Many babies of manual working are the heavier to inseminate outside the body
Tokyo, December 26 (Xinhua) ' Reporter Lan JianZhong) Japan thick to grow, work the intersection of province and seminar say they follow-up investigation baby that technology give birth to find through inseminate outside the body a few days ago, manual working is the more to inseminate outside the body in the course, the heavier the weight of baby born is. The seminar has investigated about 27,000 through the mature weight when born in of technology of inseminating outside the body from 2007 to 2008. Found finally, if transplanted the embryonated egg back to the uterus directly, baby's weight was 3003 grams on average; If transplant the embryonated egg to the uterus during the course of training outside the body to embryo bubbles, baby's average weight is 3025 grams; If the embryonated egg is frozen and kept, baby's average weight is 3070 grams; If the embryonated egg is trained and frozen and kept, unfreeze and transplant outside the body afterwards, then baby's weight is up to 3108 grams on average. In a word, these manual working done on embryonated egg large for rate of bed improved, the heavier the baby is. In the past 10 years, some report said constantly, the child given birth to through auxiliary reproduction technology, it is very high to present the unusual frequency of genomic imprinting, lead to the fact the mechanism of regulating the genetic function becomes abnormal. It is that the development is too fast that one of them displays, and then cause foetus' inborn defect. Statistics reveal, under the normal situation, the morbidity of the inborn defect is about 1/10000, and the baby given birth to through auxiliary reproduction technology, the morbidity of the inborn defect exceeds 1%.
