Summary

This study looks at whether changing the oxygen level during embryo growth in IVF can improve the chance of having a healthy, full-term baby. About 980 women undergoing IVF will have their embryos grown in either a constant 5% oxygen or a sequential 5% then 2% oxygen environment. The goal is to find out which method leads to more live births and healthier children.
