5 working days with specialist commentary to help you understand what your AMH level means for your individual situation.
AMH in Context: The Broader Hormonal Picture
AMH is a powerful marker, but fertility is influenced by multiple hormonal systems. LH and FSH govern the menstrual cycle and ovulation; oestrogen and progesterone support implantation and early pregnancy; thyroid function affects cycle regularity and miscarriage risk; and cortisol can suppress reproductive hormones under chronic stress.
For women who want a comprehensive view of their reproductive and hormonal health, our Comprehensive Female Saliva Hormone Profile (LCMS) assesses the full spectrum of female hormones alongside cortisol — providing the context that AMH alone cannot offer. Our Advanced Female Wellness Test goes further still, combining hormonal, thyroid, and metabolic assessment with a specialist doctor report.
Frequently Asked Questions
Can AMH predict when I will reach menopause?
AMH can provide an indication of reproductive lifespan, but it cannot predict the exact timing of menopause with certainty. It is best used as one data point within a broader assessment of reproductive health.
Does a low AMH mean I cannot get pregnant naturally?
Not necessarily. Low AMH indicates fewer eggs remaining, but egg quality — which AMH does not measure — is equally important for conception. Many women with low AMH conceive naturally.
Can AMH levels improve?
Ovarian reserve naturally declines with age and cannot be significantly reversed. However, optimising overall hormonal health, reducing oxidative stress, and addressing nutritional deficiencies may support egg quality.
