This calculator provides an estimated success rate for egg freezing based on several key factors. Please note that this is a probabilistic estimate and individual outcomes can vary significantly due to numerous biological and lifestyle factors not accounted for in this simplified model.
Excellent
Good
Average
Poor
High
Medium
Low
