Hi, Dr. Lisa Vigue here today! I just wanted to talk a little bit about fertility treatments that are available to women who are having difficulty with becoming pregnant or with irregular menstrual cycles. There are many different options to help couples start a family. Today we’re going to talk about oral medications you can take to help you ovulate.
Ovulation induction is a common treatment for women who have irregular ovulation or do not ovulate at all. Two of the most frequently used medications for this purpose are Clomid (clomiphene citrate) and Femara (letrozole). Here’s an overview of each:
Clomid (Clomiphene Citrate)
- Mechanism of Action**: Clomid works by blocking estrogen receptors in the brain, specifically in the hypothalamus. This blockage tricks the brain into thinking estrogen levels are low, which stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones encourage the ovaries to develop and release a mature egg, inducing ovulation.
- Administration: Clomid is typically taken orally for five days early in the menstrual cycle, usually starting on day 3, 4, or 5 of the cycle.
- Success Rates: Clomid successfully induces ovulation in about 80% of women who take it, and approximately 40-50% of those women will conceive within six cycles.
- Side Effects**: Common side effects include hot flashes, mood swings, bloating, and headaches. Clomid can also thin the uterine lining, which may reduce the chances of implantation.
Femara (Letrozole)
- Mechanism of Action: Femara is an aromatase inhibitor, meaning it reduces the amount of estrogen produced by the body. Lower estrogen levels lead to a release of FSH and LH, similar to Clomid, which stimulates the ovaries to produce and release an egg.
- Administration: Like Clomid, Femara is taken orally for five days, typically starting on day 3, 4, or 5 of the menstrual cycle.Success Rates: Femara is often used as an alternative to Clomid, especially for women who do not respond to Clomid or have certain conditions like polycystic ovary syndrome (PCOS). Studies suggest that Femara might be slightly more effective than Clomid, with higher ovulation and pregnancy rates in some cases.
- Side Effects: Femara generally has fewer side effects than Clomid. However, some women may experience fatigue, dizziness, or headaches. Unlike Clomid, Femara does not typically affect the uterine lining, making it a preferred option for some women.
Comparison
- Effectiveness: Both medications are effective in inducing ovulation, but Femara may have a slight edge in certain populations, particularly in women with PCOS.
- Side Effects: Femara tends to have fewer side effects and is less likely to cause thinning of the uterine lining.
- Cost and Availability: Both medications are widely available, though the choice between them may depend on individual health factors and how a woman responds to treatment.
- Considerations: When choosing between Clomid and Femara, doctors will consider factors like the woman’s age, ovarian reserve, underlying causes of infertility, and previous responses to fertility treatments. Both medications can be effective, but close monitoring by a healthcare provider is essential to adjust dosages and ensure the best possible outcome.
