Interpreting FSH results
- In women, increased levels of LH and FSH are seen in primary ovarian failure which may be due to any chromosomal abnormality, exposure to chemotherapy, radiation therapy, polycystic ovarian disease, thyroid disease
- In men, high FSH levels indicate primary testicular failure which may be due to chromosomal abnormality, viral infection, chemotherapy or radiotherapy
- Low levels of LH and FSH are seen in secondary ovarian or testicular failure and indicate a problem with pituitary or hypothalamus
- In young children, high levels of LH and FSH with the development of secondary sexual characteristics at an unusually young age indicates precocious puberty which is usually due to problem with the central nervous system
