This technology is an Assisted Reproduction Technology designed as a specific gravity system that estimates the weight of the embryos for determining the viability of embryos.  It is a non-invasive technique that uses specific gravity as an indicator of weight and allows for the heaviest embryos to be selected for implantation.  This safe and simple approach is safe and reliable. 


Market Applications:

This technology is very simple to use and can be used to test human and animal embryos for viability in the clinical and research settings.  This would include hospitals, fertility clinics, veterinary hospitals, and research laboratories. 


Features, Benefits and Advantages:

• Non-invasive, does not harm embryos

• Allows for 100% recovery of embryos

• Detects differences in viability at the earliest stages of development

• Selects most viable embryos


Development Stage:

The Specific gravity system has been tested and has been shown to have 100% recovery of the embryos without causing damage to the embryos.  It has also been shown to be accurate in determining the weight of the embryo.  Further testing with larger embryo cohorts is ongoing.
