Effect of Hyaluronan on Developmental Competence and Quality of Oocytes and Obtained Blastocysts from In Vitro Maturation of Bovine Oocytes

Table 2

The effect of HA supplementation on developmental competence of bovine oocytes (5 replicates) (mean ± S.D.).

Medium	𝑛 of oocytes	Cleaved 𝑛 (%); (mean ± S.D.)	Blastocyst 𝑛 (%); (mean ± S.D.)
0.035% HA	174	114 (65.5)	22 (13)
		(22.8±5.26)^A,a	(4.4±3.04)^a
0.07% HA	169	124 (73.4)	39 (23.1)
		(24.8±7.05)^b	(7.8±2.38)^b
Control	186	148 (79.5)	33 (17.7)
		(29.6±6.66)^B	(6.6±4.97)

Values within column with different superscripts differ significantly: ^a,b𝑃<0.05;  ^A,B𝑃<0.001 (test χ ²). 𝑛: number.
