IVF/ET has during the last 5 years gone through a dramatic development and expansions. Since approx. 10% of the population in fertile ages has infertility problems in the Western world the demand for IVF units outside larger University hospitals with considerable resources has become urgent. To reduce costs a trend towards simplification without loss in quality has been an ambition for everyone involved. The exchange of laparoscopic techniques to simpler and cheaper sonographic methods is one step in that direction. The present review is a comparison between the various techniques for oocyte retrieval taking into consideration the principle qualitative aspects to avoid introducing a new technique which is inferior to the originally applied technique. In summary sonographic techniques seem to fullfill these quality requirements and will for such reasons in many IVF groups gradually replace laparoscopy.
