Egg Freezing – Oocyte Cryopreservation – Is The Process Of Retrieving Eggs From A Woman’s Ovaries, Freezing Them At Very Low Temperatures, And Storing Them For Future Use. Advances In Vitrification Technology – A Rapid-Freezing Technique That Virtually Eliminates The Formation Of Damaging Ice Crystals – Have Transformed The Reliability Of Egg Freezing Over The Past Fifteen Years. Survival Rates For Vitrified Eggs Now Exceed 90 Percent, And Pregnancy Rates From Frozen Eggs In Experienced Hands Are Broadly Comparable To Those From Fresh Eggs Of Equivalent Quality. Egg Freezing Allows A Woman To Preserve Her Fertility At Its Current Quality – To Essentially Pause The Biological Clock As It Affects Her Eggs – And Use Those Eggs At A Later Time When She Is Ready To Attempt Pregnancy. It Does Not Guarantee A Future Pregnancy, But It Significantly Improves A Woman’s Options If She Needs To Delay Childbearing For Medical, Personal, Or Professional Reasons.
