Blood test
Female Hormone Test
Female hormone tests measure hormones such as FSH, LH and oestrogen. They help investigate periods, fertility, menopause and conditions like polycystic ovary syndrome.
Quick answer
Female Hormone Test: what it is and what the results mean
These blood tests measure reproductive hormones — including follicle-stimulating hormone (FSH), luteinising hormone (LH), oestrogen (oestradiol) and sometimes others — that control the menstrual cycle and fertility.
- Why it is done: They are used to investigate irregular or absent periods, fertility problems, symptoms of menopause, and conditions such as polycystic ovary syndrome, often alongside other tests.
- Understanding results: Patterns of hormones help build a picture — for example, a rise in FSH can support the menopause, while particular patterns may suggest polycystic ovary syndrome.
What it is
These blood tests measure reproductive hormones — including follicle-stimulating hormone (FSH), luteinising hormone (LH), oestrogen (oestradiol) and sometimes others — that control the menstrual cycle and fertility.
Why it is done
They are used to investigate irregular or absent periods, fertility problems, symptoms of menopause, and conditions such as polycystic ovary syndrome, often alongside other tests.
What to expect
Timing is important because hormones change through the menstrual cycle, so the test is often taken on a specific day of the cycle. It is a standard blood test from the arm and may be repeated.
Understanding the results
Patterns of hormones help build a picture — for example, a rise in FSH can support the menopause, while particular patterns may suggest polycystic ovary syndrome. Results are always read alongside the cycle day, symptoms and other tests.
Good to know
Risks and limitations
The blood test is very safe. Because hormones fluctuate across the cycle, correct timing is essential and a single result rarely gives the whole answer, so tests are interpreted together.

Answers
Female Hormone Test: frequently asked questions
When in my cycle should hormones be tested?
It depends on which hormones and why — some are best measured early in the cycle, others at a specific point. Your clinician will tell you which day to attend so the result is meaningful.
Can a blood test confirm menopause?
In some situations a raised FSH supports the menopause, but for many women it is diagnosed from symptoms and pattern of periods rather than a blood test. Results are interpreted with your age and symptoms.
