Ultrasonically guided transfer of embryos was performed transabdominally in 10 patients. The uterus was punctured by a 16-gauge needle with a stylet through a full urinary bladder. When the needle tip was in the uterine cavity the stylette was removed and a transfer catheter loaded with the embryos was inserted. No complications or technical difficulties were experienced. None of the patients became pregnant.
