Synonyms
FSH, pituitary gonadotropin
Purpose
The Follicle-Stimulating Hormone (FSH) Test measures the level of FSH in your blood. FSH is a hormone produced by the pituitary gland that plays a critical role in reproductive health. In women, FSH helps control the menstrual cycle and egg production; in men, it supports sperm production.
This test is important for evaluating fertility issues, menstrual irregularities, menopause, and conditions affecting the ovaries or testicles. It can also help diagnose disorders of the pituitary gland.
For a more comprehensive hormonal profile, doctors often order the FSH test alongside the Luteinizing Hormone (LH) Test and the Estradiol Test. Together, these tests offer deeper insight into reproductive function, hormone imbalances, and potential underlying conditions.
Patient Preparation
The patient should avoid taking biotin supplements for at least 72 hours before sample collection.
Samples
1ml with a minimum volume of 0.7ml of serum or plasma collected in a Gel-barrier, red-top, or green top tube (lithium heparin). Avoid using EDTA, oxalate, or citrate plasma. Transfer the separated serum to a plastic transport tube if a red-top tube is used. Store the sample at room temperature.
Reference Range
Children 8-30 days; <0.2-22.2mIU/ml,1-16years:0.2-17.0mIU/ml, adult male:1.5-12.4mIU/ml, female 1.7-21.5mIU/ml,postmenopausal:25.8-134.8mIU/ml
Results Turnaround
Within 24 hours after sample collection.
Diseases / Diagnostic indicators
FSH levels help assess how well the reproductive system and pituitary gland are working. Here’s what different results may suggest:
- High FSH levels may indicate:
- Menopause in women
- Gonadal failure (when the ovaries or testes aren’t functioning properly)
- Klinefelter syndrome in men (a genetic condition affecting male development)
- Anorchia (absence of testes)
- Castration or damage to reproductive organs
- Chronic alcoholism, which may disrupt hormone balance
- Low FSH levels may point to:
- Pituitary gland problems (which affect hormone production)
- Hypothalamic disorders, which impact the signals that trigger FSH release
Doctors usually interpret FSH results along with other hormone tests to get a clearer picture of what’s happening in the body.
