scientists made a great breakthrough this year in england when the first“test-tube” baby was born.the birth was the result of many years of research by doctors.the doctors did the research in groups to help the women who cannot conceive a baby in the normal way.��
what happened when the baby was born “from a test tube”?well, the baby did not literally grow in a test tube.the first stage of the process was that the egg from the woman and the sperm from the man were put together in the test tube.after all, the embryo was put into the womb of a woman.this process was difficult.but it was successful, so the baby was eventually born, like any other, from a woman, only the woman wasn’t the baby’s real mother, but a sort of“carrier”of a baby produced by another couple.
obviously, this method is help to couples who can’t have children because of physical problems in the woman.but very difficult moral problems arise in the kind of situation.take, for instance, a case that happened this year.a couple who wanted a baby advertised for a woman to have a child by the father of the couple.they offered the woman a lot of money.the woman was made pregnant by artificial insemination; in this case, the woman“employed”to bear the child was its real mother.when the baby was born, the woman refused�� to give it back to the couple.but, in the eyes of the law, the woman had a right to keep the children because she was its biological mother.��
you could argue that we should change the law to deal with this kind of situation.in earlier times, there were always healthy babies needing adoption, because family planning methods were not so effective as they are now.these days, however, most of the children who can be adopted are over six years old, often handicapped in some way.so a couple who want a young healthy baby cannot always adopt one, this is why the“test-tube”baby is in demand.but is it normally right to use this method?should we temper with nature in this way?even if we change the law, would this be the right step to take?��
