Reliable Range of Basal FSH for prediction of ovarian reserve

Objective: basal fsh levels reflect ovarian response and more formed embryos. 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.
