other rabbits to give birth to young rabbits by“borrowing the abdomen”.,In,1959,,,Minj,ue Zhang,a,Chinese,-,American biologist,,finished this experiment again,and achieved a success.,On July

ivf.Human genetic material exists in the chromosomes of sperms and eggs nucleus ,and the cytoplasm around nucleus,plays an important part in providing nutrition and sustaining life.This kind of test tube babies are for those women who have oviposit function,but because of poor physical conditions,or older,causing the eggs quality is not so high,and the energy is poor.Specific method is to remove her nucleus of an egg cell,into a young,healthy womens cytoplasm of a egg,forming a new,high-quality egg,but it still expresses the genetic characteristics of the previous woman.Then combine this egg and her husbands sperm together in vitro to come being to a fertilized egg,implanted back into the first womans womb,so she gives birth to a healthy children that has no relationship with the third people providing the cytoplasm .,3.4,The technology of ooplasm,substitution,Also known as the fourt,10,4.,The advantages of ivf,Test-tube baby technology,a kind of assisted reproductive
