The technique for human embryo transfer at Tygerberg Hospital

Kruger T.F. ; Stander F.S.H. ; Van Der Merwe J.P. (1986)


From 1 May 1984 to 30 April 1985, 177 laparoscopies were performed; 684 oocytes were obtained and a fertilization rate of 85% per oocyte achieved. There was a pregnancy rate of 24,3% per embryo transfer (ET) and 20,9% per laparoscopy after 152 patients were subjected to ET. Th ET technique at Tygerberg Hospital, using the Tomcat catheter, is described. An introducer - the FT introducer - designed to overcome technical difficulties in selected patients in passing the Tomcat catheter is described. Technical problems are easily overcome with this introducer. In 26 patients (17,1%) ET was performed using this instrument and 8 pregnancies resulted (a pregnancy rate of 30,7% per ET). This pregnancy rate indicates the value of the instrument.
