A postal survey of embryo transfer practice in the UK
Department of Reproductive Medicine, Clarendon Wing, Leeds General Infirmary, Leeds, UK
In this postal survey a questionnaire was sent to all unit directors in the UK to determine their attitudes to the factors influencing embryo transfer practice. They were requested to rate each step on a scale of 1-10, where 1 was irrelevant and 10 very important. A total of 80 practitioners from 40 units replied. Over 50% of the corresponding practitioners were consultants, 33% were middle-grade clinicians, and 12% were infertility nurse specialists. The factor that got the highest rating was the need for a standardized protocol for all unit staff regarding embryo transfer technique. The second critical factor voted by the respondents was the presence of blood on the embryo transfer catheter. Not touching the uterine fundus was deemed to be the third most important factor while the type of embryo transfer catheter used was a very close fourth. Prolonged bed rest following embryo transfer was voted the least important factor to influence the outcome. The wide variations in practice and choice of catheters encountered in this survey are indications of the divided opinion and lack of concrete evidence on which to base any firm decisions. The need for large clinical studies to assess clearly whether higher pregnancy rates will result from modifications in embryo transfer practice is highlighted.
Key words: catheter/embryo transfer technique/implantation rates
