METHODS: We investigated if mid-luteal estradiol levels could predict the outcome in intracytoplasmic sperm injection embryo transfer (ICSI-ET) cycles ( n=231). Pregnant and non-pregnant women were compared regarding their peak estradiol levels on human chorionic gonadotropin (hCG) injection day, and mid-luteal estradiol levels on the 7th day following oocyte recovery. Pregnancy rates of the groups that were designed according to the "peak/mid-luteal estradiol level" and the mid-luteal estradiol levels were also compared. RESULTS: Peak and mid-luteal estradiol levels in pregnant women were higher than in non-pregnant women in all patients, although the difference between peak and mid-luteal estradiol levels were similar in pregnant and non-pregnants. Pregnant women had higher mid-luteal estradiol levels in good responders, but the peak estradiol levels of pregnant and non-pregnant women were similar. In poor responders, pregnant and non-pregnant women were similar with respect to peak and mid-luteal estradiol levels. Both in all patients and good responders, women with mid-luteal estradiol levels <200 pg/ml had lower pregnancy rates than those with >2000 pg/ml. Peak/mid-luteal estradiol ratios of pregnant and non-pregnant women were not significantly different in all patients, good responders and poor responders; although a tendency for a lower ratio in pregnants was encountered in good responders. Pregnancy rates of the groups according to the "peak/mid-luteal estradiol ratio" were similar; in all patients, good responders and poor responders. CONCLUSION: A relation between the mid-luteal estradiol level and the outcome is encountered only in good responders.
