How does the Perimenopause test determine if I am approaching menopause?

LH and FSH are the two hormones responsible for maturing an egg that ultimately is released in a process called ovulation. As egg quantity decreases with age, the levels of these hormones increase in response to the decreasing egg numbers. Elevated levels of LH and FSH can be seen several years before a woman actually enters menopause, and menopause is when a woman no longer has any viable eggs in her ovaries.
