A gestational surrogate carries a child conceived from the genetic material of both of the intended parents. The embryo is produced from an IVF cycle using the eggs and sperm from the intended mother and father.
In gestational surrogacy, the infertile couple undergoes a standard IVF cycle to produce their own genetic embryos. The reproductive cycles of the surrogate and mother are synchronized so that the embryos can be transferred to the surrogate at the appropriate time.
In some instances, donor egg and/or donor sperm may be used by the intended parents to produce the embryo.
