I would like to discuss your article.

In order to avoid pressure changes by activating a syringe by hand I invented

Congrats to this interesting paper.

Please can you describe your OPU technique.

SL or DL Needle, flushing or not flushing etc.

 My aim was to invent a technique to achieve an optimal percentage of eggs/ follicle. www.ivfetflex.com

Thin needle 19gauge for flushing. Option to flush follicles selectively.

There is no place to believe or not believe in flushing follicles, if  you use a properNeedle for flushing.

I would be happy to offer you a clinical trial with my needle or discussion via
