XYClone for Laser-assisted IVF

"A main criteria for successful IVF is the use of sperm with acceptable motility, concentration, and forward movement. If one or more of these parameters is suboptimal, the ability to fertilize oocytes can be severely limited. In these cases, an XYClone™ laser is used to create 2-3 holes in the zona pellucida of each oocyte providing a means for less motile or less progressive sperm to penetrate the oocyte and induce fertilization. This procedure has greatly enhanced the fertilization efficiency of various genetically-modified lines and is a vital tool in the rescue of valuable rodent strains." Charles River Laboratories

Benefits of Laser-assisted IVF

  • Increase fertilization rates with mutant and low motility sperm
  • Increase overall throughput and production
  • Significantly reduces the need for ICSI

Laser Assisted IVF: A Simple Technique to Improve IVF in Mice without Micromanipulation (Download full poster)

CONCLUSIONS

  • Zona laser dissection of mouse oocytes significantly improved the fertilization rate following IVF.
  • This simple swift technique avoided micromanipulation and problems associated with ICSI. Furthermore, the reduced operator time allowed numerous oocytes to be treated in a short period.

There was normal development to blast and onward to hatching using XYClone laser for assisted IVF. Oocytes undergoing laser assisted IVF hatched 8-12 hours sooner than conventional IVF.
