Description
💊 Letrozole for Fertility – LETROMED Human Labs
Letrozole is a non-steroidal aromatase inhibitor that lowers estrogen levels by blocking the enzyme aromatase.
While approved as a breast cancer treatment in postmenopausal women (PharmaWiki), it is also widely prescribed off-label for fertility treatment – especially in women with ovulation disorders such as PCOS.
⚕️ How Letrozole Helps Fertility
By reducing estrogen levels, letrozole increases the release of FSH (follicle-stimulating hormone), which stimulates ovulation.
This mechanism makes it an alternative to clomiphene for women who do not respond to standard fertility treatments.
