In current state of the art, early embryos having undergone cryopreservation implant at the same rate as equivalent fresh counterparts. [2] The outcome from using cryopreserved embryos has uniformly been positive with no increase in birth defects or development abnormalities, [3] [8] also between fresh versus frozen eggs used for intracytoplasmic sperm injection (ICSI).

Gestation, called pregnancy in humans, is the period of time during which the fetus develops, dividing via mitosis inside the female. During this time, the fetus receives all of its nutrition and oxygenated blood from the female, filtered through the placenta , which is attached to the fetus' abdomen via an umbilical cord .
