- OBJECTIVE
To investigate the clinical significance of endometrial thickness and pattan as a predictor of successful implantation of embryos in ovum donation and cryopreserved-thawed embryo transfer program. METHODS: From January, 1996 to March, 1998, 31 cycles of ovum donation and 31 cycles of cryopreserved-thawed embryo transfer were enrolled in this prospective study. Endometrial thickness was measured three times: prior to progesterone administration (P), 1 day and 3 days after P. In cryopreserved-thawed embryo transfer cycles, the measurement at 1 day after P was omitted. Endometrial pattern was observed prior to progesterone, and was considered meaningful when a multi-layered triple-line was seen with prominent outer and central hyperchogenic lines and inner hypoechogenic regions. RESULTS: There were no differences in embryo quality, dose or duration of estrogen, and endometrial thickness or pattern between conception and non-conception cycles in both ovum donation and cryapreserved-thawed embryo transfer pmgram. In ovum donation cycles, no cortelation was observed between estrogen dose and endometrial thickness or pattern. In cryopreserved-thawed embryo transfer cycles, total estrogen dose and endometral thickness at 3 days after P has a inverse correlation, and estrogen dose over 4.3 mg per day can predict expression of a multi-layered triple-line pattern, CONCLUSION: Endometrial thickness or pattern. cannot predict a successful implantaion of embryos in both ovum donation and cryopreserved-thawed embryo transfer cycles.
