LONDON (Reuters) - Want to know your chance of having a baby through in-vitro fertilization? There's an app for that.

British researchers have devised a formula which they say gives a highly accurate prediction of the potential success of IVF, to help couples decide whether to try the treatment.

They have made it available online as a simple computer calculator application, and say it will soon be available for download on Apple's iPhones and other mobiles.

Scientists from the Universities of Glasgow and Bristol analyzed the details of more than 144,000 IVF cycles to produce a statistical model that can give a prediction of live birth which is up to 99 percent accurate.

"Treatment-specific factors can be used to provide infertile couples with a very accurate assessment of their chance of a successful outcome following IVF," said Scott Nelson of the University of Glasgow, who led the research.

Nelson, whose work was published in the Public Library of Science (PLoS) Medicine journal, said that up until now estimates of success have not been very reliable.

The formula takes into account the woman's age, number of years trying to get pregnant, whether she is using her own eggs, the cause of infertility, the number of previous IVF cycles and whether she has previously been pregnant or had a baby.

"The result of this study is a tool which can be used to make incredibly accurate predictions," he said in a statement.   Continued...
