Background & Aims : To evaluate the effects of cryopreservation and setting an eye on changes in the blood Estradiol (E<SUB>2</SUB>), Progesterone (P<SUB>4</SUB>) levels and thickness of the endometrium before and after the transfer.<BR>Methods : We studies whether these parameters can give us a clue to the mechanism leading to implantation and pregnancy from January 1999 to December 2000, 269 patients underwent 860 thawed embryo transfers.<BR>Results and conclusions : 57 out of 269 cases achieved pregnancy, the pregnant rate being 21.2%. Abortion occurred in 23 cases, the abortion rate being 40.3%. No significant difference was found in mean age, mean number of embryo transfer, total score of embryo transfer in the Veeck's classification and mean score of embryo transfer between the pregnant and non pregnant cases. Pregnant cases tended to have many embryos of high grade transferred. No significant difference was found in blood E<SUB>2</SUB>, P<SUB>4</SUB> levels and thickness of the endometrium in the pregnant and non pregnant cases.<BR>There was no difference in mean age, mean number of embryo transfer, total score of embryo transfer in the Veeck's classification, mean score of embryo transfer and number of grades between the pregnant continuation cases and abortion cases. The cases of abortion showed a relatively high blood E<SUB>2</SUB>, level compared with the cases of clinically continued pregnancy. No difference in the blood P<SUB>4</SUB> level and thickness of the endometrium was found between the two. The changes in these parameters can be used a guide in predicting prognosis of the pregnancy.
