Before embarking on a medically invasive, expensive and emotionally taxing effort to get pregnant through in vitro fertilization, it sure would be nice to get a good sense of whether it’s likely to work. After all, only about 1 in 4 attempts resulted in a live birth as recently as 2007. So researchers from England and Scotland scoured data from more than 144,000 IVF cycles in the United Kingdom and looked for factors that might predict which couples stood the best chance of having a baby with assisted reproduction and which faced long-shot odds.

The British media is abuzz with news that a triplet was born 11 years after her twin sisters. It seems that, in the age of frozen embryos, all is possible. The Daily Mail newspaper says experts proclaim the delayed birth to be a "record gap" for babies conceived at the same time via in vitro-fertilization. Twins Bethany and Megan Shepherd were born in Britain in 1998 and their remaining sister, Ryleigh, was born last month. Apparently the Shepherds have more embryos from the same batch on ice, the story says.

British biologist Robert G. Edwards, whose contributions to the technology of in vitro fertilization have made more than 4 million couples parents, has been awarded the 2010 Nobel Prize in physiology or medicine. Working with Dr. Patrick Steptoe, Edwards, now 85, developed the techniques for removing mature eggs from a woman's ovaries, fertilizing them in test tubes and inducing them to begin dividing before implanting them back in the mother. Their efforts yielded the July 25, 1978, birth of Louise Brown, the first "test tube baby," both demonstrating the success and the safety of the technique and bringing hope to infertile people all over the world.

In 1978, Louise Brown was born -- and won the distinction of being the world's first "test tube baby" because she was conceived thanks to then-innovative in-vitro fertilization techniques, or IVF, developed by British biologists. Since then, IVF has more than grown up. The Los Angeles Times reports Monday that the technique and one of its pioneers are making headlines anew in "IVF innovator Robert G. Edwards wins Nobel. " Use of such techniques, also called assisted reproductive technology, has more than doubled in the last decade and accounts for 1% of all infants born in the United States each year, according to the Centers for Disease Control and Prevention.

One of the reasons so many couples using in vitro fertilization wind up with twins – and even triplets – is that they choose to transfer multiple embryos into the womb to insure at least one of them will develop into a baby. But carrying multiples can be risky for mother and babies. If only there were a way to reliably predict which embryos are most likely to grow, perhaps couples would be more willing to follow the government’s recommendations and transfer only one or two embryos at a time.

Doctors and scientists are still learning about what effects in vitro fertilization may have on the health of children. But a new study of children's test scores provides evidence that IVF conception "does not have any detrimental effects on a child's intelligence or cognitive development," the author says. Researchers looked at the academic test scores of 423 Iowa children ages 8 to 17 who were conceived by IVF and at the test scores of 372 matched peers from the same schools. They also analyzed data on the parents of the IVF children, including ethnicity, education, age and marital status.

In vitro fertilization treatment can be emotionally grueling and prohibitively expensive, and some people decide they can't — they absolutely can't — go through it again. If only there was a way to accurately predict the chance that such treatments would lead to a real-life bundle of crying, needy, with-you-for-18-years-minimum joy. Stanford University researchers say they've done it, at least for women who've already had one round of IVF. In research published online Monday in Proceedings of the National Academy of Sciences, they explain their model for predicting the odds that a live birth will result from IVF treatment.

One of the early fears about in vitro fertilization at its inception more than 30 years ago was that the procedure might cause genetic or other health problems in children conceived in that manner. It's clear that IVF is very safe. However, several studies suggest a slightly higher risk of birth defects and some types of illness among children born via IFV that parents should be aware of. The latest study indicates cancer may occur more often. Previous studies looking for a link between cancer and IVF have found nothing.

Last month, the U.S. received a set of grades from the March of Dimes, the nation's leading organization committed to preventing preterm births, that were nothing short of horrible. The report card on premature births compared preterm birth rates with national objectives. Overall, the nation received a D. Not a single state merited an A, and only one, Vermont, earned a B. Eighteen states and Puerto Rico and Washington, D.C., received an F, and California squeaked by with a C.

Re "Free-market baby making," Opinion, July 24 Gregory Pence claims that the Vatican is "perverse" in condemning in-vitro fertilization (IVF). The Vatican -- and anyone with a heart -- knows a married couple that wishes to conceive a child and cannot suffers intensely. Nevertheless, no one has an absolute right to a child. The conceived child is the one who possesses rights, which IVF gravely tramples upon. IVF kills the innocent. It requires the creation up to a few dozen fertilized eggs.
