About the test
What is this test done for?
FSH is a test performed to assess blood levels of the hormone secreted from the pituitary gland.
Why is it Done?
FSH is a hormone that is important for reproduction and development of eggs in women and sperms in men. The test is done to determine the cause of infertility and assess pituitary or hypothalamus disorders.
When should it be performed?

The test should be performed if:

  • If there are menstrual irregularities.
  • In children, to detect early puberty when signs like breast enlargement or growth of pubic hair or in boys, growth of testicles and penis.
  • Women with infertility or difficulty in conceiving a child.

How is it done
A blood sample will be collected from a vein in your arm. Fasting is not needed for blood collection.
Results
The test is usually combined with other tests like LH and testosterone.
  • If FSH is beyond the normal level, it suggests primary ovarian failure in women. It could be positive in development defects, Turner’s syndrome or defect in steroid production in ovaries, like 17 alpha hydroxylase deficiency. It could be high in polycystic ovarian disease or diseases due to thyroid disorders. In men, development defects in gonads, also testicular failure in infections like mumps or germ cell tumours. It can be high due to use of certain medications like clomiphene, digitalis, levodopa.
  • FSH results can be below normal due to certain use of medications like contraceptives and other hormone medications, and in pregnancy.
Other Tests
