Table 1. Differences between the physiological values for O₂ and temperature recorded by García-Martinez et al. (2018, 2020) and the values routinely used during in vitro production of pig embryos.

	Value routinely used in vitro	Physiological value	Improved parameters with the physiological values
Temperature	38.5ºC	37ºC	Monospermy rate (20% higher)
Temperature	38.5ºC	37ºC	Blastocyst rate (15% higher)
Oxygen	20%	7%	Cleavage rate (28% higher)
			Blastocyst rate (6% higher)
			Nº cells/blastocyst (30 cells more).
