Cryopreservation by Vitrification and Frozen Embryo Transfer (FET)
Embryo freezing: Embryo freezing is the best-studied and most widely used form of fertility preservation. Embryos are obtained through an advanced fertility treatment called in vitro fertilization (IVF). IVF has resulted in millions of live births in women and men with infertility. The ovaries are stimulated with injections of hormones that stimulate follicles on the ovaries to produce mature eggs. The process is closely monitored during 1-2 weeks of ultrasounds and blood draws.
Once the eggs are mature, the egg retrieval procedure is performed using an ultrasound-guided needle while you are asleep under anesthesia. The process takes about 20 minutes. Eggs are fertilized with sperm and fertilized embryos are frozen for later use.
