vitrofertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) for infertile patients. Insulin like growth factor 1 (IGF1), Dehydroepiandrosterone sulfate (DHEAS) and Total Testosterone (TT) may have a role on follicle growth, oocyte quality, embryo quality and subsequent pregnancy in patients undergoing IVF cycles. To explore the possibility of using DHEAS, TT and IGF1 as predictive indicator for successful pregnancy in patients undergoing (IVF/ICSI-ET). A prospective study was performed enrolling (12) non pregnant control group,(7) pregnant control group,(18) non-pregnant PCOS group and (12) pregnant PCOS group. The collection of blood and follicular fluid (FF) samples was done at the day of oocyte aspiration. Electrochemiluminescence immunoassay (ECLIA) method was used to measure DHEAS levels, Chemiluminescence immunoassay (CLIA) method was used to measure TT levels and competitive enzyme-linked immunosorbent assay (ELISA) was used to measure IGF1 levels. Mean of FF DHEAS, serum DHEAS, FF TT and FF IGF1 were higher in pregnant control group than those of non-pregnant control group. The differences were statistically significant (except for serum DHEAS). Additionally, mean of FF DHEAS, serum DHEAS, FF TT, and FF IGF1 were statistically significant lower in pregnant PCOS group than those of non-pregnant PCOS group. Correlation analysis of control group revealed positive association between FF DHEAS and serum DHEAS levels with fertilization rate and cleavage rate. Correlation analysis of PCOS group found.
