Day 3 Fertility Check Blood Test
About this test – Why take this test?
- You are planning to have a baby and you want to check your hormone status
- You are struggling to conceive and you want to check your fertility
- You want a general check of your reproductive hormones
This day 3 fertility test is normally the first test that is performed in any investigation into female infertility. It is performed 3 days after the start of your period (but it can also be taken on day 2 ,4 or 5) during the follicular stage of the menstrual cycle. The aim of the test is to check that hormone levels can support the maturation and release of a healthy egg from the ovary.
Follicle-stimulating hormone (FSH) is released from the pituitary gland to stimulate the ovary to start maturing an egg. Luteinising hormone (LH) is required for the final maturation and release of the egg from a follicle, while oestradiol both stimulates the growth of the follicle and prepares the uterine lining for a pregnancy.
The levels of hormones in the body on day 3 can indicate whether hormonal problems are likely to affect ovulation and conception, and whether a condition like polycystic ovaries may be affecting fertility. Our doctors will interpret your hormone check and advise you whether you need to see your doctor or specialist for further investigation.
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. We suggest waiting until your periods have re-established a regular cycle (for you) before taking this test.
Oestradiol is a female steroid hormone which is produced in the ovaries of women and to a much lesser extent in the testes of men. It is responsible for the female reproductive system as well as the growth of breast tissue and bone thickness. Oestradiol levels decline with age, culminating in the menopause when the ovaries stop producing eggs.
Raised oestradiol in women can cause acne, constipation, loss of sex drive and depression as well as raising the risk of uterine and breast cancer.
Oestradiol can also be raised in men due to excess fat (which produces oestradiol) or in relation to testosterone levels which have declined with age. Raised oestradiol in men can cause the growth of breast tissue, the loss of libido and infertility.
Low levels of oestradiol in women can lead to osteoporosis, problems with the menstrual cycle and fertility as well as fatigue and depression.
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.
Follicle Stimulating Hormone 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.
