Our ground-breaking female hormone test predicts how your four key female hormones fluctuate over your entire menstrual cycle rather than just a single day. Using the latest techniques in artificial intelligence, we combine blood analysis with medical expertise and mathematical modelling, to give you unparalleled scientific insight into your personal hormone health, with support and advice from Forth’s Chief Medical Officer and leading endocrinology expert, Dr Nicky Keay.
Every woman can expect to experience up to 480 unique monthly fluctuations in their female hormones over a menstrual cycle.
The levels of FSH, LH, Oestrogen and Progesterone rise and fall significantly in a complex but characteristic pattern over the course of each woman’s cycle. This hormone pattern is essential to female health. The length of cycle, the timing of ovulation and the levels of each hormone will all vary from one woman to another making each woman’s pattern unique.
Because no two women are the same, Female Hormone Mapping™ provides unique personalisation and unparalleled insight in your hormone network.
By combining medical grade laboratory blood analysis with clinical expertise and artificial intelligence, Female Hormone Mapping™ predicts how a woman’s four key hormones fluctuate throughout their entire cycle, which is entirely unique to you. It’s the next step in personalised female health intelligence.
You’ll get explanation, commentary and advice from Forth’s expert endocrinologist on:
Female Hormone Mapping™ is designed for all women who are experiencing natural menstrual cycles.
Hormones play a vital role in physical and mental health. Your female hormone variations are personal to you which is why it can be challenging to find answers that are relevant to you as an individual woman. Female Hormone Mapping™ provides you with individualised insights, personalised medical explanation and evidence-based advice

Hormones have far reaching effects on many systems in the female body beyond reproduction.
The four key fertility hormones also impact, the nervous system, the musculoskeletal system, the digestive system, the cardiovascular system, the immune system and metabolism. In short, female hormones are integral to a woman’s health & wellbeing.
A hormone imbalance can affect a woman’s mood, weight, energy levels as well as fertility.
By telling us how you are feeling across five key wellbeing metrics, we’ll help you understand the relationship between hormone variations and how you feel. You’ll also receive a personal action plan of what to do next to help improve your hormones and optimise your quality of life.
Find out if your ovarian responsiveness is declining.
Female Hormone Mapping™ is useful for women over 40 who want to know if the symptoms they are experiencing may be due to the perimenopause. In addition to identifying a drop in the ovarian hormones and a rise in the control hormones, which is characteristic of the perimenopause, we’ll also measure your ovarian responsiveness, through our unique FORM score.
FORM (Forth Ovarian Response Metric) evaluates how well your hormone network is functioning. Presented as a number between 1-100, this score can be used to chart the decline in ovarian responsiveness over time.
Gain insight into all four hormones essential to the female hormone network by testing on day 14 and day 21 of your cycle.
Progesterone is used to measure if a woman has ovulated. Levels start to raise following ovulation and is therefore more likely to affect how you feel in the second half of your cycle. Progesterone levels will start to decline over the age of 40.
Oestradiol is the main form of Oestrogen in women and levels peak just before ovulation. As oestradiol is the dominant in follicular phase, it is more likely to influence how a woman feels in the first half of their cycle. Oestradiol levels will start to decline when entering the perimenopause.
Follicular Stimulating Hormone is one of the two control hormones which control the production of progesterone and Oestradiol. FSH increases steadily during the first half of the cycle stimulating the development of the follicle prior to ovulation. FSH become consistently raised as women transition towards the menopause.
Luteinising Hormone works alongside FSH to control the production of Progesterone and Oestradiol. LH remain low for most of the cycle but surges sharply to trigger ovulation mid-cycle.
Here are some of the most frequently asked questions. If you need anything else try our help section.
Female Hormone Mapping™ measures the four key female hormones. These are Oestradiol (the main form of Oestrogen), Progesterone, Follicular Stimulating Hormone (FSH) and Luteinising Hormone (LH).
No, our algorithm will adjust your curves to the length of your personal cycle, so it is important that you collect your samples as close to day 14 and 21 as possible, even if you have a longer or shorter than average cycle.
If your day 14 or 21 falls on a Friday, we recommend you collect your sample the day before. If your day 14 or 21 falls over the weekend, collect your sample on the following Monday and remember to post in a priority post box in time for that day’s collection.
Follicular Stimulating Hormone (FSH) and Luteinising Hormone (LH) are known as the control hormones and are produced by the pituitary gland. These hormones control the production of the ovarian response hormones, Oestradiol and Progesterone.
Oestradiol (the main form of Oestrogen) and Progesterone are ovarian response hormones which are produced by the ovaries. Their production is stimulated by the control hormones FSH and LH. If the control hormones are low, then the ovarian response hormones are also likely to be low. The exception to this is in later life (over 40) when the control hormones start to rise as ovarian responsiveness starts to decline i.e. the transition towards the menopause.
The Forth Ovarian Response Metric (FORM) is a unique and innovative evaluation of the functioning of the hormone network. This score takes into account all your hormone results rather than looking at any one in isolation. A score above 75 suggests a healthy ovarian response. Women over 40 can expect to see a decline in their ovarian response score as they enter the perimenopause and approach the menopause.
Female hormones, particularly the response hormones, have far reaching effects on a woman’s wellbeing. They are essential not only to the reproductive system but also the nervous system, musculoskeletal system, the digestive system, the cardiovascular system, the immune system and metabolism (that’s quite a list!). So you can see why healthy hormones are important throughout a woman’s life not only when wanting to start a family. In addition, the rise and fall of the ovarian hormones progesterone and oestradiol can influence how you feel throughout your cycle. Understanding how your hormones fluctuate can therefore help you to put strategies in place so you can feel at your best throughout your cycle as well as protecting your long term health.
Hormones can be influenced by lifestyle behaviours such as sleep, stress, nutrition and exercise. That’s why we give you tips and an action plan based on your results of the things you can do to improve your hormone levels and your quality of life.
