Study Notes

Embryo Culture Environment

Successful fertilization requires the addition of lipids from the Krebs cycle in the diet embryo culture environment.
Current culture media contain less than 10 mg/L of lipids, which is insufficient for vitality and contributes to low fertilization success.
Oocyte maturation, fertilization, and pre-implantation embryonal development require a continuous and balanced supply of energy substrates.

Energy Substrates and Nutrients

Embryonal environment oxygen tension, pH, and ion concentration are crucial for effective culture.
Energy substrate requirements are similar to those for in vivo embryo development.
D-lactic acid deficiency is the source of energy in transport and utilization by embryos.

Culture Media Components

Data on selecting culture media components for in vitro embryo development in animals and humans are limited.
Most fertilization centers culture embryos in media containing up to 10 mg/L of lipids.

Key Performance Indicators (KPIs)

"Home program" baseline normative values for each KPI have been established to show a defined pattern over time.
KPI metrics, such as the Energy Eye Report and Total Case Asking Effectiveness Rate, have been developed to reinforce service balancing and promote adoption of operation clinical order sets.
12 KPIs have been identified, consisting of 8 efficacy, safety, and quality strata and 4 environmental edge categories.

Success Rates

The impact of lipid emulsions on in vitro fertilization success rates and outcomes is relevant for the reproductive medicine community.
A study comparing the impact of an intralipid bolus to a saline bolus on fertilization rates and embryo morphology scores found no significant differences.
Future studies are needed to elucidate the embryonic kinematics of oocytes subjected to the intralipid bolus during follicular aspiration.
