This is the first in a series of posts during which I will give you accurate and factual information in relation to female fertility blood tests. A huge number of blood tests can be performed to identify female fertility levels.
Most people (and I include some medical professionals in this) don't seem to appreciate that there is a specific science behind female fertility blood tests. There are specific female blood tests that, when performed correctly, will give you an insight into your fertility level. When performed incorrectly (i.e on the wrong day of your cycle) they tell you absolutely nothing. They are irrelevant and I can't stress this enough!
Trying to conceive is difficult enough without adding more confusion into the situation. Hopefully, you can trust your GP to perform your fertility blood tests correctly. I have lost count of the number of women who have told me their fertility bloods were 'normal' only to discover that they were taken on the wrong day of the cycle. This is so frustrating as it often means that months of wasted cycles have gone by which were filled with false hope.
FACT: Specific Female Fertility Blood Tests are accurate on Day 2, Day 3 or Day 4 of the menstrual cycle.
Day 1 of the menstrual cycle is the first full day of bleeding (spotting is not counted). The female cycle is controlled by hormones. Female fertility blood tests are simply monitoring the levels of these hormones in your body at a particular time in your cycle. On Day 2, 3 or 4 of the cycle the critical hormones that should be checked are FSH, LH and E2. All of these hormones should be at their lowest levels at this point in the cycle.
Take a look at this graph. Follow the individual increases and decreases of each hormone over the menstrual cycle.
FSH (Follicle Stimulating Hormone)
One of the most important hormones involved in menstrual cycle. Produced by the Pituitary gland it is involved in stimulating the development of mature eggs in the ovaries. As you can see from the graph it starts out at a low-level during the first three days of the female cycle. This is exactly the time you need to have an FSH blood test taken. FSH is like stepping on the accelerator in a car to get it moving. The more FSH you require to get a follicle 'going' at the start of the cycle the poorer your fertility level.
LH (Leutinising Hormone)
Produced by the pituitary gland, LH works alongside FSH at the start of the female cycle. Normal LH and FSH levels are at similar levels on Day 2, Day 3 or Day 4 of the menstrual cycle.
At the start of the menstrual cycle Estrogen levels should be low. Estrogen levels gradually rise as the follicle begins to grow.
If you are looking for an accurate reflection of your fertility level wait until the start of your next cycle. Have these blood tests performed on Day 2, Day 3 or Day 4.
