Evaluation and Management of Elevated FSH Levels in Males

Initial Assessment and Testing

A complete semen analysis (at least two samples, one month apart) to evaluate sperm concentration, motility, and morphology is recommended for men with elevated FSH levels, as per the American Academy of Family Physicians 1
Physical examination focusing on testicular size and consistency, presence of varicocele, and secondary sex characteristics is also recommended for men with elevated FSH levels, as per the American Academy of Family Physicians 1

If semen analysis shows abnormalities and FSH is elevated, genetic testing may be warranted, according to the American Urological Association 2
Karyotype testing should be considered if sperm concentration is <5 million/mL with elevated FSH, as recommended by the American Urological Association 2
Y-chromosome microdeletion testing for men with severe oligospermia or azoospermia is also recommended by the American Urological Association 2
For men with idiopathic infertility and elevated FSH, FSH analogue treatment may be considered to improve sperm concentration and pregnancy rates, though benefits are limited, as noted by the American Urological Association 3, 5
Exogenous testosterone administration should be avoided in men concerned about fertility, as it can suppress spermatogenesis, according to the American Urological Association 4

FSH level alone should not be the only parameter used to assess fertility potential, as recommended by the American Academy of Family Physicians 1
