A survey of Australian assisted reproduction technique (ART) units revealed many (> 50%) use @entity1671 of the follicle in addition to direct @entity1173 of the fluid during oocyte retrieval. The rationale is that @entity1671 offers an advantage to the @entity1 , with a larger number of oocytes being collected and thus a higher potential for pregnancy Following a complication in a @entity1 , the medical staff determined that @entity1671 might have been implicated. While this was later shown to be unfounded, the unit changed the method of oocyte collection, thus providing an opportunity historically to evaluate the differences between @entity1173 of follicular fluid alone or with additional @entity1671 of each follicle. Thus the aim of this analysis was to test the hypothesis that @entity1173 alone does not effect the outcomes of ART with respect to oocyte numbers collected, their quality and subsequent fertilisation, or ultimate pregnancy rate in a large @entity1 group (n = 2378). During the review period (1991-1993) the manufacturer of the @entity1173 needles; the pump and pressure used for @entity1173 ; the staff involved in all procedures; and the premises, equipment and media used for oocyte collection and culture remained constant. Similarly the two @entity1 groups did not differ in their demographics and physical characteristics. There was no difference (p > 0.5) in the number of oocytes collected, the number of embryos created or the pregnancy rate for that treatment cycle. There was also no significant difference between the two groups in fertilisation rates, irrespective of the type of treatment being used @entity52 ( @entity52 ), gamete intrafallopian transfer (GIFT) or intracytoplasmic sperm injection (ICSI)). The data presented in this paper are not prospective. They use historical comparison and are confounded by minor changes in ovarian stimulation protocols, but the conclusions are still valid. These data suggest there is no difference in the outcome of ART (from oocyte collection through to pregnancy rate) whether or not @entity1173 of follicles is accompanied by @entity1671 . First principles of surgery advocate the shortest possible operating time, the simplest procedure and minimum amount of tissue handling as maxims for reducing complication. Therefore, as a routine, @entity1671 would seem superfluous in ART.
