...awful lot of people at large in the world began their lives in a dish. Just over 30 years ago, a British baby named Louise Brown became the first viable child conceived by in vitro fertilization. Now the 3.5 million people who have followed her match the population of Lithuania. But bringing those millions into existence was not easy. On average, only a quarter of all IVF attempts with fresh eggs yield a live birth; frozen eggs perform even worse, topping out at just 17%. According to an announcement made yesterday by a team of researchers in the United Kingdom...
...most women undergo multiple attempts, each of which can cost $5,000. Fischel's procedure runs an extra $2,750 or so - but paying a premium price once is easily cheaper than paying the lower price over and over. What's more, while couples who choose the in vitro route dearly want a child, they don't always want more than one.

The Geron team began its work with what is known as a presidential stem-cell line - stem cells derived from discarded in vitro-fertilization embryos that already existed in 2001 when then President Bush decided to prohibit the use of federal funds to pursue human embryonic-stem-cell work.

Pretty good, according to a new study, which finds that women's chances of live birth via IVF may be similar to those of other women their age in the general population - better for younger women, not as good for older ones...
