A truly fertile ovary never allows the basal FSH level to creep upward. In regards to the question at the beginning about menopause, FSH of 18 is not premenopausal. While younger women with high FSH levels will notice menopause earlier than the average age of 52, the FSH itself does not cause hot flashes directly. Another component of the testing on day is the estradiol or E2. High levels may occur. So the elevated estrogen is a warning that the ovarian reserve is decreased, even though the FSH may be normal.
However this is just an indicator and not a brick wall. Many patients with persistence have conceived using properly selected clinical management. Once ovarian stimulation has been done, the FSH test is of secondary importance. How may follicles developed? That is infinitely better as a predictor for the future than the FSH test. Consider the elevated FSH as a warning sign. For more information about these treatments, you may contact us here.

Most girls will get their first period sometime between the ages of 10 and 15, but it can happen as young as 8. Follicle stimulating hormone FSH is one of the most important hormones involved in the natural menstrual cycle as well as in pharmacological drug-induced stimulation of the ovaries.
It is the main hormone involved in producing mature eggs in the ovaries.. FSH is the same hormone that is contained in the injectable gonadotropins which are used to produce multiple eggs for infertility treatment. When a women goes into menopause she is running out of eggs in her ovaries. The brain senses that there is a low estrogen environment — and signals the pituitary to make more FSH hormone. More FSH is released from the pituitary in an attempt to stimulate the ovaries to produce a good follicle and estrogen hormone.
Think of it like stepping on the gas pedal in the car to get going. In a menopausal woman, the gas pedal is on the floor for the rest of her life — even though there are no follicles or eggs left.
As women approach menopause their baseline FSH levels day 3 of their cycle will tend to gradually increase over the years. When they run out of follicles capable of responding, their FSH will be high and they stop having periods. Therefore, if the baseline FSH is elevated the ovarian reserve how many eggs are left is reduced sometimes the egg quality is also reduced.
This is particularly true for women in their 40s. An infertile 44 year old woman with a normal FSH for example 6 still has a very low probability of conceiving and delivering a baby with in vitro fertilization — or with any other fertility treatment. The fact that she is 44 greatly diminishes her chances — even if her FSH is normal.
This is why IVF programs have age cutoffs. The oldest women accepted by IVF programs varies somewhat — most programs have a cutoff somewhere between age Infertile women older than 44 will very rarely be successful using their own eggs. However, these women are excellent candidates for in vitro fertilization with donor eggs. In our fertility center we currently use an assay made by Roche. We consider normal FSH level to be anything less than 9.
As levels go above 9 we often see a reduction in response to ovarian stimulating drugs — as described in the table below. If your FSH levels were run using a different assay, you can not compare your results to those shown below with confidence. These symptoms may be more severe than in women in natural menopause, and is considered atypical as it begins much earlier. About one percent of women have this condition. High FSH levels could also indicate poor ovarian reserve — also known as impaired ovarian reserve, premature ovarian aging, premature ovarian insufficiency, or declining ovarian reserve.
In this condition, you either have relatively few eggs left in the ovaries, or impaired development or recruitment of the eggs. Recent research suggests that this condition may be a precursor to premature ovarian failure. However, these are usually identified early in life, and are unlikely to be responsible for newly diagnosed high FSH levels.
