AMH tells you about quantity — not quality
Anti-Müllerian hormone (AMH) is produced by small follicles in the ovaries and is used as a marker of ovarian reserve — in simple terms, how many eggs remain. A result below roughly 1.0 ng/mL is typically labelled "low AMH" or "diminished ovarian reserve." Clinics often use it to predict IVF response, and for many women receiving a low number, the conversation stops there.
But AMH has a critical limitation: it says nothing about egg quality. A woman with AMH of 0.4 ng/mL may still produce one excellent egg per cycle. That one egg is all you need. The number on the lab report is not your fertility.
Four groups of women with low AMH
Not all low-AMH situations are alike. In clinical practice, we see four distinct groups, and realistic expectations differ significantly between them.
1. Women under 35 with unexpectedly low AMH
A young woman with low AMH is often the most treatable case. Her egg quality is typically still strong — the challenge is quantity. With targeted herbal support to nourish ovarian function, we frequently see AMH levels rise over three to six months, and natural conception is a realistic goal. Youth is a powerful counterweight to a low number.
2. Women over 43 with severe decline
When AMH is very low and age is over 43, the honest answer is that the picture is harder. Egg quality and quantity both decline with age, and that combination limits outcomes. We do support women in this group — but the conversation centres on optimising what is there rather than promises of reversal. Some conceive; many find that donor egg becomes the clearer path.
3. Women over 43 with relatively good reserve
Occasionally a woman over 43 has surprisingly decent AMH for her age — perhaps 0.8–1.2 ng/mL. This group often responds well to treatment. The reserve has not yet collapsed, and strengthening the foundation can yield meaningful improvements in egg quality. These patients frequently surprise their IVF consultants.
4. Women aged 35–42 with low AMH
This is the largest group we see, and arguably the one with the most to gain. Reserve is reduced but not gone. Egg quality, while not what it was at 28, is still viable. With several months of herbal medicine — improving circulation to the ovaries, restoring hormonal rhythm, and rebuilding core energy — natural conception is common, and IVF outcomes improve markedly.
Can egg quality be improved?
Yes — with caveats. Egg quality is partly determined by the follicular environment in the months before an egg is ovulated. That environment can be influenced. Better blood flow to the ovaries means better delivery of the nutrients and hormones that support egg maturation. Reduced oxidative stress means less cellular damage during development.
Chinese herbal medicine works on both of these mechanisms. Peer-reviewed research supports its use in diminished ovarian reserve: a 2025 systematic review in the Journal of Ovarian Research found that herbal formulas significantly increased AMH levels, raised antral follicle counts, and reduced FSH in women with low reserve. A separate 2025 study found live birth rates of 32% with herbal medicine alone versus 5% in untreated controls — among women with the same low-reserve diagnosis.
These are not guarantees. They are real signals that the biology is responsive to the right support.
You only need one golden egg
One of the most liberating reframes in fertility medicine is this: you do not need a full cohort of eggs. You need one. One egg that fertilises well, divides cleanly, implants, and grows.
Women with AMH of 0.3 ng/mL conceive naturally. Women with AMH of 0.5 ng/mL produce the single embryo that becomes their child after two years of trying. The path is often narrower — each cycle matters more — but it is not closed.
The clinical work is about creating conditions where that one egg has the best possible environment to mature: nourished, well-circulated, hormonally supported.
What treatment looks like
Our approach for low AMH combines personalised herbal medicine with detailed cycle tracking. There is no one-size-fits-all formula — a 36-year-old with AMH of 0.6 ng/mL and cold extremities needs a very different formula to a 40-year-old with AMH of 0.4 ng/mL and heat signs.
Treatment typically runs for three to six months before reassessment. We look for:
- Improved cycle regularity and menstrual pattern
- Rising AMH on repeat testing (common but not universal)
- Stronger ovulation signals on cycle tracking
- Improved response on the next IVF stimulation, if applicable
Many patients come to us after being told IVF is their only option, or after IVF has failed due to poor response. A period of herbal preparation — three to six months — often changes the picture at the next egg collection.
Why this matters
A low AMH result is the beginning of a conversation, not the end of one. The number tells you something about where your ovaries are today. It does not tell you where they can be in six months with the right support, and it does not determine whether you will become a parent. For the women in the 35–42 group especially, early action — rather than waiting and watching — is what changes outcomes. If you have received a low AMH result and want to understand your specific situation, we offer a free initial assessment.
