Hormones
FSH
LOINC 10501-5 · UI/L
What it is
FSH (follicle-stimulating hormone) is made by the pituitary gland to control the ovaries and testicles and support reproduction.
Why it matters
It helps assess fertility, the menstrual cycle and where someone is in the reproductive life stage, such as menopause.
What high values can mean
A higher value can reflect reduced ovarian or testicular activity, or a natural transition such as menopause.
What low values can mean
A lower value may relate to a pituitary or hypothalamic issue affecting hormone signalling.
How to improve it
FSH reflects reproductive physiology and is not changed by lifestyle; interpretation depends on your context.
Food & lifestyle
No specific food changes FSH; general healthy habits support overall reproductive health.
Preparing for the test
Timing matters in menstruating women — note your cycle day; follow your lab's instructions.
When to talk to a doctor
Discuss abnormal FSH with a doctor for fertility concerns, irregular cycles or menopause questions.
