Frequently Asked Questions About Egg Freezing
Egg freezing, also known as oocyte cryopreservation, is a fertility preservation technique in which mature eggs are collected, frozen and stored for potential future use when you are ready to pursue pregnancy.
Egg freezing may be considered by women who wish to preserve their fertility for medical reasons, personal or family-planning reasons, or because they may have a condition or family history that could affect ovarian reserve. Your fertility specialist can help determine whether it is appropriate for you.
The process typically involves ovarian stimulation with hormone medication, followed by ultrasound monitoring and egg retrieval. The mature eggs are then frozen using vitrification, a rapid freezing technique designed to minimize ice crystal formation.
Frozen eggs can be stored for an extended period under carefully controlled conditions. The permitted storage duration may depend on applicable regulations, consent and individual circumstances, so your fertility team can explain the options available to you.
No. Egg freezing preserves eggs for potential future use, but it does not guarantee pregnancy. Future outcomes can depend on factors including age at the time of freezing, the number and maturity of eggs stored, sperm factors and other individual fertility considerations.
