FSH Test: What It Shows and What It Does Not
Quick answer: Follicle stimulating hormone is made by the pituitary gland. In women it helps control the menstrual cycle and egg development. An FSH test is used to look at menopause, fertility and period changes.
About this test
The test measures FSH in your blood. In women it helps eggs mature. In men it supports sperm production.
Why is it ordered?
- Irregular periods or missed periods.
- Looking at perimenopause and menopause symptoms.
- Fertility questions in women and men.
- Looking at pituitary or ovarian function.
What results may show
- A higher level can go along with menopause or reduced ovarian function.
- In men, a higher level can go along with testicular problems.
- A lower level can point to a pituitary or hypothalamus issue.
What this test may not show
- FSH swings through the cycle and from month to month in perimenopause, so one result cannot confirm menopause.
- It does not show the cause of infertility.
- Hormone treatment and birth control can change results.
- It is read with LH, estradiol and your history.
How to prepare
- Timing in your cycle may matter. Your provider may ask for a specific day.
- Tell your provider about hormonal medicines.

Frequently asked questions
Can FSH confirm menopause?
Not by itself. Levels vary in perimenopause, and menopause is confirmed after 12 months without a period.
Do men get FSH tested?
Yes, as part of looking at fertility and testicular function.
Why is FSH tested with LH?
The two hormones work together, and the pattern gives more information than either one.
