What is Letrozole?
Letrozole is an aromatase inhibitor that was initially developed to treat hormone receptor-positive breast cancer. However, its ability to suppress estrogen production has made it an effective tool for inducing ovulation in women with fertility issues. By inhibiting the enzyme aromatase, which converts androgens into estrogen, letrozole creates a temporary state of reduced estrogen levels, prompting the body to increase follicle-stimulating hormone (FSH) production.
This mechanism is particularly beneficial for women with polycystic ovary syndrome (PCOS) or other conditions that disrupt normal ovulation. Unlike clomiphene, another commonly prescribed fertility medication, letrozole does not affect the uterine lining, making it a preferred choice for many fertility specialists.
Key Characteristics of Letrozole
- It is taken orally, making it convenient for patients.
- Its effects are reversible, reducing long-term risks.
- It has a lower incidence of multiple pregnancies compared to clomiphene.
How Does Letrozole Work for Fertility?
Letrozole works by inhibiting the enzyme aromatase, which is responsible for converting androgens into estrogen. This reduction in estrogen levels signals the hypothalamus and pituitary gland to produce more FSH, which stimulates the growth and maturation of ovarian follicles. The result is an increased likelihood of ovulation, which is essential for conception.
Research published in the New England Journal of Medicine highlights the efficacy of letrozole in treating anovulatory infertility, particularly in women with PCOS. The study found that letrozole was more effective than clomiphene in achieving live births, making it a valuable option for fertility treatment.
Letrozole vs. Clomiphene: Which is Better?
Both letrozole and clomiphene are widely used to induce ovulation, but they differ in their mechanisms of action and side effect profiles. Clomiphene works as a selective estrogen receptor modulator (SERM), blocking estrogen receptors in the brain to increase FSH production. However, it can negatively affect the uterine lining, reducing the chances of implantation.
In contrast, letrozole does not interfere with the uterine lining, making it a better option for improving implantation rates. Additionally, letrozole has a lower risk of multiple pregnancies, which is a significant concern for many patients undergoing fertility treatment.

Common Side Effects of Letrozole
While letrozole is generally well-tolerated, some women may experience mild side effects. These include:
- Hot flashes
- Headaches
- Nausea
- Mood changes
- Joint pain
It's important to discuss any side effects with your healthcare provider to ensure the medication is appropriate for your specific needs.
Dosage Guidelines for Fertility Treatment
The standard dosage for letrozole in fertility treatment is 2.5 mg per day, taken for five days starting on the third day of the menstrual cycle. However, your doctor may adjust the dosage based on your individual response and medical history.
It's crucial to follow your healthcare provider's instructions carefully and attend regular monitoring appointments to ensure the treatment is proceeding as expected. Ultrasound scans and blood tests may be used to track follicular development and hormone levels.
Risks and Precautions
While letrozole is generally safe, there are certain risks and precautions to consider:
- Pregnancy Monitoring: Women taking letrozole should undergo regular monitoring to ensure the treatment is effective and safe.
- Pre-existing Conditions: Inform your doctor if you have any pre-existing medical conditions, as they may affect your suitability for letrozole.
- Potential Risks: Although rare, letrozole may increase the risk of ovarian hyperstimulation syndrome (OHSS) in some cases.
Clinical Studies Supporting Letrozole for Fertility
Several clinical studies have demonstrated the efficacy of letrozole in treating infertility. A landmark study published in the New England Journal of Medicine found that letrozole resulted in higher live birth rates compared to clomiphene in women with PCOS. Another study published in Fertility and Sterility highlighted letrozole's effectiveness in improving ovulation rates and pregnancy outcomes.
These studies, along with numerous others, provide strong evidence supporting the use of letrozole in fertility treatment. However, it's essential to consult with a qualified healthcare provider to determine if letrozole is the right choice for your specific situation.
