what are test tube babies
What is a test tube baby; how is it produced? Researches in the reproductive biology of human beings have yielded wonÂ­derful results both for the control of the population and for production of children in cases where the parents are unable to produce children. LiterÂ­ally test tube bay means production of babies in a test tube. But in practice test tube baby means artificial fertilization of egg and sperm outside the body and implantation of the zygote into the womb of the mother. So far no one has succeeded in growing a human embryo completely into a child on culture media.
