What is the difference between slow-freeze and vitrification?

Freezing uses modern cryopreservation, most often vitrification, to store eggs or embryos for future use. Important issues include age at freezing, the number frozen, thaw survival, storage fees, and the difference between storing eggs before a partner is chosen versus storing embryos after fertilization. Freezing creates future flexibility, but the result still depends heavily on age and egg or embryo quality at the time of freezing.
