The addition of letrozole to COS did not have any negative effect on the number of mature oocytes collected (MR = 1.00, 95% CI = 0.87-1.16; P = 0.967) and the other efficacy endpoints. COS with letrozole was associated with significantly decreased peak estradiol levels (MR = 0.28, 95% CI = 0.24-0.32; P less then 0.001). Similar results were observed in the secondary analysis including only breast cancer patients. Conclusions These findings are reassuring on the efficacy and safety of COS with gonadotropins and letro
