What does your AMH result actually mean? This guide explains AMH levels by age, what low or high results indicate for your fertility, and what to do next.
Quick Answer: Normal AMH for women aged 25–35 is 1.0–3.5 ng/mL. Below 1.0 ng/mL = low ovarian reserve. Below 0.5 ng/mL = very low. Above 3.5–4.0 ng/mL may indicate PCOS. AMH declines naturally with age — getting tested early and acting on low AMH is the most important step you can take for your fertility.
AMH naturally declines with age. What is "normal" at 28 would be "good" at 38. Use this chart as a reference — your own result should always be interpreted by a specialist in the context of your full clinical picture.
| Age Group | Normal Range (ng/mL) | Normal Range (pmol/L) | Ovarian Reserve |
|---|---|---|---|
| Under 25 | 2.0 – 6.8 | 14.3 – 48.5 | Excellent |
| 25–30 | 1.5 – 4.0 | 10.7 – 28.6 | Very Good |
| 30–35 | 1.0 – 3.5 | 7.1 – 25.0 | Good |
| 35–37 | 0.7 – 2.5 | 5.0 – 17.9 | Moderate |
| 38–40 | 0.5 – 1.5 | 3.6 – 10.7 | Reduced |
| 40–43 | 0.2 – 1.0 | 1.4 – 7.1 | Low |
| 43+ | < 0.2 – 0.5 | < 1.4 – 3.6 | Very Low |
| PCOS (any age) | > 3.5 – 4.0+ | > 25 – 29+ | Elevated (PCOS) |
*Reference ranges may vary slightly between laboratories due to different assay methods. Always interpret results alongside your AFC ultrasound and clinical history.
Good ovarian reserve for your age. You have a reasonable pool of eggs for stimulation. If trying naturally, continue — IVF is not urgent. If planning IVF, timing is not critical but earlier is always better.
Ovarian reserve is declining. You may not respond as strongly to stimulation. Consultation recommended to plan timeline. If IVF is being considered, do not delay significantly. Pre-IVF supplements may help.
Diminished ovarian reserve. Fewer eggs available for retrieval. IVF success is possible but requires a specialised protocol. DHEA and CoQ10 pre-treatment, micro-stimulation, and careful cycle planning improve outcomes. Act promptly.
Very few or no follicles responding. IVF with own eggs may still be attempted with aggressive support. A full evaluation including AFC scan and hormonal profile is essential. Donor egg IVF may be discussed if needed.
Many follicles present — often seen in PCOS. High egg count but risk of over-response (OHSS) with stimulation. Protocol must be tailored carefully. A Freeze-All approach is typically recommended to prevent OHSS.
If your AMH is low for your age group — e.g., a 28-year-old with AMH of 0.8 ng/mL — further investigation is needed. Possible causes include previous surgeries, autoimmune conditions, or early onset diminished reserve.
Anti-Müllerian Hormone (AMH) is produced by the granulosa cells of small follicles in the ovaries. It reflects the number of follicles available — which represents how many eggs you have in reserve. The higher your AMH, the more follicles (and eggs) remain.
Unlike FSH, AMH is stable throughout the menstrual cycle and can be tested on any day. It is currently the most reliable single marker of ovarian reserve.
AMH tells you quantity — how many eggs you have. It does not tell you about egg quality, which is mainly determined by age. A woman with low AMH may still have excellent egg quality if she is young. Conversely, a woman with normal AMH at 41 may have age-related egg quality issues.
AMH also does not predict miscarriage risk, determine sperm quality, or guarantee IVF success.
AMH testing is recommended if:
This is one of the most common questions we receive. The honest answer is nuanced.
Honest answer: AMH levels cannot be significantly or permanently increased by any supplement or lifestyle change. Once follicles are lost, they cannot be restored. However, certain supplements — particularly DHEA and CoQ10 — may support the function of remaining follicles, potentially improving egg quality and response to stimulation. The most powerful action you can take is acting early while your reserve is still usable.
The best response to low AMH is a specialist consultation to create a timely, individualised treatment plan.
