The Follicle Stimulating Hormone (FSH) test is a key blood test used in fertility evaluation. FSH is produced by the pituitary gland and plays a vital role in controlling the menstrual cycle and stimulating the growth of ovarian follicles, which release eggs during ovulation.
In women, FSH levels help assess ovarian reserve (the quality and quantity of eggs available). In men, FSH supports sperm production.
Doctors may recommend an FSH test in cases of:
* Difficulty conceiving (infertility)
* Irregular or absent menstrual cycles
* Suspected ovarian insufficiency or premature menopause
* Assessing ovarian reserve before IVF treatment
* Male infertility evaluation (low sperm count)
* A simple blood sample is taken, usually on day 2–5 of a woman’s menstrual cycle.
* The blood is tested in the lab to measure FSH hormone levels.
Results are interpreted in relation to age, menstrual cycle phase, and other fertility hormone levels (such as AMH, LH, and Estradiol).
The FSH test measures the level of Follicle Stimulating Hormone in the blood. It helps evaluate ovarian reserve in women, sperm production in men, and overall reproductive health.
For women, the FSH test is usually done on day 2–5 of the menstrual cycle for the most accurate assessment of ovarian reserve. Men can take the test on any day.
High FSH levels may indicate reduced ovarian reserve, perimenopause, menopause, or primary ovarian insufficiency. In men, it may suggest testicular dysfunction.
Low FSH levels can suggest a problem with the pituitary gland or hypothalamus, which control hormone release and ovulation.
No. While FSH is an important fertility marker, it is usually combined with other tests such as AMH (Anti-Müllerian Hormone), Estradiol levels, and Antral Follicle Count (AFC) for a complete fertility evaluation.
