Letrozole is an orally active, nonsteroidal, selective aromatase inhibitor and hence an antiestrogen. It prevents aromatase from producing estrogens by competitive, reversible binding to the heme of its cytochrome P450 unit. The action is specific, and letrozole does not reduce production of corticosteroids. [citation needed
Aromatase inhibitors affect the ability of estrogens production from androgens by inhibiting the aromatase enzyme activity which is a part of the estrogen pathway. [13] The two categories of AIs are based on their mechanism of action and structure.

Ovarian stimulation with the aromatase inhibitor letrozole has been proposed for ovulation induction in order to treat unexplained female infertility. In a multi-center study funded by the National Institute of Child Health and Development, ovarian stimulation with letrozole resulted in a significantly lower frequency of multiple gestation (i.e., twins or triplets) but also a lower frequency ...
α-Naphthoflavone is a potent inhibitor of the enzyme aromatase, the enzyme that converts testosterone to estrogen. [ 1 ] [ 2 ] α-Naphthoflavone has been shown to cause abnormal testicular development in young chickens.
Aromatase (EC 1.14.14.14), also called estrogen synthetase or estrogen synthase, is an enzyme responsible for a key step in the biosynthesis of estrogens.It is CYP19A1, a member of the cytochrome P450 superfamily, which are monooxygenases that catalyze many reactions involved in steroidogenesis.
1,4,6-Androstatriene-3,17-dione (ATD) is a potent irreversible aromatase inhibitor that inhibits estrogen biosynthesis by permanently binding and inactivating aromatase in adipose and peripheral tissue. [1] It is used to control estrogen synthesis. [2]
