Follicle-Stimulating Hormone

FSH (Follicle-Stimulating Hormone) Test

What Affects the Test

Results of the follicle-stimulating hormone (FSH) test may be affected by:

• The use of hormones, such as testosterone, estrogen, and progesterone (including birth control pills).
• Heavy cigarette smoking.
• Age.
• The use of medicines, such as cimetidine, clomiphene, digitalis, and levodopa. Make sure your health professional has a complete list of all the prescription and over-the-counter medicines you are taking, including herbs and natural substances.
• Having a test such as a thyroid scan or bone scan that uses a radioactive substance within 1 week of the FSH test.
