title: [The importance of the sonographic control for a successful embryotransfer after in vitro fertilization].
abstract: Two groups of patients have been assessed for a period from January 2000 till Mai 2004. In the first group of 222 patients the Embryotransfer was performed without sonographic control. In the second group of 253 patients the transfer was sonographically controlled. The results of the second group - 54,1% pregnancy rate per transfer are statistically better than of the first group - 29,3% pregnancy rate. ET performed under sonographic control improves significantly the results.
