How can a fertility insights blood test help you?
This test gives you valuable insights if you’re considering family planning now or in the future. You can also see if your egg count is in the normal range for your age.
It also shows if you have a condition that might affect your fertility — like a thyroid condition. It won't tell you how likely you are to get pregnant or if you're infertile. This test needs to be taken on Day 3 of your cycle
Fertility can be affected by:
- long periods of stress
- polycystic ovary syndrome (PCOS)
- irregular periods
- being underweight or overweight
With a GP report and tailored advice for your body, you'll have the support to start planning for the future.
What's included in this blood test?
Luteinising hormone (LH)
Learn more
Mid-cycle, your LH levels increase so you can ovulate. If your LH levels are imbalanced, you might have irregular periods and have trouble getting pregnant. High LH levels can indicate menopause or PCOS.
Follicle-stimulating hormone (FSH)
Learn more
FSH stimulates your ovaries to produce oestradiol. FSH and oestradiol work together to grow and develop the eggs in your ovaries — so when you ovulate the egg is ready to be fertilised by sperm.
Oestrogen (oestradiol)
Learn more
Oestradiol (E2) is essential for regulating your menstrual cycle and ovulation. It also plays a key role in building up the lining of your uterus — allows for a fertilised egg to become implanted if pregnant.
Testosterone
Learn more
Testosterone is essential for your sex drive, bone and muscle health, mood, and cognitive function. Your levels gradually drop as you age. If your levels are out of range you might feel tired, have a low sex drive, and have low mood.
Thyroid function
Learn more
An underactive thyroid can affect your menstrual cycle and ovulation. If you have a thyroid condition, it can increase your risk of pregnancy complications — like a miscarriage. But with treatment, these issues can be reversed.
Anti-Müllerian hormone (AMH)
Learn more
AMH is a hormone released by cells in your developing egg sacs (ovarian follicles). Testing your AMH levels can help determine the number of eggs you have left — your ovarian reserve.
Prolactin
Learn more
Prolactin is a hormone made by the pituitary gland. It helps stimulate milk production during breastfeeding and helps to regulate your menstrual cycle. High levels can prevent ovulation.
When should you do this test?
The best time to do this test is on day 3 of your cycle (day 1 is your first day of bleeding) — this is when your results can be accurately interpreted.
If you have irregular periods
We recommend waiting until you have a period to get the most useful insights from this test.
If you have irregular periods combined with symptoms like acne, excess body hair (hirsutism), or weight gain, our PCOS blood test might give you better insights.
If you have no periods
You can do this test anytime, but it might be harder for our doctors to interpret your results.

Advice before doing this test
Why this test can't tell you about infertility
Infertility is the inability to get pregnant after one year of regular unprotected sex.
Because fertility is complex, we can’t measure all its contributing factors in a single blood test.
Other factors affecting fertility include fallopian tube damage or endometriosis, which can’t be detected in a blood test.
It’s important to know that many factors affecting fertility can be reversed or treated.

When should you do this blood test?
You should aim to do this test on day 3 of your period. This is when your reproductive hormone levels are easiest to interpret, giving you the best insights into your cycle.
If you don't have periods
You can do this test any time, but it might be harder for our doctors to interpret your follicle-stimulating hormone (FSH), luteinising hormone (LH), and oestradiol results.
If you have irregular periods
We recommend waiting until you have a period to get the most valuable insights from this test. Test on day 3 of your next cycle.
If you're on hormonal contraception
Your results might be harder to interpret if you take the contraceptive pill, injections, or have an implant. This doesn’t apply to the hormonal coil.
If you just stopped hormonal contraception
Wait 3 months before doing this test — this allows time for your natural cycle to return. If you were using the contraceptive injection, we recommended waiting a year.
If you use an oestrogen or testosterone cream/gel
If you use a topical oestrogen-containing or testosterone-containing cream or gel, always use a glove when applying it. Contact with your fingers could affect your testosterone result.
If you're breastfeeding
Breastfeeding can affect your hormone levels — which can make it difficult to accurately interpret your results. We recommend waiting until you've stopped breastfeeding before doing this test.
If you're pregnant
Don’t do this test if you're pregnant, as we won't be able to interpret your results.
