Why do normal fluctuations of FSH occur?
Normal fluctuations occur as a result of puberty, the menstrual cycle, pregnancy, and menopause.
How do blood tests diagnose premature menopause?
Blood tests measure the levels of follicle stimulating hormone (FSH) and luteinizing hormone (LH). The levels of these hormones will be higher if menopause has occurred.
What are normal menopausal FSH and LH levels?
For a premenopausal woman, normal values range from 4-30 U/L or 5-20 micro-international units per milliliter. In a pregnant woman, FSH levels are too low to measure. After menopause, normal values range from 40-250 U/L
FSH result of 20.66 what does this mean?
Usually high FSH levels mean your ovaries are working hard and there are not many eggs left. It may also signal early menopause (depending on age).
What does high FSH levels mean in post menopausal women with hairloss?
High FSH levels are normal in a post menopausal women and can't be used to diagnose hair loss.
How long after last menses is it safe to stop using birth control?
12 full cycles with no period it is considered "safe" - You can also ask your doctor to check your follicle-stimulating hormone (FSH) and estrogen (estradiol) levels with a blood test. As menopause occurs, FSH levels increase and estradiol levels decrease.
If you are 45 had a blood test with a high FSH and the doctor said you are in menopause can you still get pregnant?
If you are in menopause you wont get pregnant.
Is it true that the levels of FSH and LH increase during lactation?
No, this is not true. FSH starts to suppress during pregnancy. LH remains low throughout lactation, but begins to rise again during weaning.
What does fsh level of 14.8 mean?
FSH, follicle stimulating hormone, is a hormone that regulates the formation of follicles (eggs) and estrogen and menstruation. The test may have been sent to tell what stage of the menstrual cycle you are in. It is most often sent to test for menopause. The level of 14.8 is normal for just about all of the menstrual cycle and does not support a diagnosis of menopause, although often the hot flashes and symptoms start before the FSH rises.
What does medical service code 83001 stand for?
It sounds like a test for menopause: http://www.womentowomen.com/menopause/fshtests.aspx?id=2&campaignno=menopause&adgroup=ag6menotest&keywords=fsh+level
Why the blood of post-menopausal women contains high level of FSH?
Follicle stimulating hormone (FSH) is the signal the brain sends to the ovaries to tell them to make more estrigen. As the ovaries lose th eability to make estrogen during menopause the brains senses this and so sends a stronger signal to make more and so releases more FSH.
What causes the peak in luteinizing hormone?
In the beginning of the menstrual cycle, LH and FSH stimulate the ovaries to make estrogen. During this time, there is a negative feedback loop, so levels of all three hormones are rather low. Eventually, as the estrogen levels slowly creep up, there comes a time when it switches from negative feedback to positive feedback (not exactly sure what the biochemical basis of this is), and LH and FSH levels skyrocket (estrogen levels go up to, but not as sharply, and there is always more LH than FSH). The LH surge causes ovulaton. The corpus luteum starts secreting progesterone, which inhibits LH and FSH secretion in a negative feedback manner, and so FSH and LH levels drop sharply.
