FSH (Follicle-Stimulating Hormone) – FSH is a pituitary hormone that drives egg development in women and sperm production in men.
What FSH measures
FSH measures reproductive signaling – useful in fertility assessment and evaluating menopause or testicular function.
Typical ranges
Values depend on sex and, for women, the menstrual-cycle day; labs provide phase-specific ranges. Reference ranges differ between laboratories and by age and sex, so always read your result against the range printed on your own report.
What high results can mean
In women, high FSH can indicate declining ovarian reserve or menopause; in men, it can point to testicular issues.
What low results can mean
Can reflect pituitary or hypothalamic problems.
How the test is done
A blood sample; women are often tested on cycle day 3. At-home collection works well for this marker when the sample is processed by a certified lab.
