A follicle-stimulating hormone test measures
the amount of follicle-stimulating
hormone (FSH) in a blood sample. FSH is produced by
- In women, FSH helps control the
menstrual cycle and the production of eggs by the
ovaries. The amount of FSH varies throughout a woman's
menstrual cycle and is highest just before she releases an egg
- In men, FSH helps control the production of sperm. The
amount of FSH in men normally remains constant.
The amounts of FSH and other hormones (luteinizing hormone,
estrogen, and progesterone) are measured in both a man and a woman to determine
why the couple can't become pregnant (infertility).
The FSH level can help determine whether male or female sex organs (testicles or ovaries) are functioning properly.
