What do your FSH levels mean?
The short answer
Nobody we follow has said what your FSH should be. It comes up on the shows, but never with a number.
Your lab prints 1.7–12.5 mIU/mL. That range exists to catch disease, not to describe your best.
Labs print different ranges by sex: about 1.7–12.5 mIU/mL for women and 1.5–12.4 for men.
What FSH measures
A pituitary hormone that tells the ovaries or testes to mature eggs or sperm.
It rises when the ovaries or testes stop responding. That makes it a fertility and menopause marker.
