FSH Blood Test in New Hampshire

An FSH blood test measures follicle-stimulating hormone, a hormone made by the pituitary gland that helps control the menstrual cycle in women and sperm production in men. It is often ordered to check fertility, investigate irregular periods or menopause, or evaluate pituitary function.

What it measures

FSH (follicle-stimulating hormone) — The main hormone measured; levels change with age, sex, and menstrual cycle timing.
Estradiol — Often tested alongside FSH in women to help interpret results.
LH (luteinizing hormone) — Sometimes added because it works with FSH in the reproductive system.
Testosterone — May be checked in men when low sperm production or low sex drive is evaluated.
Prolactin — Occasionally included to rule out other causes of hormone-related symptoms.

Who it is for

A doctor, fertility specialist, or endocrinologist typically orders this test. It may be requested for people with irregular periods, suspected menopause, fertility concerns, or symptoms of pituitary problems.

Preparation

No fasting is usually required. For women, the timing of the test may matter because FSH changes during the menstrual cycle, so follow your clinician's instructions about which day to test.

Results and what they mean

Results are reported as a number in international units per liter (IU/L), often with a reference range that varies by age, sex, and cycle day. A clinician interprets the number alongside your symptoms and other tests; it is not a diagnosis on its own. This is general information only and not medical advice.

Frequently asked questions

Do I need to fast for an FSH test?

No, fasting is not normally needed. A blood sample is taken, usually from a vein in your arm.

When in my cycle should I have the test?

Your clinician may ask you to test on a specific day, often early in the cycle. Follow those instructions for the most useful result.

Can FSH tell me if I am in menopause?

FSH is one piece of information. Menopause is usually confirmed by symptoms, cycle history, and sometimes more than one hormone test.

How long do results take?

Most FSH results are ready within 1 to 3 business days, though timing can vary by lab.
