Abstract：Objective To evaluate the value of serum E2 levels during COH in predicting IVF-ET outcome. Method Data from 311 IVF-ET cycles received long protocol were collected and analyzed according to E 2 levels 5 days after stimulation:Group A (E2≤500 pmol/L), Group B (500<E2≤1 000 pmol/L), Group C (1 000<E2≤1 500 pmol/L), Group D (1500 < E2≤2 000 pmol/L) and Group E (E2> 2 000 pmol/L). Results In groups with E2>1 000 pmol/L, the conditions of oocyte and embryo are higher than E2<1 000 pmol/L. With the increase of E2 levels, period cancellation rate increases. When E2> 2 000 pmol/L, the pregnancy rate become lowest. Conclusion E2 levels among 1 000~1 500 pmol/L during early COH predicts a better pregnancy outcome.
