Fresh Versus Frozen
Embryos can be either “fresh” from fertilized egg cells of the same menstrual cycle, or “frozen”, that is they have been generated in a preceding cycle and undergone embryo cryopreservation, and are thawed just prior to the transfer. The outcome from using cryopreserved embryos has uniformly been positive with no increase in birth defects or development abnormalities, also between fresh versus frozen eggs used for intracytoplasmic sperm injection (ICSI). Children born from vitrified blastocysts have significantly higher birthweight than those born from non-frozen blastocysts.

Famous quotes containing the words fresh and/or frozen:
“Camillo. Prosperity’s the very bond of love,
Whose fresh complexion and whose heart together
Affliction alters.
Perdita. One of these is true:
I think affliction may subdue the cheek,
But not take in the mind.”
—William Shakespeare (1564–1616)
“Others greater than I have already eulogized you, but none of them ever had the pleasure I had to feel the caresses of your warm, soft hands, to merit your warm embrace that was reserved only for us, to see your half-smile that always told us so much, that same smile which is no longer, frozen in the grave with you.”
—Noa Ben-Artzi Philosof (b. 1978)
