Relation between embryo transfer distance from the fundus and the pregnancy rate / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the association of embryo transfer distance from the fundus (TDF) with the clinical pregnancy rate (PR).</p><p><b>METHODS</b>Between January 2005 and September 2006, ultrasound (US)-guided embryo transfer was conducted in 610 women. TDF was measured by transabdominal US according to which the subjects were divided into 4 groups. The association between TDF and PR or between TDF and abnormal pregnancy was analyzed.</p><p><b>RESULTS</b>No significant differences in PR were observed among those 4 groups, but PR was the highest in the group with TDF >or=2 cm, and the lowest in the group 1 cm. The rate of early spontaneous abortion was higher in the group with TDF >or=2 cm.</p><p><b>CONCLUSION</b>TDF variation does not produce significant difference in PR, but the distance of 1.0-2.0 cm is recommended.</p>
