Letrozole 2.5mg for fertility: Dosage, Benefits, and More

Research-backed

Letrozole is one of the most commonly used drugs to treat certain types of breast cancer in women post-menopause. They are classic estrogen inhibitors that slow down or prevent the growth and recurrence of cancers. A decade-long discovery of Letrozole is its ovulation-inducing and controlled hyperstimulation agent, as its estrogen inhibiting activity has been quite effective. 

Letrozole 2.5mg is an addition to the armamentarium of infertility treatments. Unlike the most preferred Ovulation Induction Medication, Clomiphene citrate, Letrozole is a class of aromatase inhibitors, suppresses estrogen production, and enhances the release of Follicle Stimulating Hormone (FSH). The side effects compared to other ovulation-inducing drugs are milder. This has helped Letrozole create its own set of fertility enhancement benefits. 

This article talks more about the working and effectiveness of Letrozole 2.5 mg and the milder side effects it carries.

How does Letrozole 2.5mg for fertility work?

During infertility treatment, the ovaries need to produce more follicles and mature eggs. For this, the pituitary glands will need to make more hormones to stimulate the ovaries for follicular growth and production. Women with ovulatory problems have ovaries that do not ovulate or ovulate irregularly. In such cases, the doctors prescribe medications to induce ovulation. 

Letrozole is a class of aromatase inhibitors, works fundamentally by inhibiting/suppressing the enzyme aromatase responsible for estrogen production. It indirectly suppresses the production of estrogens and promotes the release of follicle-stimulating hormone (FSH). FSH is essential for follicle development and growth. 

The sequential action of Letrozole is represented below.
