Dear colleagues! Graz, August 2019
Book „Controversies in Assisted Reproduction“ Edited by Botros Risk und Yakoub Khalaf, Cambridge Univ. Press will be published very soon.
My chapter 10 : Flushing follicles.
My main message in this chapter: New paradigm for success in ART is Cumulative PR Every follicle has to be flushed indepently of number of follicles.
80 % colleagues worldwide are not flushing follicles. They are right: because with current DL Needles on the market they would retreeve the same number of oocytes in comparison with SL needles without flushing. Also they avoid disadvantages of DL needles: 3x longer duration of the procedure, painful thick needle, at least 1/3 more expensive.
20% of centers are flushing. Disadvantage see above.
I was successful to create a new needle and flushing technology with a SL Needle. The SL Needle can be produced in 17, 19 and even 21 gauge for flushing follicles, leading to remarkable reduced pain release and 3-4 fold shorter OPU procedure in comparison with DL needles.
A mechanical or electronical flushing pump enables physitian to choose amount and pressure of injected flushing fluid by activating a pedal or button.
The mechanical pump can be used in combination with any Aspiration Pump. STEINER COMBI PUMP is a combination of aspiration and flushing in 1 device. A warming element for 50cc syringe guarantees constant temperature at 37°

The trigger for this paper is a publication, published in Fert. Ster. Febr. 2017 (1) with main message, that we can increase our Cumulative Pregnancy Rate (Fresh plus Kryo Cycle) in IVF by 8% with every additional egg, which we harvest.
There is no doubt, that Egg Collection is a crucial step in IVF. Unfortunately we have no Guide Lines for this important procedure. Approx. 20% of IVF Centers worldwide are using Double Lumen Needles for OPU. 80 % Single Lumen Needles. The argument, not to flush follicles is frequently: “I do not believe in flushing, because the number of eggs are the same as with flushing, therefore flushing would be waste of time”. The reason for this phenomenon is not flushing per, but insufficient physical properties of a DL Needles on the market. The answer for this question has Poiseuille`s law. As soon as we increase the inner diameter of a needle out of 19%, the aspirated volume is doubled. In a DL Needle, the flow volume would decrease more than 50% together with remarkably reduced turbulences during both, aspiration and flushing as well due to narrowed inner lumen.
The physical properties of STEINER-TAN Needle in 17, 19, 21gauge for flushing is the solution how to prevent disadvantages of a DL Needle. (2). It is a SL Needle flushed from outside needle, flushing starting 7cm proximal of needle tip. For the first time it is possible to study in Egg Collection each follicle separately. Schenk et al.(3) All studies in the past, comparing flushing vs. non flushing, had ignored the dead space of at least 1300mm (Needle plus tubing).
Conclusion: The new Paradigm with definition of success rate in IVF as Cumulative Pregnancy Rate together with an appropriate Egg Collection Technique, that means flushing follicles with the right needle, based on Law of Physics will be the future in ART. Our patients have the right, that we retrieve as much eggs/ follicle as possible and we physicians have to accept the compromise, that duration of OPU procedure will take us a few minutes longer.
