The entire IVF process is governed by the biology of sperm, egg and embryo, and we must optimize conditions to protect the “product” against exposure to adverse external factors. The problem lies in the lack of agreement of these conditions.
The human embryo is sensitive to light, temperature and other environmental conditions. Pollutants can settle on workspaces, and although embryos bathed in their culture media overlaid with a layer of light paraffin oil, attention has to be paid to the risk of toxins infiltrating the barrier because embryos lack an immune system to stave off harmful environmental contaminants.
