Embryo culture

Growing embryos in the laboratory in a carefully controlled incubator.

Clinics, laboratory & costs

Embryo culture is the process of keeping embryos in nutrient media inside incubators that control temperature, humidity and gas concentrations, mimicking conditions in the body. Culture usually continues to day 5 or 6 so the laboratory can see which embryos develop furthest. Because stable conditions are essential, South African laboratories run backup power and continuous monitoring.

Also known as: culture media, extended culture, incubation
