How can a fertility blood test help?

If you’re planning to start a family or are struggling to conceive, a fertility blood test can help you understand why. It checks key hormones related to fertility and your ovarian reserve (the number of healthy, immature eggs in the ovaries), which can help you figure out why you’re struggling to get pregnant or help you plan for the future. The test can also be done at home, making it an affordable and easy way to understand your fertility. For a more in-depth view, you can use our innovative hormone mapping product, MyFORM.

How long do fertility blood test results take?

Once you’ve collected your blood sample and sent it back to our lab free of charge, it takes up to 2 working days to get your results once your sample has arrived at our lab. You’ll get a report showing your hormone levels and where they sit within the optimal range for your age, as well as comments and advice from our team of expert doctors, so you can confidently take the next steps to starting a family.

How to test your fertility at home

Our at-home fertility blood test for women makes it quick, easy and convenient to understand your fertility. The test works by analysing a small sample of your blood to check 7 key hormones that affect fertility, including progesterone, FSH and TSH. The kit includes everything you need to collect a blood sample at home and post it back to our labs for analysis. You’ll get the results in just a couple of days of the sample reaching our lab, along with comments and advice from our medical team, helping you to take full control of your fertility.

Frequently asked questions​

This is what our customers ask us most about this test. For more information, try our help centre.

  • What is a female fertility test?

    The Female Fertility Test from Forth checks the biomarkers that manage and influence the reproductive system of the body. It is a test that can be done in the comfort of your home using a finger-prick test kit. Once a sample has been collected, it is sent to our labs via a local post box and a doctor reviews your results to provide insight into your fertility.

    The biomarkers tested include:

    • Anti-Mullerian Hormone (AMH)
    • Follicle-Stimulating Hormone (FSH)
    • Luteinising Hormone (LH)
    • Prolactin
    • Thyroid-Stimulating Hormone (TSH)
    • Thyroxine (T4)
    • Triiodothyronine (T3)

  • What affects female fertility?

    Age is a direct factor in a woman’s fertility, with women being most fertile in their 20s and a natural decline in fertility during their 30s.

    However, there is a complex network of hormones at play within a woman’s body that are involved in reproduction and fertility and an imbalance of the four key sex hormones Follicle-Stimulating Hormone (FSH), Luteinising Hormone (LH), Oestradiol and Progesterone can result in fertility issues.

  • How can I naturally boost my fertility?

    Fertility in women can be heavily impacted by stress. Whilst stress is a natural reaction to life’s challenges, it can have a significant impact on your reproductive health.

    Chronic stress can have a disruptive effect on the balance of hormones that regulate ovulation, causing irregular menstrual cycles or even stopping them completely – known as amenorrhea.

    However, there are a number of lifestyle changes that can be implemented that can improve the balance of your key sex hormones, improving the regulation of your menstrual cycle and ovulation.

    Natural methods to manage stress and boost fertility can be found in our blog.

  • When does female fertility peak?

    A woman’s fertility normally peaks in their 20s.

  • When does female fertility decline?

    Usually, a woman’s fertility naturally begins to decline in their 30s.

  • How soon will the test arrive?

    If you order your test before midday on a Monday to Friday then your kit will be dispatched the same day. All our kits are sent out via Royal Mail first class post, so it should be with you within 1-2 working days.

  • Can I have someone take my blood for me?

    Yes. We offer two options if you do not want to do our finger prick test. The first is a home appointment where a nurse comes to your home to take a blood sample. The second is to visit a Phlebotomy clinic near you that offers a blood sample service.

    A blood sample will be taken from your vein and we will provide you with everything you need to give to the nurse to allow them to take the sample. The nurse will give you the blood sample to return to us using the pre-paid envelope provided.

  • Does a doctor review my results?

    We have a team of doctors and nurses who look at all results and will comment on any results that are outside of the normal range for your age.

  • Can I download the results to share with my GP?

    Yes, you can download your results from your health dashboard as a PDF to share with your GP.

About flexible subscriptions

How does a subscription work?

When you purchase this test subscription plan, we will automatically send you another test kit in a few months. Don’t worry – you have full control over when this will be, and you can change/cancel it anytime.

When you first purchase this test, you can choose your subscription options in the checkout. We do this, because we recommend taking multiple tests over time to track how your health markers change. You’ll be charged per test kit (rather than monthly, for example).

Why subscribe to multiple tests?

One test will show you what areas you need to focus on, continued testing will help you learn how your training, diet and lifestyle is impacting your health.

How often should I test?

We recommend a follow up test 3 months after your first test, followed by a test every 6 months depending on your results, but its up to you!

Can I change what’s tested in future tests?

Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.
