Reduced oxygen concentration during human IVF culture improves embryo utilization and cumulative pregnancy rates per cycle

22 Oct 2019

Abstract excerpt

Abstract STUDY QUESTION Do different oxygen levels during human IVF embryo culture affect embryo utilization, cumulative IVF success rates per cycle and neonatal birthweight? SUMMARY ANSWER After 2 days of culture, a lower oxygen level (5%) leads to more good-quality embryos and more embryos that can be cryopreserved, and thereby to a higher cumulative live birth rate per cycle when compared to embryo culture in...
