Antiestrogens, also known as estrogen antagonists or estrogen blockers, are a class of drugs which prevent estrogens like estradiol from mediating their biological effects in the body. They act by blocking the estrogen receptor (ER) and/or inhibiting or suppressing estrogen production .
Aromatase inhibitors (AIs) are a class of drugs used in the treatment of breast cancer in postmenopausal women and in men, [1] [2] and gynecomastia in men. They may also be used off-label to reduce estrogen conversion when supplementing testosterone exogenously. They may also be used for chemoprevention in women at high risk for breast cancer.

[ 12 ] Exemestane is an irreversible, steroidal aromatase inactivator of type I, structurally related to the natural substrate 4-androstenedione .
It is a mixed agonist and antagonist of the estrogen receptor (ER). Clomifene activates the ERα in the setting of low baseline estrogen levels and partially blocks the receptor in the context of high baseline estrogen levels. [18] Conversely, it is an antagonist of the ERβ. [18] Clomifene has antiestrogenic effects in the uterus. [32]

LHRH (luteinising hormone-releasing hormone) agonists block the production of sex hormones in both men and women. [16] In men, LHRH agonists seize testosterone production in the testicles, and in women it blocks the ovaries from producing estrogen and progesterone. [16] These drugs are most commonly used in treatments for prostate cancer. [16]
