20 years babies from the test tube not without risk
20 years after the birth of the first baby from the test tube the technology behind artificial fertilization is also today not yet perfect. Two today, Thursday, in New England Journal OF Medicine published studies show that artificial fertilization means a residual risk for the baby, over which becoming parents to know would have. The realizations could provide for controversy discussions, since they unite preceded studies contradict. These proved artificial fertilization a good certification.
The statistics are remarkable, stressed the researchers. Babies from the test tube come twice as frequently like baby with a birth error, naturally witnessed, to the world. As a study of the University OF Western Australia showed, had approximately nine per cent of the babies a birth error witnessed by an artificial fertilization even if the babies into the world came in time. In the comparison to it the portion was with “normally” witnessed babies about 4,2 per cent.
Accomplished in the second study, at the center for Disease control and Prevention, were examined 42,000 babies witnessed by artificial fertilization. Even if single births were, had 6.5 per cent of the babies a small birth weight. The weight twice as often lay under it as with children under 2,7 kilograms, naturally witnessed, and. A too small birth weight increases the risk of a mental development delay by the three-way.
As positive the scientists see that the probability amounts to bring by an artificial fertilization a healthy of child to the world 90 per cent. The question, why babies from the test tube possess a higher risk for a birth error and/or a smaller birth weight, is still unsettled. Artificial fertilizations become ever more popular. According to Washington Post in the USA in the basis year 1998 82,000 interferences were accomplished. 29,000 baby came this way to the world.
