Introduction to Letrozole and Its Effects

Letrozole is a medication primarily used in the treatment of hormone-sensitive breast cancer and, increasingly, for other off-label uses such as fertility enhancement. The Letrozole effect refers to the various physiological and hormonal changes induced by this drug, which can impact patients differently based on their health status and treatment goals.

How Does Letrozole Work?

Mechanism of Action

The primary action of Letrozole involves inhibiting the enzyme aromatase, which converts androgens into estrogens. This reduction in estrogen levels leads to:

• Decreased estrogen production in postmenopausal women
• Suppression of estrogen-driven tumor growth
• Alteration of hormonal balance that can influence ovulation and fertility
