Table 1.

Effect of Resveratrol supplementation on exteriorization of phosphatidylserine, assayed by Annexin V/Hoechst 33342/PI staining, in vitrified oocytes. Data are presented as mean percentage.

Group	N oocytes	% viable oocytes (A− PI−)	% apoptotic oocytes (A+ PI−)	% dead oocytes (PI+)
CTR	310	66.1a	28.4a	5.5a
A	150	78.7b	15.3b	6a
B	124	83.1b	16.9b	0b
C	122	80.3b	18.9b	0.8b
D	114	81.6b	17.6b	0.9b

Different superscripts within the same column indicate significant differences (P < 0.05).

CTR: control group; (A) 2 μM R supplementation during IVM; (B) 2 μM R supplementation during the postwarming incubation for 2 h; (C) 2 μM R supplementation during vitrification/warming and 2 h after warming; (D) 2 μM supplementation in all previous steps.
