Ovulation induction is a key fertility treatment that helps women who experience irregular ovulation or anovulation conceive successfully. Among the most commonly prescribed medications are Letrozole and Clomiphene Citrate, both proven to stimulate ovulation—but in different ways.
Understanding how these treatments work can help you make informed decisions on your fertility journey.
What is Ovulation Induction?
Ovulation induction is a medical process that stimulates the ovaries to release eggs. It is commonly recommended for women with:
- Irregular menstrual cycles
- Polycystic Ovary Syndrome (PCOS)
- Hormonal imbalances
- Unexplained infertility
How Clomiphene Citrate Works
Clomiphene Citrate (CC) is a Selective Estrogen Receptor Modulator (SERM) that works by:
- Blocking estrogen receptors in the brain
- Increasing GnRH hormone release
- Stimulating FSH and LH production
- Promoting follicle growth and ovulation
Benefits:
- Widely available
- Effective for many ovulatory disorders
Limitations:
- May thin the endometrial lining
- Can affect cervical mucus quality
How Letrozole Works
Letrozole is an aromatase inhibitor that reduces estrogen production temporarily. This leads to:
- Increased FSH secretion
- Better follicular development
- Improved ovulation rates
Benefits:
- Better endometrial thickness
- Fewer anti-estrogen effects
- Shorter half-life (less side effects)
Letrozole vs Clomiphene: Which is Better?
- Letrozole is now considered the first-line treatment for PCOS patients
- It shows higher ovulation and live birth rates
- Clomiphene is still useful in:
- Unexplained infertility
- Mild ovulatory issues
- When Letrozole is not suitable
The best choice depends on your individual fertility condition.
How Treatment is Monitored
Both medications are usually taken early in the menstrual cycle. Doctors may recommend:
- Ultrasound scans to track follicle growth
- Hormone monitoring
- Timed intercourse or IUI
