Correlation between estradiol levels on day of HCG trigger and the number of mature follicles, number of oocytes retrieved, and the number of mature oocytes (M2) after oocyte aspiration in ICSI cycles

Abstract Background Estradiol is an important marker of ovarian response to stimulation in ART cycles. The study tries find the correlation serum estradiol on day HCG trigger number follicles, oocytes retrieved, and mature oocytes, also, correlate per follicle oocyte HCG, oocytes. It a cross sectional using retrospective data. Results data 232 patients were analyzed. Our showed positive between levels follicles (NF) ( r = 0.592, p < 0.001), retrieved (NRO) 0.576, (NMO) 0.554, 0.001). E/follicle ratio did not have significant with NRO NMO. E/Oocyte had strong negative NMO −0.280, 0.001) Conclusions Serum NF, NRO, But E/O These results indicate that can be used as clinical tool prediction yield Reproductive outcome cycles largely dependent yield. appear strongly
