Understand your Egg Count

Whether you want kids, don’t want kids, have kids or aren’t sure yet, understanding your egg count – aka ‘ovarian reserve’ – helps you better understand your body.

Get started

We measure your AMH (Anti-Mullerian hormone) which is the same test used by doctors and fertility clinics worldwide to assess ovarian reserve.

You’ll find out if you have more or less eggs than would be expected for someone of your age and if you are at risk of running out of eggs early. This can help you make more informed decisions that support your family planning goals.

Your results are delivered on a report built by fertility specialists.
