What Is In Vitro Fertilization? PDF Print E-mail


Simply stated, IVF involves removing eggs from a woman, fertilizing them in the laboratory (in a culture dish, actually, not a test tube) and then transferring the fertilized eggs, or zygotes, into the uterus a few days later.



More specifically, after superovulation with hormones to produce multiple eggs, the IVF team places the retrieved eggs in sterile culture media along with processed sperm and keeps them at normal body temperature inside an incubator, where fertilization and early cell division take place. Then the team returns the fertilized and dividing eggs to the uterus. From that point, if the zygotes implant successfully and become embryos, the pregnancy progresses as it would naturally.
