The simple answer is, it can’t. In a well-functioning culture system, the oil should only act as a cover, protecting the gametes and embryos from changes in the environment and potential contaminants. But if the oil quality is sub-optimal, it can decrease embryo development. Most oils are produced from petroleum, which means that embryotoxic components may be present due to the production process and origin of the raw materials.
