Summary
Initially, oocyte retrieval was considered a significant challenge and originally performed by laparotomy and/or by other laparoscopic techniques. However, apart from the complexity of such techniques, the overall success rate was less than 50% due to severe tubal disease, multiple adhesions, or hidden ovaries. Improvement in the success rate of ovum pickup (OPU) to 60–80% per follicle occurred between 1979 and 1980, upon the introduction of a foot-controlled fixed aspiration pressure control and upon an integration of specially designed teflon-lined aspiration needles with beveled points.
