For the embryos to develop correctly, it is necessary that they are kept in controlled and stable conditions. They must be at 37ºC and a high relative humidity (approximately 95%). Regarding gases, the current trend is to maintain a low concentration (5-7%) of both carbon dioxide (CO2) and oxygen (O2). However, good results are also obtained with the atmospheric concentration of O2, at about 21%.
