Table 2. Oocyte activation or fertilization and embryo development in vitro after mice were exposed to cat stress for 24 h starting from 24 h following eCG injection.

Oocyte treatment	Mouse treatment	Oocytes cultured	% Oocytes activated/fertilized (n)	% Blastocysts (n)	Cell number/blastocyst
Activation	Control	115	98.1±1.3 (113)^a	26.7±0.3 (30)^a	38.2±2.9^a
	Stressed	118	97.1±1.5 (116)^a	8.1±1.7 (11)^b	23.6±1.7^b
Fertilization	Control	136	92.6±2.3 (127)^a	87.1±2.4 (110)^a	66.7±4.4^a
	Stressed	172	87.6±4.4 (155)^a	41.7±8.4 (68)^b	39.4±3.9^b

a–b: In the same column, values without a common letter in their superscripts differ (P<0.05) within oocyte treatments.
