Femara, or letrozole, works by blocking the enzyme aromatase. This enzyme converts androgens (male hormones) into estrogens (female hormones). By inhibiting aromatase, Femara increases the levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
Higher FSH levels stimulate the ovaries to produce more follicles, each containing an egg. Increased LH triggers ovulation, the release of a mature egg from the follicle. This enhanced hormonal environment improves the chances of egg maturation and successful fertilization.
Doctors typically prescribe Femara for 5 days, beginning on cycle day 3-5. Blood tests and ultrasounds monitor follicle development and guide treatment adjustments. Successful ovulation is confirmed through further testing.
Remember, individual responses to Femara vary. A fertility specialist will tailor the dosage and treatment plan according to your specific needs and medical history. They’ll also discuss potential side effects, such as hot flashes or headaches, and alternative options if necessary.
Success rates with Femara vary depending on factors like age, overall health, and underlying causes of infertility. Consult with your doctor for personalized advice and to determine if Femara is the right treatment for you.
