Q.
I didn’t have any success with Clomid, and my doctor has suggested I try letrozole or go straight to injectables. What are your thoughts?
A.
Clomid (clomiphene citrate) and letrozole (Femara) are both oral medications aimed at stimulating ovulation. Letrozole is gaining traction as a solid alternative to Clomid for women seeking ovulation induction, although we still don’t have large-scale scientific studies to declare it as the standard first-line treatment. Early research indicates that letrozole can be beneficial for women who have trouble ovulating, and it tends to have fewer side effects, especially for those whose uterine lining might be adversely affected by Clomid.
Letrozole works as a nonsteroidal aromatase inhibitor, which specifically reduces estrogen production. When estrogen levels decrease, FSH (follicle-stimulating hormone) levels rise, encouraging ovulation. Initially developed for breast cancer treatment, letrozole has shown promise for a specific group of anovulatory women, particularly those who might experience a thinning of the endometrial lining with Clomid. Clomid can inhibit the growth of the uterine lining, making it harder for an embryo to implant. Interestingly, letrozole seems to have a lesser impact on the uterine lining. Plus, letrozole has a shorter duration of action compared to Clomid, which can linger in the body for 4-6 weeks after taking it. Overall, we’re optimistic about the results we’ve seen with letrozole so far, and we’re looking forward to more studies to confirm its effectiveness as a standard treatment option.

In summary, both Clomid and letrozole have their uses in ovulation induction, with letrozole becoming a popular choice due to its effectiveness and fewer side effects on the uterine lining. As always, it’s best to consult your healthcare provider to determine the best plan for your situation.
