High fsh levels in men may mean the testicles are not functioning correctly due to:
advancing age (male menopause)
damage to testicles caused by alcohol abuse, chemotherapy, or radiation
problems with genes, such as klinefelter syndrome
treatment with hormones
certain tumors in the pituitary gland.
It is also essential for men to have normal levels of the FSH hormone. An imbalance of this hormone in men can contribute to infertility. For men, FSH controls sperm production which is of course essential to fertility.
Typically, a man’s follicle-stimulating hormone levels should be between 5 and 15 IU/L. High levels of FSH in a male could indicate that the testicles are not functioning properly, or may have been damaged by some condition. They can also indicate the presence of Klinefelter syndrome, a genetic disorder that causes the presence of too many X chromosomes in the male.
So get semen analysis done, and consult with some good infertility specialist.
