In Vitro Fertilization (IVF)
Once the egg donor has been screened and chosen, she is stimulated with medication to produce multiple eggs. After the eggs have grown to a specific and appropriate size, an egg retrieval procedure is performed. Most egg donors produce a high quantity of eggs, and are of good enough quality to ensure maturation to a healthy embryo stage. Careful screening will produce the best results.
During the in vitro fertilization (IVF) process, the sperm you provide is combined with the egg donor’s eggs in the laboratory to create embryos. At this point, the embryos may be frozen if genetic testing is desired, or they are transferred into your gestational carrier (or surrogate’s) uterus as fresh embryos via an intrauterine catheter. If frozen, they will be thawed and then replaced into the uterus of the gestational carrier. After transfer, any remaining, viable blastocysts can be frozen for later use if desired by the intended parents. A pregnancy can be detected 11 to 12 days after the embryo transfer.
