Clomid Success Rates

Clomid, an oral fertility drug, is typically started at a 50 milligram (mg) dosage, and your fertility doctor will determine whether this dosage is helping you to ovulate. If you are not ovulating, your fertility doctor will increase the dosage incrementally.

Your fertility doctor will use the lowest dose of Clomid that is sufficient to induce ovulation for at least four to six cycles. Clomid will induce ovulation in about 80 percent of properly selected patients, according to the American Society for Reproductive Medicine’s Medications for Inducing Ovulation. Approximately 40 to 45 percent of women will become pregnant within six cycles after receiving Clomid. If a couple has no other fertility issues, their odds of getting pregnant when using Clomid can range from 10 percent to 20 percent, similar to a fertile couple trying on their own.

Women who have very low estrogen levels, irregular or absent ovulation due to a hypothalmic disorder, or who are obese have less chance of success on Clomid. (For obese women, losing weight may increase the chances of success.) After six cycles of Clomid, the chances for success decrease significantly, and experts recommend moving to an alternative, such as in vitro fertilization (IVF).
