There is no absolute predictor of fertility

"We can’t tell you if you’ll be able to get pregnant, and neither can any doctor. There's also no predictor of infertility, so we won't be able to tell you that you can't have kids either.

We've developed the Grip test with some of the world’s leading reproductive endocrinologists and gynaecologists. Think of your Grip test as a risk profile, rather than a yes or no answer. If you know your risks when you’re still young, then you still have all the options to do something about them."

What we can tell you

  • If you have a normal amount of eggs for your age

  • If you are at risk of going into menopause early

  • If you are at risk of blocked tubes

  • If you are at risk of PCOS

  • If your thyroid is working well

  • If you're a good candidate for egg freezing or IVF

What we can't tell you

  • If you are fertile

  • Your chance of having a baby

  • How long it will take you to get pregnant

  • If your eggs are high quality


Egg count & early menopause

Biology 101? 

If you have ovaries, then you were born with all the eggs you’ll ever have. Every month you lose thousands as your body prepares for releasing one during ovulation. Menopause is when you have released all your eggs, and your ovarian reserve is empty. 

Why does it matter? 

About 1 in 100 people suffer from early ovarian failure, which basically means you enter menopause before 45. The hormone AMH correlates with the number of follicles that you have left in your ovarian reserve, and is the most reliable predictor that we’ve got. AMH can help you understand how large (or small) your fertile window is. It’s not a perfect predictor, but it’s a useful datapoint.

* if your AMH is low, then you have about 30% chance of early menopause

What does Grip test?

Are your hormones healthy? 

Why finger-prick testing works

The results from a traditional blood draw and the finger-prick method that we use are completely comparable, and have been fully medically validated


We only work with labs that are ISO15189 and CQC regulated, making sure your sample gets treated with care and that your sample gets destroyed after 5 days. 

If you still don’t feel like finger pricking is for you, you can also get your blood drawn by a nurse.

Who shouldn't take a Grip test?

We want to be transparent, so here's who we don't think will benefit from a Grip test: 

• If you are younger than 23 or older than 43, because most of the research we base our reports on hasn't been validated for you. 

• If you have been trying to conceive for a while (e.g. >9 months), because you might get a similar test for free at your GP within 3 months. 

• If you know you have PCOS or Endometriosis, as it's unlikely that we'll tell you something you don't already know. 

• If you’re using specific medication that impacts your hormones. You can always email us on hello@heygrip.com to check!
