FAQs

What is oestradiol?
Oestradiol (E2) is the main form of estrogen, a hormone that plays a key role in reproductive and overall health. It’s produced mainly by the ovaries in women and in smaller amounts by the adrenal glands and testes in men.
Why is oestradiol important?
In women, oestradiol regulates the menstrual cycle, supports fertility, maintains bone density, skin, mood, and cardiovascular health. In men, it contributes to bone health, libido, and sperm production (in balance with testosterone).
When should I take a female hormone test?
Testing female hormone levels is best between days two and five of your menstrual cycle, with day three being ideal. At this stage, levels of luteinising hormone (LH), follicle-stimulating hormone (FSH), and oestradiol are typically at their lowest and most stable. If your periods are irregular, aim to take the test on day three of your next cycle. If that is not possible, or if you do not have periods, you can take the test on any day, but please let us know the date your sample was collected, so we can interpret your results accurately. For the most reliable results, we recommend taking your sample in the morning, as hormone levels can fluctuate throughout the day.
