AI in Fertility and IVF Embryo Selection Quiz

Answers and explanations appear as you take the quiz.

1. What does a time-lapse incubator like the EmbryoScope do?
   • Freezes embryos instantly
   • Photographs embryos every few minutes without removing them
   • Edits embryo DNA
   • Transfers embryos into the uterus
2. What did the 2024 Nature Medicine randomised trial of iDAScore find?
   • AI doubled live-birth rates
   • AI was banned from clinics
   • AI was not shown to be non-inferior on clinical pregnancy but greatly cut assessment time
   • AI made no difference to embryologists' workload
3. Why can embryo ranking not raise a patient's overall chance if all embryos will eventually be transferred?
   • Ranking only changes the order embryos are used, not their quality
   • Ranking damages embryos
   • Ranking is only used for frozen embryos
   • Ranking increases the number of embryos
4. Why are AI embryo models affected by selection bias?
   • They use too many images
   • Only transferred embryos, already chosen as best-looking, have outcome labels
   • All embryos have outcome labels
   • Models ignore implantation data
5. What range of AUC values do implantation prediction models typically report?
   • 0.99 to 1.0
   • 0.95 to 0.99
   • Exactly 0.5 always
   • Often around 0.6 to 0.7
6. Which grading system do embryologists commonly use to assess blastocysts by eye?
   • Gardner grading
   • Apgar score
   • Gleason score
   • Glasgow Coma Scale
7. Why are labels cleanest from single-embryo transfers?
   • They are cheaper
   • They always result in pregnancy
   • The outcome can be linked to one specific embryo
   • They use no time-lapse imaging
8. How have genetics societies generally viewed polygenic embryo screening?
   • As proven and recommended for all patients
   • As widely criticised and unproven
   • As required by law
   • As identical to time-lapse imaging
