Follicle Stimulating Hormone (FSH)
What It Is
FSH is a hormone produced by the pituitary gland that stimulates the growth of ovarian follicles in women and sperm production in men.
Why It Matters
FSH levels help assess fertility, menstrual irregularities, and menopausal status.
If Levels Are High
Elevated FSH in women may indicate menopause or diminished ovarian reserve. In men, it may suggest testicular dysfunction.
If Levels Are Low
Low FSH may indicate pituitary dysfunction or be suppressed by certain medications.
Preparation
Women: best measured on day 2–5 of the menstrual cycle unless advised otherwise.
How Often to Test
As clinically indicated for fertility or hormonal assessment.
