First up, if you’re wondering if this test will tell you if you can have a baby, the answer is No.

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. 


What we can do is help you exclude the most common reasons why women struggle to conceive. That still doesn’t guarantee you a baby, but it’s a good starting point. 


In the Netherlands alone, about 30.000 women come to a fertility clinic each year. In line with the NGH Subfertility standards, these are the main reasons why they struggle to conceive:




Blocked tubes




Egg count


We test LH, AMH, testosterone

Biology 101? 

Ovulation is the process that your body goes through to release an egg each month. If you don’t release an egg, then you can’t get pregnant.

Why does it matter? 

1 in 10 women suffer from PolyCystic Ovarian Syndrome, a condition that makes ovulation unpredictable, and sometimes stops it entirely. We’re still unsure what the exact cause of PCOS is, but we know that testosterone has a lot to do with it. Having a high T value, in combination with having high AMH and low LH, gives you about 75% certainty that you suffer from PCOS. 

Blocked tubes

We test Chlamydia IgG

Biology 101? 

Once you release an egg through ovulation, and that egg gets fertilised by a sperm, it needs to travel down your fallopian tubes to get to the uterus. You can’t get pregnant if the fertilised egg can’t get through the tubes. 

Why does it matter? 

60% of blocked tubes are because of scarring due to infections that you’ve once had, and the most common infection is chlamydia. We test your blood for antibodies against chlamydia, to see if you’ve once had it. That of course doesn’t mean that your tubes are blocked, but if you’re surprised to test positive, then you may want to have a think. The only way to prove that your tubes are blocked is through an HSG test, an invasive procedure where a doctor puts a dye in your fallopian tubes, and sees if it comes out on the other side.


We test TSH

Biology 101? 

Your thyroid is a gland that produces hormones which regulate a tonne of things in your body. It can be over- or underactive, causing a bunch of issues. Once diagnosed, thyroid issues are easy to treat and manage. 

Why does it matter? 

1 in 6 women suffer from thyroid issues, often undiagnosed. Having an under- or overactive thyroid makes it hard to get pregnant, and puts you at risk of having a miscarriage. It’s worth finding out if your thyroid is off, in particular given how easy it is to treat it. A normal TSH level means that your thyroid functions well.  

Egg count

We test AMH

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 women suffer from early ovarian failure, which basically means you enter menopause under 40. 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.

What we can't tell you

  • If you are fertile

  • Your chance of having a baby

  • How long it will take you to conceive

  • If your eggs are high quality

What we can tell you

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

  • If you might enter menopause early

  • If you seem to ovulate 

  • If you have a higher risk of blocked tubes

  • If you have a higher risk of PCOS

  • If your thyroid is working well

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

We test the same hormones as a fertility clinic would


Anti-Mullerian Hormone is produced by cells from the small follicles in a woman’s ovaries and is used as a marker of egg quantity.

Chlamydia IgG

Chlamydia Trachomatis IgG are the antibodies that remain in the body after it's fought off a chlamydia infection. It doesn't pick up current chlamydia infections. 


Luteinisizing Hormone

is responsible for triggering monthly ovulation, and used in the diagnosis of PCOS. 

Total T

Testosterone is often thought of as a male hormone, but women also produce small quantities. An imbalance in testosterone can indicate PCOS.


Thyroid Stimulating Hormone helps diagnose thyroid disorders: hypothyroidism and hyperthyroidism.
