You’re 34, not ready for kids yet, but wondering whether you should be worried about your “biological clock.” A friend mentions she had an AMH test, and a fertility clinic ad promises to show you how many eggs you have left. Should you get tested?
An AMH test can give useful information about your ovarian reserve, a measure related to your egg supply. It can be especially helpful during fertility treatment. But it can’t tell you whether you’ll get pregnant, how good your eggs are, or give you a personal deadline. Knowing what it does (and doesn’t) show helps you decide whether it’s right for you.
What is AMH?
AMH stands for anti-Müllerian hormone. It’s made by cells in small, developing follicles in your ovaries, and those follicles contain immature eggs. A blood test for AMH gives doctors information related to ovarian reserve. It doesn’t literally count every egg you have left. MedlinePlus explains AMH testing and its uses.
Ovarian reserve is about egg supply. That’s different from egg quality, and from the many other factors involved in getting and staying pregnant.
Where AMH is genuinely useful
AMH can help doctors estimate how your ovaries might respond to stimulation during fertility treatment, such as IVF or egg freezing. The American Society for Reproductive Medicine explains that reserve markers can help predict how many eggs may be retrieved, but they’re poor predictors of your chance of pregnancy on their own. Read ASRM’s ovarian-reserve guidance.
In other words: “How might I respond to treatment?” and “What are my chances of conceiving naturally?” are different questions, and AMH mainly helps with the first.
Common myths about AMH
Scroll sideways to see all columns.
| Myth | A better question |
|---|---|
| “It’s my fertility score.” | Which part of fertility does this actually measure? |
| “Low AMH means I can’t get pregnant.” | What can this result really predict in my situation? |
| “High AMH means I can wait as long as I like.” | What does AMH leave out about age and future fertility? |
| “It predicts when I’ll reach menopause.” | How uncertain is any timing prediction? |
ACOG advises against using a single AMH result to predict how long it will take to get pregnant in women who haven’t been diagnosed with infertility. It also explains the limits of using AMH to predict menopause. See ACOG’s committee opinion on AMH outside fertility care.
Why age charts can mislead
AMH generally declines with age, but an average for your age group isn’t a personal forecast. Different labs use different methods and ranges, which also affects how results compare. Before comparing your number with a friend’s, find out what question each test was meant to answer. A higher number isn’t automatically “better.”
What you can do: questions to ask before (or after) testing
- Why would AMH be useful in my situation?
- Are we planning for possible treatment, or trying to answer a different question?
- What can’t this result tell us?
- What other information matters for my plans?
- Would repeating the test change any decision?
If you’re thinking about your future fertility in general, it can help to talk with a doctor about your age, health history, and plans. That conversation often tells you more than any single number.
Frequently asked questions
What is a good AMH level?
There’s no single “good” number for everyone. Results depend on age, the lab method, and why the test was done.
Can I get pregnant with low AMH?
Yes, it’s possible. AMH reflects egg supply, not your chance of pregnancy on its own.
Should I test AMH if I’m not trying to conceive?
Professional guidance cautions against using AMH alone to predict future fertility for women who aren’t seeking fertility care. Discuss your goals with a doctor first.
