In men, FSH helps control the production of sperm.

Normally, FSH levels in men do not change very much. In children, FSH levels are usually low until puberty , when levels begin to rise. In girls, it helps signal the ovaries to make estrogen. In boys, it helps signal the testes to make testosterone. Other names: follitropin, FSH, follicle-stimulating hormone: serum.

There is, however, debate in the medical community about saliva testing — with some claiming that the blood levels serum testing are the gold standard and others advocating for the validity of saliva tests. With salivary testing, your doctor takes samples of your saliva to see the levels of hormones you are producing and to determine if you have any deficiencies.

In some cases, your doctor may perform high resolution ovarian ultrasound to view your ovaries. This will determine whether you still have any eggs and follicles.

Studies have indicated that perhaps up to two-thirds of women diagnosed with premature ovarian failure POF do indeed have remaining follicles. The problem is, even when eggs are detected, attempts to stimulate ovulation through hormones have been relatively unsuccessful. However, ultrasound may make sense if you are in the early stages of premature menopause and are intending to pursue an aggressive fertility program.

However, before moving forward with your life you need a proper diagnosis, which can only be reached in consultation with your doctor.

When your ovaries begin to fail, your circulating estradiol levels fall. After ovulation, the empty follicle that once contained the egg produces the hormone progesterone to support conception, implantation and the early stages of pregnancy.

The high levels of progesterone prevent the release of more FSH from the pituitary gland. The empty follicle breaks down if no embryo implants into the lining of the uterus. This causes a drop in progesterone which allows for FSH production to start again at the beginning of the next menstrual cycle 5. Your menstrual cycle starts again with your next period, which is triggered by the drop in your estradiol and progesterone levels. The drop in these hormones is sensed by the hypothalamus in the brain which begins to produce gonadotropin-releasing hormone GnRH , which travels to the pituitary to produce FSH and LH.

These are then released into the bloodstream and FSH then acts on the ovaries to grow the follicles containing your eggs 1. Is this starting to sound familiar? A high FSH level can mean a number of things. When the number of immature follicles remaining in the ovary is small, we produce more FSH in order to successfully mature an egg each month for ovulation. In women under 40, a high FSH level can mean primary ovarian insufficiency POI , which is the loss of ovarian function before the age of 40 6,7.

High FSH levels are also seen in people with Turner syndrome, a genetic disorder that affects sexual development 8. For some people, high FSH levels can also indicate ovarian cancer, though this is very rare 9. Sometimes, FSH levels can be elevated due to dietary and lifestyle factors and therefore modifications in these areas may reduce them. However, it is important to understand that if high FSH levels have been caused by menopause, modifications to your diet or lifestyle will not be able to reverse this.

Dietary and lifestyle factors that can cause or contribute to elevated FSH levels include:. Low FSH levels can mean your ovaries are not maturing enough eggs or that your pituitary gland which releases FSH is not working correctly.
