Table 4 Number of fresh or frozen spermatozoa bound to the zona pellucida of oocytes incubated with or without anti-ZPC antibodies.

Groups		Anti-ZPC antibodies	No additive
Fresh semen	No. Oocytes	31	32
	Spermatozoa/oocyte (mean ± SEM, n = 2)	60 ± 6	58 ± 5
Frozen semen	No. Oocytes	39	39
	Spermatozoa/oocyte (mean ± SEM, n = 2)	71 ± 7	64 ± 8

No statistical difference was observed between the columns in the same line (for fresh semen F = 0.05 and p = 0.82, for frozen semen F = 0.44 and p = 0.51)
n: number of replicates
