Abstract
ObjectiveTo determine the effect of luteinized unruptured follicle (LUF) cycles on frozen thawed embryo transfer (FET).DesignA retrospective analysis comparing the clinical outcomes after FET among 144 cases of luteinized unruptured follicle (LUF) cycles and 866 cases of ovulation cycles.SettingReproductive medical center, Beijing China.PatientsChinese infertile women who underwent FET.InterventionsNone.Main outcome measuresClinical pregnancy rate (PR), implantation rate.ResultsThe implantation rate, clinical pregnancy rate, on-going pregnancy rate and live birth rate in LUF group were 12.76% (49/384), 27.78% (40/144), 24.31% (35/144) and 19.44% (28/144), respectively, and in ovulation group, 14.74% (332/2251), 31.29% (271/866), 28.29% (245/866) and 22.23% (193/866), respectively (p > 0.05).ConclusionsLUF does not affect the clinical outcomes of FET. Patients of LUF should be included in FET treatment.
