Embryo Cryopreservation

When any art procedure is done,there may be more embryos obtained than are normally transferred. Couples can elect to have them frozen, or cryopreserved. Later, when another pregnancy is desired, these embryos are thawed and transferred into the uterus without having to undergo ovarian stimulation and oocyte retrieval necessary for ivf. If pregnancy does not occur, frozen embryos offer a couple another chance to conceive.
