Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

Summary

Researchers are collecting images of eggs and embryos from time-lapse incubators to train an AI system called CHLOE. The goal is to see if the AI can accurately predict which embryos will reach the blastocyst stage, a key step in IVF. This study involves women aged 18 and older whose embryos are cultured in a compatible incubator. The findings could help improve embryo selection in fertility treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
AI evaluation of oocytes inside a time-lapse incubator
What this could lead to
If successful, this could improve how clinics select embryos for IVF, potentially increasing the chances of a successful pregnancy.
What could go wrong
This is an early data-collection study, not a treatment trial. The AI's predictions need validation and may not improve clinical outcomes.
