Subendometrial blood flow was evaluated. The resistance index (RI), systolic/diastolic ratio (S/D) and pulsatility index (PI) were significantly lower in those who achieved pregnancy as compared with those who did not: 0.62±0.04 vs 0.68±0.04 (P<0.001), 2.66±0.33 vs 3.19±0.39 (P<0.01) and 1.15±0.17 vs 1.34±0.22 (P<0.05), respectively. Furthermore, when RI>0.72, PI>1.6, and S/D>3.6, no pregnancy occurred. These data suggest that the parameters of spiral artery blood flow could be used as a new assay in predicting endometrial receptivity before ET.展开更多

Embryos transfers were performed in recipients from 15th to 20th day of hormone replacement therapy cycle. Preclinical preg-nancies were defined when serum β-hCG performed on day 14 post embryo transfer >3. 1ng/ml. Clini-cal pregnancies was diagnosed by the presence of a gestation sac with transvaginal ultrasound at six weeks of gestation.Results:Clinical pregnancy rate per embryo transfer cycle was 35- 2% (19/54). The first baby was deliveried on Jan 14, 1994 in premature ovarian failure patient with hormone replacement therapy and oocyte donation in China. Comharison of the results showed a singnificant increase in number of em-bryos transfer, embryo scoring and clinical pregnancy rate (54. 2 % ) in the whole cohort where oocytes were used. The P value was <0.05, <0. 001, <0.05 respectively. However the spontaneous abortion rate(15. 4% ) significantly decreased (P<0.001 ). No difference was found in the embryos scoring and the number of embryos transfer between groups with age less than 3O years or more than 30 years. But clinical pregnancy rate in the younger group (42. 9% ) was significantly higher than in the older group (30. 3%). The endometrium receptivity window of a 2-days embryo was from 15th to 19th day of a 28 days cycle. The highest pregnancy rate was in day 16 to 18 in the 28 days cycle.Conclusion: Hormone replacement therapy and oocyte donation is a effective method of obtaining successful pregnancy for those with premature ovarian failure. The quality of oocyte is an important factor that affects the pregnancy rate and spontaneous abortion rate. The endometrium receptivity ia al-so a major factor affecting the pregnancy rate, which declined with increasi展开更多
