Clomiphene is often used first for inducing ovulation in PCOS; about 60-85% ovulate, with 30% conceiving. Letrozole has shown higher pregnancy rates and may be more effective in PCOS.
Letrozole, often preferred for PCOS, induces ovulation in about 70-85% of cases, compared to clomiphene’s 60-80%. Letrozole also achieves higher live birth rates.
While both stimulate ovulation, letrozole’s rate of success is slightly higher in PCOS patients, often producing fewer side effects than clomiphene.
Clomiphene is often effective for PCOS-related infertility, but studies suggest letrozole has a higher ovulation and pregnancy rate, making it a preferred first-line option.
