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 doctor 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.
