We investigated a reliable FSH range to retrieve more oocytes and embryos. Materials and Methods: Two hundred patients in ART cycles underwent this study from Apr 2007 to Sep 2008. Patients were divided in three groups based on value of FSH: group A≤8 IU/ml, 8 IU/ml < group B≤10 IU/ml, group C>10 IU/ml and results of ART cycles were compared with each other. Results: Retrieved and fertilized oocytes and transferred embryos in group A differed significantly in comparison with group B and C (p<0.05), but pregnancy rates in three groups were comparable. Conclusion: In our study the reliable range of FSH level to predict more retrieved oocytes and embryos was ≤8 IU/ml. https://jfrh.tums.ac.ir/index.php/jfrh/article/view/81 https://jfrh.tums.ac.ir/index.php/jfrh/article/download/81/81
