Objective and based on data
Ranks embryos according to their likelihood of:
Basically asks: Which embryo should I transfer?
We have a choice of algorithms:
•Easy to use •Derived from
heterogene
ous data •Supporting evidence
suggesting better than morphology alone.
•Many to choose from
•Can retro test on own data
• Little evidence to support transferability
•Barrie et al *2017 Fertil Steril
•Takes time and
expertise •Data and
experience
grow quickly •Can be as
simply or complex as you wish.
• Reassurance that built and validated in house
* ‘These resultshighlight the need for the development of in-house ESAs that are specific to the patient, treatment, and environment.’
