There is no absolute predictor of fertility

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


You are not sure if you want kids - your focus is building up your career, exploring the world, discovering yourself. But understanding your hormones empowers you to better plan your future.

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

"From a young age, we teach women how we can protect ourselves against pregnancy.  But we are not educated with, if you are ready, whether everything 'works' to get pregnant". That’s why I got my Grip test."

Sue-Jeen is not on hormonal birth control.


 "Why would I have to try to get pregnant, before I can get insight into my own body?


I'm aware that I shouldn't wait 10 more years, but really - I don't know how long I do have. To get some idea of that, I took a Grip test."

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 fertility related issues 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.
