The reasons why you may have elevated FSH hormone values depend on whether you are a woman or a man.
In the case of women, the FSH hormone may be high due to the presence of a low ovarian reserve and even after menopause. In addition, the administration of contraceptives, Turner's syndrome or pituitary tumors can also cause an increase in the concentration of FSH hormone.
On the other hand, men with elevated FSH hormone levels may have their origin in cancer treatments (chemotherapy or radiotherapy), pituitary tumors and Klinefelter's syndrome. In addition, it is quite common for older men to show high FSH hormone values.
