Effect of Degranulation Needle With Different Diameters on the Rate Good Embryo in IVF

Good-quality embryos are critical for the success of in vitro fertilization (IVF). But, to date, there is no report of the effect of different diameters denuding pipette on the embryos quality. To investigate the effect of denuding pipette in IVF outcomes, we plan to recruit women undergoing IVF treatment cycles and classified them into two groups according to the different diameters. Consequently, the rate of fertilization, zygotes cleaved, top quality embryos on D3, and blastocysts obtained were recorded.
