Follicle-stimulating hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg and increases oestradiol production. What does all of this mean and how do people use it to test if they’re menopausal?
As a woman nears perimenopause, the amount of small follicles in each cycle diminishes, so theoretically, the level of FSH begins to rise. Some people would think that this is a sure way to test if you’re perimenopausal…
This can be misleading because FSH levels (and oestrogen) can vary greatly during perimenopause, so one high FSH level is not enough to confirm menopause (or the diminishing of the ovarian cycle). So really, it depends what kind of day you’re having, where you are in your cycle that determine your FSH level, more than whether or not you are menopausal.
