There is no absolute predictor of fertility.

But there's a bunch of things we can test. 

Grip helps you exclude the most common reasons why women struggle to conceive, just like fertility clinics would.

And your risk of early menopause


The most common cause of ovulation issues in women

"We're taught to avoid pregnancy from a young age, but no one ever really talks about how important it is to think about your fertility for when you are ready. I would love to have kids, but I am currently single and so I worry about my fertility declining.


I just want to know what's going on in my body, without needing to have been trying to get pregnant for 12 months."⁠


"I'm not stupid - I know that I shouldn't wait another 10 years. Or rather, I don't really know that at all. That's why I did a Grip test. 


It's reassuring to see that at least for this 35-year-old-who's-not-yet-ready everything as far as we can tell looks good. I know that doesn't mean I can afford to wait, but it's useful information about my body."

"Hearing about the Grip test was a wake up call for me. If I were to find out later that I should have made different choices now, then I’d be devastated. I feel so much more at ease now I don’t have to go through life thinking ‘what if’.

I feel like I have a way more realistic idea of my fertility now. I'm glad there's a way to take control, to get more information about if and how my body works."

How Grip works

You can take the test from the comfort of your home

01. Get the kit

02. Collect your


03. Lab analysis

04. Your plan of action

Answer a few questions, we'll customize your test based on your birth control.

So yes, you can take the test if you're on birth control.

Prick your finger, collect about 10 drops (0.5ml) of blood, and pop your sample in the mail. That's it!

Our lab, the same ones fertility clinics use, analyses your blood sample. 

Our lab is ISO15189 certified, the highest possible medical certification in Europe.

Your results are just the start. Most hormonal imbalances are easily treatable, as long as you have time. Our doctors will make a (free) plan with you, and you can ask all your questions in our closed chat group.

How we protect your data.

We understand how sensitive your information is, and we work very hard to keep everything as safe as possible. The lab uploads your results to a special medical cloud, and the only way that we can see your report is through 2-factor authentication. Only medical professionals have access to your report.


We are GDPR compliant, which means that we won't store any of your data unless you give us explicit permission to do that. Most women want us to store their information so that if you test again next year, we can easily compare your results.


We ask everyone to opt in to giving us an anonymised version of your results for fertility research, but if you don't want to participate, you, of course, don't have to.
