Tests with LH, FSH, or oestradiol

If you're taking your test to learn more about your fertility, take your test between days 2 and 5 of your menstrual cycle, or ideally day 3. Otherwise, for a general health check or if you're postmenopausal, you can take your test at any time.

In either case, it's important to log the date of your last period, and any other information regarding your periods or menopause status, in your MyMedichecks account right after taking your sample.

If you don't let us know the date of your last period, we'll interpret your result as though you took your test on day 3.

What's in the test?

Hormones

FSH

Learn more

Follicle Stimulating Hormone (FSH) is produced in the pituitary gland and is important for women in the production of eggs by the ovaries and for men in the production of sperm. In the first half of the menstrual cycle in women, FSH stimulates the enlargement of follicles within the ovaries. Each of these follicles will help to increase oestradiol levels. One follicle will become dominant and will be released by the ovary (ovulation), after which follicle stimulating hormone levels drop during the second half of the menstrual cycle. In men, FSH acts on the seminiferous tubules of the testicles where they stimulate immature sperm cells to develop into mature sperm.

LH

Learn more

Luteinising Hormone (LH) is produced by the pituitary gland and is important for male and female fertility. In women it governs the menstrual cycle, peaking before ovulation. In men it stimulates the production of testosterone.

Oestradiol

Learn more

Oestradiol is the strongest of the three oestrogens. It's labelled a female hormone but it's made in both the ovaries and testes. It's responsible for the growth of breast tissue, the female reproductive system, and male sexual function.

In pre-menopausal women, oestradiol levels vary throughout the monthly cycle, peaking just before ovulation. Levels are lowest after menopause when the ovaries stop producing eggs. Low oestradiol levels in women can cause many symptoms associated with the menopause, including hot flushes, night sweats, and changes in mood. It can also increase the risk of osteoporosis (a condition where the bones become less dense).

In men, oestradiol levels tend to increase slightly with age as testosterone levels decline. Too much oestradiol in men can contribute to fertility problems, gynecomastia (enlarged breast tissue), and erectile dysfunction.

How to prepare for your test

Prepare for your Day 3 Fertility Blood Test by following these instructions. Take this test two to five days after the start of your period, ideally on day three. It can be taken any time if you do not have periods. Hormonal contraception can affect this test, taking a break from this and using barrier contraception will give more accurate results. If you use hormone gels, pessaries, patches, or tablets, we strongly recommend selecting a venous sample to minimise contamination sometimes seen with finger-prick tests. Otherwise, administer any hormone supplements using gloves, and make sure your fingers have not been in contact with hormone supplements for at least four weeks before taking the test. Hormones can be absorbed deep within the skin even after minimal contact and remain there for weeks despite vigorous handwashing. Do not take biotin supplements for two days before this test, discuss this with your doctor if it is prescribed.

Test limitations
While this test offers a useful snapshot of your fertility potential, it doesn’t provide a full picture or guarantee pregnancy. Abnormal results may indicate the need for further investigations or specialist advice to guide your next steps.

    FAQs

    What can I learn from this test?

    Our test includes Follicle-stimulating hormone (FSH), luteinising hormone (LH), and oestradiol. FSH is released from a gland in your brain (the pituitary gland) to stimulate the ovary to start maturing an egg. LH is required for the final maturation and release of the egg from a follicle (a fluid-filled sac containing the egg), while the hormone oestradiol stimulates the growth of the follicle and prepares the womb lining for pregnancy.

    The levels of hormones in your body on day three of your cycle can indicate whether hormonal problems are likely to affect ovulation and conception and whether a condition like polycystic ovaries may be affecting fertility.

    What could affect my results?

    Please note that any hormones you are taking for contraception or hormone replacement therapy (HRT) will influence your results. If you are looking for a true picture of your fertility status then please take this test at least 12 weeks after stopping any hormone replacement or contraceptive pill, implant or hormone IUD. It is recommended to wait until your periods have re-established a regular cycle (for you) before taking this test.

    What is a fertility blood test?

    Our day three fertility test is a helpful first test in an investigation into female infertility. Ideally, you should take our test three days after the start of your period, but it can also be taken on days two, four, or five of your menstrual cycle. This test aims to check that hormone levels can support the maturation and release of a healthy egg from the ovary.
