IVF Used in Record-setting 1 in 100 Babies in U.S.
A new report finds that one or two of every 100 babies born in the United States now are
conceived with advanced fertility help. In vitro fertilization, or IVF, in which eggs and
sperm are mixed in a lab dish, led to a record 61,740 babies in 2012. That is 2,000 more
than the previous year and 1.5 percent of all births in the nation.
The report by the Society for Assisted Reproductive Technology also finds that more women
are using one embryo at a time to avoid multiple births, which raise the risk of prematurity
and other problems. Only 4 percent of women under 35 used single embryos in 2007 but that rose
to 15 percent in 2012.

在美国创下了每100个婴儿有1个试管婴儿的记录
一份新的报告发现,现今每100个出生在美国的婴儿就有1-2个是受过先进生育技术的帮助:体外受精或者试管婴儿,是把卵子和精子混合在实验室的培养皿中的,这创造了2012年试管婴儿日出生61,740的纪录。这占全国所有新生儿的1.5%,比前一年多2000个。
辅助生殖技术协会的报告还发现,越来越多的妇女使用一个胚胎以避免多胎妊娠引起的早产和其他问题的风险。2007年, 35岁以下的女性使用的单胚胎的比率只有4%,在2012年时上升到15%。
