Common reasons for high Estradiol:

  • In men: High estradiol is seen with obesity / increased aromatization, liver cirrhosis, hyperthyroidism, and estrogen-producing testicular or adrenal tumors. It may be associated with gynecomastia and sexual dysfunction.

    In women: High estradiol is seen physiologically in pregnancy and around ovulation, and can also occur with ovulation induction or estrogen therapy, estrogen-secreting ovarian or adrenal tumors, liver disease, and hyperthyroidism.
