In vitro fertilization can be a rocky road, and it's helpful to know your odds when you start trying to conceive. There are plenty of online tools out there to help you calculate your chances of success, but nothing as accurate as the new IVFpredict tool out of the UK.
This new online model takes way more information into account than the widely-used Templeton model, which is over 20 years old. It asks for a woman's age, how long she's been trying to get pregnant, whether she plans to use her eggs or a donor's, which drugs she'll be using, pregnancy and IVF history and the cause of infertility. It also accounts for new technology — intracytoplasmic sperm injection (ICSI) in particular.
Medical statistician and study contributor Andrew Smith says IVFpredict gave a more accurate prognosis in 52.5 percent of cases.
Smith used UK data in his study. In the US, the Society for Assisted Reproductive Technology (SART) launched its own prediction tool in January, also asking for a woman's height and weight (since obesity may hinder your chances of getting pregnant).
Regardless of which prediction method you use, you don't need a doctor's help to use them. They're both available online; all you have to do is input your data.
