IDAScore and the AI revolution in embryo selection

02 / 07 / 2025

Artificial intelligence (AI) is transforming medicine and diagnostics. In the field of assisted reproduction , AI-based technologies are opening up new possibilities for optimising clinical processes and improving treatment outcomes.

Some of the most promising tools in this field are those designed for embryo selection. AI allows an objective analysis of the developmental stage of embryos and, in this way, assists embryologists in the selection of embryos that have a higher probability of success. A clear example of this advance is the iDAScore technology, which applies AI to evaluate embryos in an automated and non-invasive way, bringing a new level of objectivity to embryo selection.

What is iDAScore?

IDAScore is an AI system that analyses images of embryo development obtained using the EmbryoScope Time-Lapse incubator and assigns a score to each embryo in the culture plate based on its probability of implantation. This score helps the embryologist to make his decision in the embryo selection process.

What are the advantages of iDAScore?

IDAScore provides an objective and standardised classification based on the automated analysis of large volumes of data. In fact, several studies have shown that its predictive capacity is comparable or even superior to manual evaluation, which makes it a very valuable tool during the embryologist's decision making. This technology allows:

  • Increased accuracy and objectivity: by providing an objective and consistent assessment of embryos, it helps embryologists make more informed decisions, reducing human bias.
  • Automation of the process: reducing the workload of embryologists.
  • Based on clinical evidence: the system has been trained with data from thousands of optimally developing embryos.
  • Improved implantation rates: allows prioritisation of embryos with the highest probability of successful development.

Is it safe to use iDAScore for embryo selection?

IDAScore is a complementary tool to the embryologist's expertise that has been designed to improve decision-making without replacing, in any case, professional judgement. Moreover, its implementation does not involve any direct intervention on the embryos, as it is based on the analysis of images, without intervening directly on the embryos. Therefore, it is a very safe tool, which only provides advantages in the selection process.

At Barcelona IVF we are committed to incorporating the most innovative technologies, such as iDAScore, in order to offer the best results to our patients.
