Question

In vitro fertilization (IVF) involves fertilization occurring in a dish, with the resulting embryo being allowed to develop for several days before being placed into the uterus. GIFT (gamete intrafallopian transfer) involves surgically placing the egg and sperm into the woman's oviducts, but it does not involve in vitro fertilization. Embryos can be frozen for later use through a process called vitrification, which preserves the embryos without degradation. Cells can be safely removed from a blastocyst for genetic testing without harm to the embryo.
