FSH levels in women change throughout the menstrual cycle, with the highest levels happening just before an egg is released by the ovary. This is known as ovulation. 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. What is it used for? In women, these tests are most often used to: Help find the cause of infertility Find out if there is a problem with ovarian function Find the reason for irregular or stopped menstrual periods Confirm the start of menopause , or perimenopause. Menopause is the time in a woman's life when her menstrual periods have stopped and she can't become pregnant anymore.
It usually starts when a woman is around 50 years old. Perimenopause is the transition period before menopause. Sometimes testing is done to check specific hormone levels, especially to evaluate fertility problems or when periods stop at an early age. This can help women make decisions about beginning or adjusting treatment. For some women, it may make sense to test for other causes of symptoms that can mimic perimenopause, such as thyroid disease.
Salivary hormone level tests are expensive, are not accurate, and should not be used to evaluate or treat menopause symptoms. Sometimes, elevated follicle-stimulating hormone FSH levels are measured to confirm menopause. However, a single FSH level can be misleading in perimenopause because estrogen production does not fall at a steady rate from day to day.
Instead, both estrogen and FSH levels can vary greatly during perimenopause. One elevated FSH level is not enough to confirm menopause. More important, a low FSH level in a woman who is having hot flashes and changing periods does not eliminate the likelihood that she is still in perimenopause.
