Frequently asked questions​

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

  • Why test oestrogen levels?

    Oestrogen is one of the four sex hormones that drives key bodily functions, including the menstrual cycle; with abnormal levels causing a host of symptoms and long term conditions.

    It is very important that women understand how their 4 sex hormones are rising and falling during their monthly cycle as they intricately work together. Abnormal levels of oestrogen can be caused by a number of factors which can be identified with testing.

    Forth’s MyForm test uses proprietary AI technology to map your hormones during your cycle to give you a detailed view of how your hormones are fluctuating, with a detailed report of actions that can be taken to improve their levels.

  • What are the symptoms of low oestrogen?

    The symptoms of low oestrogen include:

    • hot flushes
    • changes in mood
    • decreased bone density
    • fatigue
    • sleep disorders
    • sexual dysfunction

    The reduction in oestrogen at the time of menopause has also been linked to the development of osteoporosis in postmenopausal women. A natural fall in oestrogen in men can cause osteoporosis in elderly men as well.

  • What does oestrogen do in the menstrual cycle?

    Oestrogen is one of the four sex hormones that rise and fall significantly during the menstrual cycle to regulate the release of an egg from the ovaries.

    During the Follicular Phase, a follicle in the ovary starts developing as it prepares to release an egg. This produces oestrogen, the main ovary response hormone during this phase, which peaks just before Ovulation.

    Oestrogen makes the lining of the uterus thicker and more receptive to a fertilised egg, and it can also increase libido which is your body’s way of driving reproduction.

  • How can I reduce my oestrogen levels?

    Oestrogen is an essential sex steroid hormone in the body, but too much of it can cause irregular periods and worsen your reproductive health.

    It is rare for high oestrogen to be caused by what your body is producing. Often medications such as hormonal contraceptives can lead to high levels of oestrogen, reducing libido as an example. In this case, you should speak to your GP about appropriate changes to your care plan.

    High oestrogen unrelated to medication can be caused by PCOS prior to menopause, and being overweight after menopause.

    In general, you should look out for:

    • being overweight (body fat tissues secrete oestrogen)
    • medications that raise oestrogen
    • stress increases cortisol, which can reduce progesterone levels. This allows oestrogen levels to go unchecked
    • liver health issues that can prevent the effective breakdown of oestrogen, allowing it to accumulate
    • drinking too much alcohol can reduce your body’s ability to breakdown oestrogen
    • potentially having polycystic ovary syndrome (PCOS), which can be checked with our PCOS test

  • How can I increase my oestrogen levels?

    Oestrogen levels can potentially be boosted naturally through the following methods:

    • Food – eating more sesame seeds, soybeans, and flax seeds
    • Supplements – taking Boron, DHEA, B vitamins, and vitamin D
    • Herbal supplements – taking chasteberry, red clover, dong quai, and black cohosh

    If you are experiencing the symptoms of perimenopause, it may be advisable to discuss HRTwith your GP as studies show that starting this treatment option early can reduce the risk of long term health conditions.

  • What is oestrogen?

    Oestrogen is a sex steroid hormone that has 3 forms in women: oestrodiol, oestrone, and oestriol. Oestrodiol is the strongest and main form of oestrogen in the body. Oestrogen will be at its highest levels during reproductive years and falls significantly during perimenopause.

    Oestrogen is produced mostly in the ovaries of women of reproductive age, with adrenal glands and body fat tissue also secreting oestrogen. It is one of the four sex hormones that rise and fall during the menstrual cycle to regulate the release of an egg from the ovaries. Oestrogen is responsible for feminine characteristics, but it is a hormone also found in men.

  • How soon will the test arrive?

  • 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.

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.
