Temperature, oxygen concentrations, and pH are all important factors in an embryo’s environment, which may impact on embryo viability if they deviate from desired levels. Characterisation of changes in these factors throughout embryo culture for in vitro fertilisation (IVF) has been limited due to measurement difficulties. Ms Blomfield used engineering principles and mathematical modelling to describe the physical environment that embryos may be exposed to throughout an open embryo culture system, which is used by the majority of IVF clinics worldwide. She identified many simple practical steps that minimise changes in embryos’ physical environment and thus minimise its effect on embryo viability. Her findings provide a basis for
