Common reasons for high FSH:

  • High FSH usually reflects reduced gonadal feedback.

    In men, it is seen with primary testicular dysfunction or impaired spermatogenesis.

    In women, it rises physiologically with perimenopause and menopause, and outside that setting may suggest primary ovarian insufficiency, ovarian failure, or Turner syndrome.
