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) Oestradiol (Oestrogen) 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.

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.

The nurse will give you the blood sample to return to us using the pre-paid envelope provided.

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.

"A female fertility blood test provides critical insights into your reproductive health. It assesses hormone levels related to ovarian function, egg reserve, and menstrual cycle regularity. This information can help you plan for pregnancy, identify potential fertility issues early, and explore appropriate interventions, increasing the chances of successful conception and family planning."

We’re changing people’s lives

I really like Forth and you probably saved my life because your lab discovered my critically low cortisol which was subsequently diagnosed as adrenal insufficiency by a hospital endocrinologist.

Maria

I find Forth professional and forward-thinking with a bigger range of tests than more traditional healthcare providers in the UK. I think it is closer to what you can get from US providers.

Richard C

I wanted to get more information about my own health instead of using the NHS who just test for a specific reason. I also wanted better historical data to view changes over time as the NHS systems aren’t very good for that.

James W

Finding out what is going on inside your body is key, especially now that the NHS is in crisis. If we can take control of our wellness (and flag up potential problems early) that has got to be a good thing.

Vannesa C

I am very satisfied with your excellent service and I have recommended you to all my friends who are also very interested in your products.
