If you have periods

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?

Adrenal hormones

DHEA sulphate

Learn more

DHEAS is the sulphated form of DHEA, a hormone which is produced by the adrenal glands and is responsible for male characteristics in both men and women. DHEAS gradually declines from the age of 30 onwards.

Hormones

AMH

Learn more

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.

Testosterone

Learn more

Testosterone is a hormone that causes male characteristics. For men, it helps to regulate sex drive and has a role in controlling bone mass, fat distribution, muscle mass, strength and the production of red blood cells and sperm. Testosterone is produced in the testicles of men and, in much smaller amounts, in the ovaries of women. Testosterone levels in men naturally decline after the age of 30, although lower than normal levels can occur at any age and can cause low libido, erectile dysfunction, difficulty in gaining and maintaining muscle mass and lack of energy. Although women have much lower amounts of testosterone than men, it is important for much the same reasons, playing a role in libido, the distribution of muscle and fat and the formation of red blood cells. All laboratories will slightly differ in the reference ranges they apply because they are based on the population they are testing. The normal range is set so that 95% of men will fall into it. For greater consistency, we use the guidance from the British Society for Sexual Medicine (BSSM) which advises that low testosterone can be diagnosed when testosterone is consistently below the reference range, and that levels below 12 nmol/L could also be considered low, especially in men who also report symptoms of low testosterone or who have low levels of free testosterone.

Free androgen index

Learn more

The free androgen index (FAI) is a calculation used to determine the amount of testosterone which is free (unbound) in the bloodstream. Most testosterone is bound to proteins sex hormone binding globulin and albumin and is not available to interact with the body's cells. The FAI is a calculation based on the ratio of testosterone and SHBG and is a measure of the amount of testosterone that is available to act on the body's tissues. The free androgen index is used in women to assess the likelihood of polycystic ovarian syndrome. In men, free testosterone gives a better indication of testosterone status.

Prolactin

Learn more

Prolactin is a hormone which is produced in the pituitary gland and plays a role in reproductive health. Its primary purpose is to stimulate milk production after childbirth, and in pregnant and breastfeeding women prolactin levels can soar.

Proteins

SHBG

Learn more

SHBG (sex hormone binding globulin) is a protein which transports the sex hormones (testosterone, oestrogen and dihydrotestosterone (DHT)) in the blood.Hormones which are bound to SHBG are inactive which means that they are unavailable to your cells. Measuring the level of SHBG in your blood gives important information about your levels of free or unbound hormones which are biologically active and available for use.

Thyroid hormones

TSH

Learn more

Thyroid stimulating hormone (TSH) is produced in the pituitary gland in order to regulate the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3) by the thyroid gland. If thyroid hormones in the blood are low, then more TSH is produced to stimulate the thyroid gland to produce more of them. If thyroid hormone levels are high, then the pituitary produces less TSH to slow the production of thyroid hormones. If TSH is too high or too low, it normally signifies that there is a problem with the thyroid gland which is causing it to under or over produce thyroid hormones. Sometimes a disorder of the pituitary gland can also cause abnormal TSH levels.

Free T3

Learn more

Triiodothyronine (T3) is the more active of the two thyroid hormones produced by the thyroid gland. Most T3 is bound to protein in the blood. Free T3 measures the level of T3 that is free, or unbound to protein, and is available to regulate metabolism.

Free thyroxine

Learn more

Thyroxine (T4) is one of two hormones produced by the thyroid gland. It works to speed up the rate of your metabolism. Most T4 is bound to carrier proteins in the blood - it is only the free, or unbound, T4 that is active in the body, which is measured in this test. Free T4 is the less active of the two main thyroid hormones. To have an impact on your cells it needs to convert to the more active T3 when your body needs it.

How to prepare for your test

Test limitations

While this test provides valuable insights about your hormone health, it can’t diagnose specific conditions or directly assess whether you are fertile. Fertility is complex and depends on many factors, including sperm health, egg quality, and lifestyle factors.

LH, FSH, and oestradiol levels will be interpreted assuming your sample was taken between days two and five of your menstrual cycle, unless you let us know otherwise. You can tell us which stage of your cycle you were in by adding your LMP (date of last menstrual period) into the supporting information in your MyMedichecks account. Here, you can also add extra information about your periods, including whether they are irregular or absent.

    FAQs

    Which test is best for female fertility?

    There isn’t a single best test to assess fertility – each one provides unique insights into different aspects of your reproductive health.

    For example, AMH and FSH can give insights into your remaining egg count, whereas LH and oestradiol can help assess your menstrual cycle and ovarian function.

    Which day of my cycle should I take my test?

    This test can be taken between days two and five of your menstrual cycle, but day three is ideal. . This is when levels of LH, FSH, and oestradiol are at their lowest and most stable.

    If your periods are irregular, aim to test on day three of your next period. If this isn’t possible, or you don’t have periods, you can collect your sample on any day of the cycle. Just make sure you let us know in the supporting information so we can interpret your results as accurately as possible.

    It’s best to take your test in the morning as some hormones fluctuate throughout the day.

    How do I know if I’m fertile?

    Positive signs of fertility include having regular menstrual cycles, healthy hormone levels, and monthly changes in cervical mucus, indicating ovulation. However, these aren’t requirements for fertility, nor can they prove you are fertile. The only way to be certain you are fertile is by becoming pregnant.

    Blood tests and other investigations, like scans, can help identify issues that may affect your fertility, but in some cases, the cause of infertility isn’t found.

    Can I check my fertility if I’m taking hormonal contraception?

    Yes, you can still take a test while you’re taking hormonal contraception, but some biomarker results might be affected, i.e. LH, FSH, oestradiol, and AMH. For more accurate results, you may wish to switch to barrier methods of contraception (condoms) and wait for your periods to return to normal before testing.

    If you’re unable to stop taking your hormonal contraception, please let our doctors know in the supporting information so they can account for this when interpreting your result.

    The remaining biomarkers in this test aren’t significantly affected by hormonal contraception.

    Can I take the test if I have polycystic ovary syndrome (PCOS)?
    Yes, you can still take our fertility test if you have PCOS. However, your AMH result is likely to be falsely raised due to the higher number of follicles in the ovaries. This means your egg count may appear higher than it actually is.

    What are the most important hormones for fertility?
    Several hormones play an important role in fertility by regulating the menstrual cycle and ovulation. These include FSH, LH, oestradiol, testosterone, progesterone, prolactin, DHEA-S, and AMH. Healthy thyroid hormone levels are also important for cycle regularity and ovulation.

    What should my hormone levels be for fertility?

    The ideal hormone levels for fertility can vary and each laboratory provides a different reference range. The table below is given as a guide only.
