The idea of test-tube babies may make you either delighted at the wonders of modern medicine or irritated while considering the moral, or legal, or technological implications of starting life in a laboratory. But if you’ve ever been pregnant yourself, one thing is certain: You wonder what it’s like to carry a test-tube baby. Are these pregnancies normal Are the babies normal
The earliest answers come from Australia, where a group of medical experts at the Queen Victoria Medical Center in Melbourne have taken a look at the continent’s first nine successful "in vitro" pregnancies. The Australians report that the pregnancies themselves seemed to proceed according to plan, but at birth some unusual trends did show up. Seven of the nine babies turned out to be girls. Six of the nine were delivered by Caesarean section (剖腹产手术). And one baby, a twin, was born with a serious heart defect and a few days later developed life-threatening problems.
A. Whether the test-tube babies would be legally accepted by society.
B. Whether the test-tube babies would be normal from pregnancy to birth.
C. Whether modern medicine is advanced enough for test-tube babies’ delivery.
D. Whether there would be always more girls than boys out of the test-tube babies.
