AMH is a hormone released by your developing egg sacs (ovarian follicles). Your AMH levels are a good indicator of how many eggs you have left — your ovarian reserve.
AMH levels naturally decline with age, usually starting in your mid-20s. Low AMH levels in younger women might indicate lower remaining follicles and a smaller ovarian reserve.
Causes of low AMH levels include:
An AMH test can’t directly predict your fertility or the time it will take to conceive. But it’s helpful if you’re considering family planning, freezing your eggs, or IVF.
Your test kit arrives in 1-2 days with instructions on how to take your sample. Then free post it back to the lab.
You'll get a GP-reviewed report and personalised recommendations to improve or maintain your results.
From lifestyle tips to dietary advice or premium supplements, follow your personalised advice to support your health.
“You’re born with a set number of eggs — up to 1-2 million. The more eggs you have left, the higher your AMH levels will be."
