Conclusions
ovulatory dysfunction
Our study found no significant difference in the ovulation rates of infertile women with ovulatory dysfunction. Specifically, the rates achieved with a combination of CC and letrozole were not significantly different from those achieved with CC 50 mg alone in one cycle. However, the low number of live births precluded statistical analysis. According to the limitations mentioned above, future studies with larger sample sizes and extended follow-up periods or equivalence trials are needed to evaluate the cumulative ovulatory rates and dose-defining efficacy of these ovulation-induction regimens.
