Table 3. Effects of phospholipase C inhibitor U-73122 on motility of boar spermatozoa incubated with a cAMP analog^*

		Incubation Time (min)
U-73122 (mM)		0	180

0 (control)	Motile sperm (%) ${dagger}$	77 ± 6 ${ddagger}$	77 ± 6 ${ddagger}$
	Hyperactivations $§$	–	+++
0.02	Motile sperm (%) ${dagger}$	73 ± 6 ${ddagger}$	50 ± 10\|\|
	Hyperactivation $§$	–	–

*Boar spermatozoa were incubated with 0.1% polyvinyl alcohol and 0.1 mM cBiMPS, but without sodium orthovanadate (n = 3).
${dagger}$ Values are means ± SD.
${ddagger}$ Values differ significantly (P < .05).
$§$ Percent of spermatozoa exhibiting the hyperactivation (–, 0%–10%; +, 11%–30%; ++, 31%–50%; and +++, >50%).
\|\|Values differ significantly (P < .05).
